Therefore, there is a limit to the error depending on the distance and the measurable range. In addition, conventional radiation measuring instruments have a bulky size and are inconvenient to carry. Particularly, since the measuring person carries the radiation measuring equipment by carrying it, there is a disadvantage that the radiation exposure amount increases as the radiation leakage point gets closer to the radiation leakage point.

To overcome this disadvantage, a remote control radiation measuring system using wireless communication (Korean Patent Laid-Open Publication No. 10-1999-0069100) has been proposed as a prior art. According to the related art, the telemetry device measures the amount of radiation dose and transmits it as a countable pulse signal at the receiver. However, in the system using such a wireless communication, there is a problem that the radiation measurement device should be placed at a place to be measured. I can not. In particular, if the place for measuring radiation is underwater, such a problem can not be solved, and a method for detection of underwater radiation is required.

1 is a schematic diagram of an underwater radiation detection system using a mobile device of the present invention.

1, the underwater radiation detection system 100 includes a radiation detection device 110 and a mobile device 120. [

The radiation detection apparatus 110 detects radiation in water, converts the detected radiation dose into a radio signal, and sends it to the mobile device 120.

The mobile device 120 receives the radiation dose signal transmitted from the radiation detection apparatus 110 and determines the degree of contamination of the radiation in the water. The mobile device 120 includes an electronic device having a wireless communication means such as a smartphone tablet PC and a notebook computer. According to an embodiment, the mobile device 120 may interpret the radiation dose signal transmitted from the radiation detection device 110 A program for judging the degree of radiation contamination in the water may be included.

2, each component of the radiation detection apparatus 110 will be described in detail.

2 is a block diagram of a radiation detection apparatus 110 according to an embodiment of the present invention.

According to one embodiment, the radiation detection apparatus 110 includes a radiation detection unit 111, a signal conversion unit 112, a communication processing unit 113, a built-in power supply 114, and a waterproof packing 115.

The radiation detecting unit 111 includes a scintillator 111a that emits light by receiving radiation, a semiconductor detector 111b that detects light generated from the scintillator, an amplification unit 111c that amplifies the signal detected by the semiconductor detector 111b, And a signal processing unit 111d for processing the amplified signal in the amplification unit 111c.

The scintillator 111a is a material that emits light by receiving radiation, and may be composed of different kinds depending on the kind of radiation to be detected. That is, the scintillator 111a may be constituted by packaging a substance for detecting? -Ray, a substance for detecting? -Ray, a scintillator for? -Ray detection, and a substance for detecting?, Respectively.

Although the scintillator 111a is shown as a bundle type in terms of α, β, γ, and χ, the scintillator 111a is formed of a material for detecting α-rays, β-rays, γ-rays, A scintillator including a material for? -Ray detection, a scintillator including a material for? -Ray detection, and a material for? -Lens detection And that the included scintillators can be replaced as needed.

In other words, when the radiation detecting apparatus 110 is used for the purpose of detecting an alpha rays, the scintillator 111a of the radiation detecting unit 111 may be equipped with a kind including a material for detecting an alpha ray, When the apparatus 110 is used for detecting the x-ray, the scintillator 111a of the radiation detecting unit 111 may be equipped with a kind including material for detecting the x-ray.

On the other hand, the scintillator 111a may be formed in a structure including a reflector for preventing leakage of detection light to more effectively detect light emitted from the radiation detecting material. A Teflon reflector may be used as the reflector.

The semiconductor detector 111b detects light emitted from the radiation detecting material. The semiconductor detector 111b may comprise a silicon light doubling device for sensing weak light.

According to the embodiment, the scintillator 111a and the semiconductor detector 111b may be composed of a single packaged module, and the scintillator 111a and the semiconductor detector 111b may be separately detachable. That is, the semiconductor detector 111b may be configured to be separated from the scintillator 111a.

The amplifying unit 111c amplifies the signal detected by the semiconductor detector 111b. According to the embodiment, the amplification unit 111c amplifies the small radiation detection signal detected by the semiconductor detector 111b to 2V or more.

The signal processing unit 111d processes the amplified signal from the amplification unit 111c. The signal amplified by the amplifier 111c includes analog noise due to dark current or the like. Therefore, the signal processor 111d filters the signal amplified by the amplifier 111c to remove the analog noise.

The signal converting unit 112 includes an analog-to-digital converter 112a (hereinafter referred to as ADC) and a noise filter 112b.

The ADC 112a converts the no-log noise canceled signal from the signal processing unit 111d into a digital signal. The noise filter 112b removes the digital noise included in the digital signal.

Although the amplification unit 111c, the signal processing unit 111d, the ADC 112a and the noise filter 112b are described as independent components according to the above description, the amplification unit 111c, the signal processing unit 111d 111d, the ADC 112a, and the noise filter 112b may be implemented as a single packaged device.

The communication processing unit 113 includes a dose processing unit 113a and a wireless communication control unit 113b.

The dose processing unit 113a receives a signal that detects the amount of radiation from the noise filter 112b, and counts the amount of radiation. That is, the detected radiation dose is numerically expressed.

The wireless communication controller 113b converts the quantified radiation dose into a wireless signal and sends it to the mobile device 120. [ The wireless signal transmitted at this time can be performed by the Bluetooth communication method. The reason for using the Bluetooth communication method is to miniaturize the communication processing unit 113 using a conventional commercial communication method, and the radio signal transmission method according to the present invention is not limited to this.

For example, since the attenuation rate of radio waves is high in water, a radio transmission system using visible light blinking as a radio signal may be used.

The built-in power supply 114 supplies power to the radiation detection apparatus 110.

The waterproof packing 115 packs the radiation detection unit 111, the signal conversion unit 112, the communication processing unit 113 and the built-in power supply 114 so that the radiation detection apparatus 110 can be used in water. The scintillator 111a may be waterproof and packed separately from the waterproof packing 115 so that the scintillator 111a can be detachably coupled according to the radiation source to be measured.

3 is a schematic diagram illustrating an example in which a radiation detection apparatus according to an embodiment of the present invention detects radiation in water and transmits a signal to a mobile device.

As shown in FIG. 3, since the radiation detection apparatus 110 is waterproof and packaged, the radiation dose can be measured in the vicinity of a source of radiation (object to be radiation-detected) in water. In addition, since the radiation dose value measured by radio is sent to the mobile device 120, it is possible to reduce the risk of exposure of the measurer.

Although the disclosed method and apparatus have been described with reference to the embodiments shown in the drawings for the sake of understanding, those skilled in the art will appreciate that various modifications and equivalent embodiments are possible without departing from the scope of the present invention. I will understand that. Accordingly, the true scope of protection of the disclosed technology should be determined by the appended claims.
