In facilities where there is a possibility of constant exposure to radiation sources, such as nuclear power plants, the development of radiation source location detection technology that can monitor radiation sources and detect exposure is required for the safety of workers.

The radiation source measurement equipment that has been used previously is mainly a Compton camera type that determines the location of the gamma ray source, or an imaging equipment that detects and measures the radiation source using a coding aperture.

These conventional devices are large in size and have many limitations when used while moving.

Therefore, there is a need for the development of portable radiation measurement and detection equipment that minimizes the size and is easy to carry for nuclear power plant workers.

To elaborate, social interest in radiation has increased in Korea since the Fukushima nuclear accident in 2011 and the radon bed scandal in 2018.

In particular, since radiation has characteristics that cannot be felt by the five human senses, the demand for the development of a system that can accurately measure and analyze the radiation and radioactivity of areas and objects contaminated with radioactive materials has grown rapidly to relieve anxiety about this. It is increasing.

In addition, with the development of radiation application technology, the demand for the use of radiation continues to increase, and in relation to this, the demand for the safe use of radiation is also increasing.

In particular, methods for finding unknown or lost radiation sources in places where radiation is regularly used have been steadily developed, but despite these efforts, finding unknown radiation sources still requires a lot of time and effort.

1. Republic of Korea Patent Registration No. 10-2182318 (registered on November 18, 2020)

The present invention is intended to solve the above-mentioned problems, and its technical gist is to allow the radiation measurement sensing module to be linked with Google Glass, but the radiation measurement sensing module is manufactured in the form of a small portable box so that it can be used by workers in nuclear power plants or radiation-contaminated areas.

As much as possible, a boron polyethylene (Boron PE) mask 111 of the same pattern is added to the front end of the tungsten mask pattern of the coding aperture to ensure neutron shielding.

At this time, it is preferable that Google Glass 30 uses a 2D camera method.

In addition, the wireless communication means of the present invention is 3G, 4G, 5G, 3GPP (3rd Generation Partnership Project), 5GPP (5th Generation Partnership Project), LTE (Long Term Evolution), WIMAX (World Interoperability for Microwave Access), and Wi-Fi (WiFi). -Fi), Internet, LAN (Local Area Network), Wireless LAN (Wireless Local Area Network), WAN (Wide Area Network), PAN (Personal Area Network), RF (Radio Frequency), Bluetooth network , it is desirable to use one or more of a Near-Field Communication (NFC) network, a satellite broadcasting network, an analog broadcasting network, and a Digital Multimedia Broadcasting (DMB) network.

Next, the present invention will be described in more detail with reference to the attached drawings.

First, as shown in FIGS. 1 and 2, the present invention is configured so that a radiation measurement sensing module 20 and Google Glass 30 are mounted on a safety helmet 10.

Accordingly, the sensing module 20 and Google Glass 30 are interconnected with data transmission through wireless communication means (GPS, Wifi, Bluetooth, network communication network, commercial wireless communication, etc.) and applications, allowing the sensing module 20 to When the contamination or distribution of the radiation measurement target area is measured, it is output to Google Glass (30).

To elaborate, workers entering facilities such as Korea Hydro & Nuclear Power or nuclear power plants are required to wear safety helmets.

Typically, workers bring a personal dosimeter to work. The dosimeter is simply a tool to measure radiation dose, and even if the worker is exposed, he or she works without knowing where he or she received it or which part is dangerous.

The present invention is intended to solve this problem, by mounting a miniaturized portable radiation measurement equipment (sensing module for radiation measurement of an encoded aperture-based radiation (gamma ray and double particle) image fusion device) on a hard hat, and linking it with Google Glass to detect the radiation source. It is characterized by showing where it is on the screen through Google Glass.

For reference, the coding aperture-based radiation (gamma ray and double particle) image fusion device of the present invention is manufactured for the purpose of miniaturization, and the existing mask uses a 3D printer to assemble tungsten or lead in the form of a slot, but the present invention Miniaturization is achieved by producing a tungsten mask (which itself becomes a mold) with a 3D printer.

In other words, the integrated tungsten mask achieves miniaturization as the sensor module enters the inside through the rear opening.

In contrast, conventionally, a shielding material to block background radiation is added to the side to build up the exterior, but this additional structure hinders the realization of miniaturization.

