Description

Mobile Radio Communication Device with Radiation Detector

Field of the Invention

The utility model relates to mobile communication devices (mobile phones, smartphones, etc) with ancillary equipment, specifically to portable radio communication devices with the built-in module which serves as the dosimeter and radiometer and is intended for taking measurements and processing measurement results (Dosimeter-Radiometer Classic or DO-RA.Classic, since it utilizes the classic Geiger-Muller counter).

Following Chernobyl and Fucushima-1 nuclear disasters more people across the globe pay close attention to the effects produced by radiation on human body/organism at the radioactively contaminated sites, in the areas surrounding the contaminated zones and also in remote locations where radioactive products could be carried into by wind, rain, underground water, rivers, seas and oceans. There are various designs of dosimeters and radiometers which have a separate housing which accommodates equipment and visual indicators. However, it is inconvenient and inexpedient to provide all people with mobile radiation monitoring devices that shall be constantly worn on body and each containing individual batteries, alarms and indicators.

Prior Art

There are existing models of mobile phones combined with built-in ancillary equipment.

There is the cellular phone model which incorporates the separate command device in form of mobile phone enclosure intended for converting electrical signal generated by the electronic unit following actuation of the alarm sensor into mechanical signal with the help of the electromechanical unit. This mechanical signal is sent to the cellular phone keypad for generating the alarm signal by calling the phone user with the help of the phone speed dial function and also provides for possible use of GSM communication with blocking of the incoming calls (RU No.102282).

There is also the mobile (cellular) phone model with additional functions which incorporates the transmitter and receiver (transceiver) (for transmitting and receiving audio (audio alarm) and information signals), the signal processing circuit (which when activated links to the transceiver and the microprocessor for processing signals transmitted and received by the transceiver), the memory, the keypad, the display, the battery and the housing. Besides that, this mobile phone model also has the additional built-in component - the optoelectronic module for measuring distances, areas and volumes and also for processing the measurement results. When activated this optoelectronic module links to the signal processing circuit, keypad, display, battery, transceiver and microprocessor. The latter is capable of deactivating the optoelectronic module and storing the results in case of an incoming phone call. (RU No.70434).

The shortcomings of the existing mobile communication devices are their insufficient functional capabilities that do not provide for adequate radiation monitoring.

Another known mobile communication device, which is most similar to^' the device presented herein, consists of the housing that accommodates the electrically interconnected transceiver and processor connected to the display, keypad, memory, battery and alarms. Besides that, it is equipped with the semiconductor detector, the amplifier and the interface unit connected in series. The interface output is connected to the processor capable of generating audio and visual signals of the dosimeter and the radiometer with the use of the aforementioned alarms and display. (RU No.109625, prototype model).

The shortcomings of this mobile communication device and detector include low sensitivity due to lack of available (commercially produced) inexpensive semiconductor material which (when designed as a single block) would combine such properties as wide band gap and high mobility of carriers (of radiation quanta knock out electrons) in normal environment (without forced cooling).

For example, germanium detectors, that generally possess the required properties, are cooled down to the liquid nitrogen temperature which makes them unsuitable for application in mobile (pocket-size) communication devices. Silicon mono-block detectors contain, in normal environment, too much intrinsic mobile (unbound) electrons. In order to improve sensitivity, it is necessary to increase the volume of the semiconductor to make it more probable that, for example, gamma quantum hits and scatters in it and, consequently, to increase the radiation flux particle count rate. However, increase in the volume entails proportional increase in number of intrinsic carriers which makes additional carriers "poorly observable" and their detection becomes challenging and requires application of cryogentic technology and precision amplifiers, or amplification of signal by avalanche multiplication in strong electric field for recording penetrating radiation events.

In general, the shortcomings of the aforementioned mobile communication device include high cost, complex design and excessive heat release by the semiconductor detector as well as low shock strength and vibration rigidity of the known semiconductors, stringent heat removal requirements, large dimensions and high power consumption inacceptable for mobile communication devices.

Summary of the Inventions

The utility model, in the technical terms, is aimed at creating an effective mobile communication device with radiation detection capabilities and also at extending the range of mobile communication devices.

The technical solution for accomplishing the said goal involves simplification of the design by excluding expensive rare high purity materials and application of the commercially produced highly reliable and proven detector with low heat emission, and hence with less stringent heat removal requirements (without use of cryogentic technology unsuitable for application in mobile communication devices).

The main idea of the utility model is that the mobile communication device consists of the housing that contains the electrically interconnected transceiver and processor connected to the display, keypad, memory, battery, front-facing photographic camera and alarms and also accommodates the radiation detector and the interface unit connected in series. The interface output is connected to the processor capable of generating audio and visual signals of the dosimeter and the radiometer with the use of the aforementioned alarms and display. The radiation detector is the Geiger-Muller (gas-discharge) counter equipped with the voltage multiplier.

