Description

Manufacturing method for displaying radiation by color change in real time {Production Method for Real Time Description System of Radiation by Color}

1 is a plan view of an apparatus for expressing radiation as a change in color in real time.

The present invention relates to a method for manufacturing a device in which radiation is expressed in real time as a change in color and the intensity of color changes in real time according to the intensity of the radiation dose.

Conventional radiation measuring apparatus is composed of a sensor, a signal processor, and a numerical display, and simply expressed the measured radiation dose numerically. In general, when the radiation dose is simply expressed by a numerical value, there is a disadvantage that a general person, not a radiation expert, cannot easily recognize whether radiation is generated.

Devices for measuring radiation include personal dosimeters which are worn on clothes immediately before performing radiation work to measure and assess the radiation exposure dose according to the work after work; The meter is in use.

The present invention provides a device capable of expressing radiation in real time as a change in color and displaying the intensity of color as a change in real time according to the intensity of the radiation dose so that the general public can easily identify whether radiation is generated. I would like to.

In order to solve this technical problem, in the present invention, alpha, beta, gamma rays, X-rays, neutrons measured by a device composed of several types of radiation sensors are represented in different colors, and the intensity of the color according to the intensity of the measured radiation dose To change.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The device for expressing the radiation designed in the present invention is composed of a radiation sensor unit, a signal processing unit, a color display unit.

The radiation sensor may use various sensors according to the type of radiation to be measured. In the case of the alpha ray sensor 1, an ionization box, a proportional counter tube, a liquid scintillation detector, etc., and the beta ray sensor 2, a liquid scintillation detector and a direct current An ionizer box, a proportional counter tube, a GM counter tube, and the like are used, and in the case of the gamma ray sensor 3 and the X-ray sensor 4, a NaI scintillation detector, a proportional counter tube, a semiconductor detector, an ion ionizer, and the like are used. In the case of the neutron sensor 5, a semiconductor detector, an ionization box, or the like is used.

The signal processor 6 is a color amplifier that represents the electrical signal obtained from the radiation sensor and is composed of a preamplifier, an amplifier, a signal converter, a memory device, and a signal processing line. That is, after the signal detected by the radiation sensor is processed by the signal processing unit through the signal processing line, the radiation dose value is displayed on the radiation dose numerical display panel 7 and the color display unit, and an alarm sound is emitted through the alarm speaker when necessary. .

The color display unit displays the radiation dose obtained by the signal processor 6 in color, and includes an alpha ray display lamp 8, a beta ray display lamp 9, a gamma ray display lamp 10, an X-ray display lamp 11, and a neutron display lamp. It consists of (12). The display lamp uses a light emitting diode (LED) that can represent various colors. The intensity change of color according to the radiation dose value measured from the radiation sensor is controlled by the LED itself programmatically to change the brightness from light color to dark color using one monochromatic LED for one kind of radiation and several monochromatic colors. After arranging the LEDs in a row, there is a method of raising the LEDs sequentially from the bottom up according to the intensity of the radiation.

The light used for the color display part can be used in various ways such as LED and incandescent lamp.

Hereinafter, an embodiment of a device manufacturing method in which radiation according to the present invention is expressed in real time as a change in color and the intensity of color changes in real time according to the intensity of the radiation dose.

Example 1

The radiation sensor used a semiconductor sensor to measure gamma rays. The signal processor consists of a pre-amplifier, an amplifier, an AD converter, and a numerical display panel that shows the radiation dose in graphs and figures. The communication port uses RS232, mobile phone and internet communication port, and the voltage is 110V and 220V freely. LED lamps use three types of high-brightness LEDs such as red, yellow, and green to indicate danger, caution, and safety, and ten LEDs for each color are used to program LEDs step by step according to the intensity of radiation. Made to turn on. According to the International Atomic Energy Standards, LEDs emit light when green is less than 1mSv / year, yellow is 1mSv / year to 20mSv / year, and red is more than 20mSv / year. For each color step, the green light indicates safety, and the LEDs emit light according to the signaled radiation intensity by dividing 0mSv / year to 1mSv / year into 10 levels. For example, five LEDs emit 0.5 mSv / year and nine green LEDs emit 0.9 mSv / year. In the case of yellow color indicating caution, the LED is emitted according to the signaled radiation intensity by dividing 1mSv / year to 20mSv / year in 10 steps. In the red color indicating danger, the LED is emitted according to the signaled radiation intensity by dividing 20mSv / year to 500mSv / year into 10 levels. In the red case, the alarm sounds at the same time. The color-expressing device was calibrated using a radiation source from 0.5mSv / h to 500mSv / h, and extrapolated below 0.5mSv / year.

The radiation sensor used a semiconductor sensor and an iontophoretic sensor to measure gamma rays and X-rays, respectively. The signal processor consists of a pre-amplifier, an amplifier, an AD converter, and a numerical display panel that shows the radiation dose in graphs and figures. The communication port uses RS232, mobile phone and internet communication port, and the voltage is 110V and 220V freely. For LED lamps, red LEDs were used for gamma rays and yellow LEDs were used for X-rays. Using 10 LEDs for each color, the LEDs are turned on step by step according to the intensity of radiation. The color change of each LED light is 1 for 0-0.1mSv / year, 2 for 0.1-0.5mSv / year, 3 for 0.5-1mSv / year and 1-5mSv / year according to the International Atomic Energy Standards. 4 for 5, 5-10mSv / year, 5 for 10-20mSv / year, 7 for 20-50mSv / year, 8 for 50-100mSv / year, 100-200mSv / year 9 and 200 mSv / year or more to emit light. When the measured radiation dose is more than 20mSv / year, the alarm sound was produced at the same time.