Accordingly, the sensing module 20 for radiation measurement is an encoding aperture-based radiation (gamma ray and double particle) image fusion device, and includes an optical camera 100, an encoding aperture 110, a scintillator array 125, and an optical sensor array 130. , includes a signal processing unit 140, an image fusion unit 150, and a display 180, and additionally includes a battery 160, a cooling fan 170, and a GPS (not shown) that provides real-time location information of the radiation source. As much as possible, a boron polyethylene (Boron PE) mask 111 of the same pattern is added to the front end of the tungsten mask pattern of the coding aperture to ensure neutron shielding.

For reference, the sensing module 20 for measuring radiation of the present invention has already been described in a prior document (Patent No. 10-2389288: registered on April 18, 2022) for which the applicant of the present application has previously applied and registered, and this is also used in the present invention. Apply and explain.

First, the sensing module 20 for measuring radiation of the present invention is also a neutron shielding encoding aperture by adding a boron polyethylene (Boron PE) mask of the same pattern to the front end of the tungsten mask pattern of the encoding aperture.

Figure 3 is a table analyzing the shielding ability of tungsten and boron polyethylene (Boron PE) against thermal neutrons.

As can be seen in the table, tungsten is not suitable for shielding neutrons, and boron polyethylene (Boron PE) shows high shielding ability for neutrons and can show sufficient performance even at a thin thickness.

The encoding aperture (110) part of the encoding aperture imaging device is a mosaic pattern made of tungsten and is made up of small square pillars to create a mask pattern.

By adding a square-pillar mask 111 made of boron polyethylene (Boron PE) to the front of these small square pillars, the effect of shielding both gamma rays and neutrons can be expected.

The length of the shielding body made of boron polyethylene (Boron PE) is approximately 1 to 8 mm, and can be applied to the design as long as it does not harm the shape or size of the existing imaging device.

Figure 4 is a diagram schematically showing the configuration of an encoding aperture-based radiation (gamma ray and double particle) image fusion device according to an embodiment of the present invention.

The encoding aperture-based radiation (gamma ray and double particle) image fusion device according to an embodiment of the present invention largely includes an optical camera 100, an encoding aperture 110, a scintillator array 125, an optical sensor array 130, and a signal processing unit. It is configured to include (140), an image fusion unit (150), and a display (180).

Additionally, in an additional embodiment, it may further include a battery 160, a cooling fan 170, and a GPS (not shown) that provides real-time location information of the radiation source.

First, the optical camera 100 is a CCD or CMOS image sensor that acquires on-site images by photographing the site of the radiation source.

The optical camera 100 captures images to be fused with gamma ray and neutron images in which the reaction positions of radioactive materials are processed into images through the operation program software of the image fusion unit 150, which will be described later. Images can be realized even in low lighting. It is adjusted so that

The encoding aperture 110 receives radiation emitted from a radiation source, and an encoded pattern is applied.

The encoding aperture 110 is a mechanical focusing device that blocks high-energy radiation from entering from an unwanted direction, and the material is tungsten.

This encoded aperture 110 is manufactured in the form of an encoded pattern mask to react with the scintillator array 125, which will be described later, and at this time, the encoded pattern is applied as a MURA pattern.

The mask pattern of the encoding aperture 110 may be any one of a mosaicked pattern, a centered mosaick pattern, and an antisymmetric MURA pattern, and this structure is an additional layer of the mask pattern. It has the advantage of being able to reconstruct a real-time radiation incident image at once without going through a process (e.g., rotation of the mask pattern, etc.).

The pattern structure of the mask pattern is such that a pair of pattern areas arranged in a diagonal area based on the center are symmetrical to each other. Based on two virtual diagonals passing through the center point of the center area, a pair of pattern areas are arranged on a virtual diagonal in the center area. Each area pattern is arranged in a structure that is symmetrical to each other.

This arrangement structure can accurately extract image information without taking more than two shots due to the symmetry of the pattern, and has the advantage of increasing the signal-to-noise ratio (removing noise) by realizing the same image without rotating the mask. have it

The scintillator array 125 has an NxN array of pixels and serves to generate scintillation signals for gamma rays and neutrons from radiation incident through the encoding aperture 110.