Preferably, the radiation detector is capable of measuring ionizing radiation alpha, beta and gamma rays, while the processor includes the software for signaling about tolerable, maximum permissible and intolerable ionizing radiation equivalent doses, measuring ionizing radiation background level (dose rate), plotting diagrams of human organs and systems condition depending on accumulated ionizing radiation dose, generating medical treatment recommendations depending on accumulated ionizing radiation dose and also for displaying relevant visual graphic, tabular and text information messages.

Besides that, the processor incorporates the software for signaling about hourly, daily, weekly, monthly and annual tolerable, maximum permissible and intolerable ionizing radiation equivalent doses as per the RF Radiation Safety Standard NRB 99/2009 and the Radiation Safety Standards of other countries, while the keypad has additional keys for operating the device in the dose metering, radiation metering and (photo) picture taking modes.

The mobile communication device is equipped with the GPS/GLONASS navigation device for locating position anywhere of the Earth. The radiation detector, amplifier and interface unit are housed in the detachable enclosure.

Preferably, the mobile communication device has the front-facing photographic camera for taking photo pictures of ionizing radiation sources with indication of the relevant source parameters.

Besides that, the mobile communication device has the mobile phone/smartphone standard audio jack or universal jack or mini-jack for feeding electric power to the dosimeter and the radiometer as well as for transmitting control signals and also for measuring dose equivalent, dose rate and other parameters. It allows for operating the dosimeter and radiometer and for exchanging data via the digital protocol over the mobile phone/ smartphone audio-signal path by frequency or phase shift keying, or over the USB port in the universal or mini jack or over Bluetooth or over mobile phone/ smartphone NFC channel.

Detailed Description of the Invention

The mobile communication device (mobile (cellular) phone, smartphone) consists of the housing (17) (shown for clarity) which accommodates the processor (1). Connected to the processor are the memory (2), the display (3), the alarms (4), the keypad (5), the battery (6), the GPS/GLONASS navigation device (9) and the transmitting and receiving device (Wi-Fi/GPRS transceiver) (15). The mobile communication device also has the front-facing photographic camera (16) and the Geiger-Muller (gas discharge) counter (8), the voltage multiplier (7) and the interface unit (10) connected in series. The interface unit (10) is connected to the processor ( 1 ) for providing interaction of the latter with all other components of the device.

The device has the mobile phone/smartphone standard audio jack or universal jack or mini-jack or other mobile phone/ smartphone infrastructure (not shown) for feeding electric power to the dosimeter and the radiometer from the main power supply line as well as for transmitting control signals and also for measuring dose equivalent, dose rate and other parameters. It allows for operating the dosimeter and radiometer as well as for exchanging data via the digital protocol over the mobile phone/ smartphone audio-signal path by frequency or phase shift keying, or over the USB port in the universal or mini jack or over Bluetooth or over mobile phone/ smartphone NFC channel, or otherwise with the help of the mobile phone/ smartphone infrastructure.

The Geiger-Muller counter (8) is the sensitive element intended for recording high energy alpha, beta and gamma rays by detecting emission of secondary ionizing particles, photoelectrons or Compton electrons (the Compton effect). The counter (8) is the gas-filled condenser which consists, for example, of the metal tube or the glass tube with metalized walls and the thin metal wire stretched along the tube axis, where the crown discharge (electric arc) occurs when an ionized particle passes through the gas volume.

Ionizing radiation triggers emission of Compton electrons which results in a discharge in the counter (8) gas medium. The discharge sends a current pulse through the counter and thus an ionizing radiation event is detected. The Geiger-Muller (gas- discharge) ionizing radiation counter (8) is capable of measuring high energy gamma, beta and alpha rays. The interface unit (10) is used for counting number of pulses per time unit and for transmitting the obtained data to the processor (1).

The processor (1) has the software for operating the mobile communication device and also for monitoring and accumulating data and signaling about tolerable, maximum permissible and intolerable ionizing radiation equivalent doses, measuring ionizing radiation background level (dose rate) and analyzing its effect on human organs, plotting diagrams of human organs and systems condition depending on accumulated ionizing radiation dose, generating medical treatment recommendations depending on accumulated ionizing radiation dose and also for displaying relevant visual graphic, tabular and text messages on the display (3). The processor (1) software program includes four software modules for various operation modes which are shown in the Figure:

- Information module (1 1) - Dosimeter;

- Information module (12) - Radiometer;

- Information module (13) - Impact on Human Organs;

- Information module (14) - Taking (Photo) Pictures of Ionizing Radiation Source.

Dosimeter is the device intended for measuring ionizing radiation equivalent dose or dose rate detected by the device (and hence exposure of the device user to ionizing radiation) during a certain period of time, for example, during a period of staying in a certain territory or during a work shift.

Radiometer is the device intended for measuring ionizing radiation flux density for radiation inspection of suspicious items and assessment of radiation environment in a given place at given time.

The processor (1) includes the software for visual or audio or voice (with the help of alarms (4)) signaling about hourly, daily, weekly, monthly and annual tolerable, maximum permissible and intolerable ionizing radiation equivalent doses and dose rates as per the RF Radiation Safety Standard NRB 99/2009 and the Radiation Safety Standards and measurement units of other countries.

The keypad (5) has additional keys (not shown) for operating the device in the dose metering and/or radiation metering mode and also the keys for taking (photo) pictures of an ionizing radiation source and sending the taken pictures by e-mail, over Bluetooth or otherwise.

The dose metering, radiation metering and (photo) picture taking modes are set by the processor (1) software. The dose metering and radiation metering functions are performed by the counter (8) with the voltage multiplier (7), the interface unit (10), the amplifier (not shown) and all other components of the mobile communication device including the front-facing photographic camera, while (photo) pictures of an ionizing radiation source are taken with the help of the processor (1 ) and the mobile phone/ smartphone standard front- facing photographic camera (16). The counter (8), the voltage converter (multiplier) (7) and the interface unit ( 10) can be accommodated in the mobile communication device housing (17) or in the detachable enclosure (not shown).

Smartphone is the advanced version of a mobile phone with more powerful processor and with advanced personalization capabilities.

Thus, the combination of the interconnected and interacting devices (components) 1-10, 15 and 16 resulted in their integration and functional interrelation and led to creation of a new optimum design of the mobile communication devices with extended functional capabilities.

The mobile communication device with the dosimeter and the radiometer operates in the following manner.

The dose metering, radiation metering and (photo) picture taking modes are set by the processor (1) software. The dose metering and radiation metering functions are performed by the counter (8), the voltage converter (multiplier) (7), the interface unit (10) and all other components of the mobile communication device including the front-facing photographic camera, while (photo) pictures of an ionizing radiation source are taken with the help of the processor (1) and the mobile phone/ smartphone standard front-facing photographic camera (16).

The battery (6) or the mobile phone/smartphone standard audio jack or universal jack or mini-jack can be used for feeding electric power to the dosimeter and the radiometer as well as for transmitting control signals and also for measuring dose equivalent, dose rate and other parameters. The dosimeter and the radiometer are operated and data are exchanged via the digital protocol over the mobile phone/ smartphone audio-signal path by frequency or phase shift keying, or over the USB port in the universal or mini jack or over Bluetooth or over mobile phone/ smartphone NFC channel.

After the mobile communication device is turned on, the navigation device (9), the transceiver (15) and the counter (8) are activated. The navigation device (9) receives the GPS/GLONASS position information signals and records them in the memory (2). The mobile communication device is powered by the battery (6) and generally operates as normal mobile phone (smartphone) providing for telephone communication and various functions to its user.

The counter (8) operates as passive sensing element and can be turned on constantly or for a preset period of time. It serves for recording high energy (ionizing radiation) gamma, beta and alpha rays by detecting emission of secondary ionizing particles, photoelectrons or Compton electrons (the Compton effect).

When the counter (detector) (8) is turned on its wire serves as the anode and the tube acts as the cathode. The voltage multiplier (7) creates about 400-500V voltage between the cathode and the anode. The counter (8) operates on the principle of impact ionization and detects emission of secondary ionizing particles, photoelectrons or Compton electrons (the Compton effect).

If there is radiation in the surrounding environment, the radiation quanta emitted, for example, by a radioactive isotope strike the counter (8) walls and knock out electrons from the wall material. These electrons flow in gas, hit the gas atoms, knock electrons from the gas atoms and create positively charged ions and unbound electrons. The electric field between the cathode and anode accelerates the electrons that gain sufficient energy for impact ionization to occur. The ion avalanche is created and current flow through the counter (8) increases sharply. Thus, ionizing radiation and consequent emission of the Compton electrons along with application of high voltage to the counter (8) by the voltage amplifier (7) result in a crown discharge in the counter (8) gas medium. The discharge sends current through the counter and thus an ionizing radiation event is detected. As a result, a current and voltage pulse is generated and sent through the amplified and the interface unit (10) to the processor (1).

Therefore, the system consisting of the Geiger-Muller counter (8), the multiplier (7), the amplifier and the interface unit (10) cannot operate as an independent detector or radiometer.

The processor (1) counts number of dischargers in the counter (8) and has the software for visual or audio or voice (with the help of alarms (4)) signaling about hourly, daily, weekly, monthly and annual tolerable, maximum permissible and intolerable ionizing radiation equivalent doses. Thus, the counter (8) when exposed to ionizing radiation generates signals which are amplified by the amplifier, converted by the interface unit (10) and processed by the processor (1) with subsequent determination of hourly, daily, weekly, monthly and annual tolerable, maximum permissible and intolerable radiation dose and measurement of ionizing radiation background level (dose rate). After that, being displayed on the display (3) are the diagrams of human organs and systems condition depending on the ionizing radiation equivalent dose and current ionizing radiation background level (dose rate). This information is recorded in the memory (2). After that, these data are transmitted by the (Wi-Fi/GPRS) transceiver (15), for example, to the central data processing server of a mobile communication provider where the above data are accumulated, processed and disseminated, for example, to the members of Our Radioactive World Initiative. The members of Our Radioactive World Initiative are the owners of the DO-RA. Classic devices and the customers of the GPS/GLONASS service who are voluntary engaged in mapping territories and regions contaminated by radioactive (decay) products. The processor (1) includes the software for visual or audio or voice (with the help of alarms (4)) signaling about hourly, daily, weekly, monthly and annual tolerable, maximum permissible and intolerable ionizing radiation equivalent doses and dose rates as per the RF Radiation Safety Standard NRB 99/2009 and the Radiation Safety Standards and of other countries where DO-RA. Classic is used.

After turning the radio communication device on and pressing the appropriate keys on the keypad (5) being displayed on the display (3) are both visual messages regarding incoming SMS and missed calls and the aforementioned data about radioactive environment.

The audio alarms (4) inform the user on incoming radiofrequency signals received by the processor (1). If the threshold level has been achieved, the same audio alarms inform the user on hourly, daily, weekly, monthly and annual maximum permissible and/or intolerable ionizing radiation equivalent doses. Information about exposure dose (dose rate) is displayed on the display (3) in numeric expression in such units as, for example, mSv/h. These figures may be recalculated, corrected and displayed on the display (3) in the units of measurement used in the country of user residence. The navigation device (9) uses the GPS/GLONASS navigation aids (now shown) for locating position anywhere on the Earth.

The GPS/GLONASS navigation aids along with the navigation device (9) and the processor (1) display information on location of the radio communication device on the display (3).

The presented technical solution allows for implementing dose and radiation metering functions in mobile phones/ smartphones with the use of minimum number of built-in or detachable components which enable the radio communication device not just to provide for telephone communication but also to measure the ionizing radiation equivalent dose the device owner is exposed to as well as to measure background level (dose rate) in locations where measurements are taken. The relevance of this technical solution is determined by the fact that today a mobile phone/ smartphone has virtually become part of our body. During working hours we constantly have a mobile phone/ smartphone with us, and therefore the dose and radiation metering functions are seamlessly integrated with other functions of mobile phone/ smartphone significantly extending its functional capabilities.

When the mobile communication device operates in the dose metering mode the same components along with the special software module are used for performing the radiation metering functions for analyzing radiation environment. This mobile phone/ smartphone option allows the users to monitor "radiation cleanness" - not just measure dose rate at any territory but also control quality of food products, water and other everyday items - therefore protecting their health.

The GPS/GLONASS navigation option of mobile phone/ smartphone allows for automatically collecting objective information about radiation background level (dose rates) in locations where the owners of mobile phones/ smarphones are staying.

The mobile communication device operates in the Taking (Photo) Pictures of Ionizing Radiation Source mode (software module 4) in the following manner. Whenever the Radiometer software (software module 12) detects an ionizing radiation source and indicates its presence on the mobile phone/ smartphone display (3) it is possible to take (photo) picture of such source using the front-facing photographic camera. Besides that, it is also possible to additionally indicate the following parameters on the electronic picture: dose rate of the source which picture has been taken; time, day, month and year of this event; geographic coordinates of the radiation source. The photographic picture of the detected ionizing radiation source with the aforementioned parameters can be quickly sent by e-mail over the Internet, over Bluetooth or otherwise.

The utility model can be implemented in any mobile phone/ smartphone, where the dose and radiation metering functions are performed by the mobile phone/ smartphone components being the integral parts of DO-RA. Classic design. Specially developed DO-RA. Soft software packages and the operating system of a particular mobile phone/ smartphone provide for operation of DO-RA.