More specifically, the scintillator array 125 reacts with the audit rays and neutrons that pass through the encoding aperture 110 to generate a fine flash signal of light, and includes a scintillator body 120 formed as an array of one or more pixels, and a scintillator body. It is composed of a shielding body 121 made of a square ring-shaped tungsten material that shields both the upper, lower, and left and right sides of the unit 120, and takes advantage of the fact that the energy regions of the reaction energy spectrum between neutrons and gamma rays are different from each other. .

This scintillator body 121 is a pixel type liquid scintillator to which waveform discrimination (PSD) is applied, a plastic scintillator, a stilbene (1, 2-diphenylethylene, C14H12) scintillator, and a CLYC (Cs2LiYCl6:Ce) scintillator. , Organic Glass Scintillator can be applied.

In particular, when the scintillator body 120 is a stilbene organic scintillator, it also has the advantage of being able to obtain heterogeneous images in which neutrons and gamma rays are separated.

The optical sensor array 130 has an NxN array of pixels and serves to obtain an electrical signal for the scintillation signal generated through the scintillator array 125.

More specifically, the optical sensor array 130 serves to convert the scintillation signal converted into light in the scintillator array 125 into a fine electrical signal depending on the amount of light. At this time, the optical sensor array 130 is a silicon optoelectronic signal. An array-type semiconductor optical sensor corresponding to a multiplier (SiPM) or a pixel-type position-sensitive photomultiplier (PSPMT) can be applied.

In particular, in the case of SiPM, one-to-one coupling is possible with a small scintillator with a cross-sectional area of several mm2, so it has the advantage of maximizing the light receiving performance of collecting light emitted from the scintillator array 125.

In addition, as the optical sensor array 130 is accommodated in the shielding body 121 included in the scintillator array 125, both the upper and lower sides and the left and right sides can be shielded from radiation, similar to the scintillator body portion 120.

For reference, Figure 5(a) is a diagram showing the configuration of the coding aperture of an existing imaging device, and Figure 5(b) is a diagram showing the shape of the neutron shielding coding aperture of the present invention.

And Figure 6(a) shows a tungsten side shield that shields the top, bottom, and left and right sides of the existing optical sensor array 120, and Figure 6(b) shows a boron polyethylene (Boron PE) shield for background radiation shielding on the back of the present invention. This is a drawing showing the added shape.

In the present invention, a boron polyethylene (Boron PE) side shield 121 is added to the outside of the tungsten that shields the top, bottom, and left and right sides of the optical sensor array, and a boron polyethylene (Boron PE) side shield 121 is added behind the tungsten shielding plate that is responsible for shielding the background radiation at the rear. PE) shielding body (133) was added.

Figure 7 is a diagram showing a radiation (gamma ray and double particle) image fusion device in which boron polyethylene (Boron PE) is added to the encoding aperture, the top, bottom, left, right, and rear sides of the optical sensor array, respectively.

The drawing of the neutron shielding encoding aperture of the present invention and the radiation (gamma ray and double particle) image fusion device using the same shows the front mosaic pattern portion, the top, bottom, and left and right sides of the optical sensor array behind the encoding aperture, and the rear portion of the device using boron polyethylene (Boron PE). ) is added, and has the feature of adding neutron shielding throughout the imaging device.

The signal processing unit 140 serves to distinguish reaction signals for the reaction location and reaction size of gamma rays and neutrons, based on the electrical signal acquired through the optical sensor array 130. This signal processing unit 140 extracts the size, position, and PSD value of the signal for each pixel obtained through the optical sensor array 130.

The image fusion unit 150 records reaction images of each gamma ray and neutron based on the reaction signal of the signal processing unit 140, and then records the reaction image of each gamma ray and neutron and the scene of the radiation source acquired through the optical camera 100. It functions to obtain a fused image by fusing the images.

At this time, the image fusion unit 150 acquires, stores, and analyzes gamma-ray image and neutron image data using a software program, acquires, stores, and analyzes gamma-ray and neutron spectra, and acquires, stores, and analyzes information by time and radiation dose. It also corresponds to a type of computer that stores programmed software that calculates the reaction positions of gamma rays and neutrons and edits them into images.

It allows reconstruction of on-site images in real time, and the algorithm for this reconstruction uses iterative image reconstruction algorithms such as MLEM and Compressed-sensing, and the system functions required for this are simulation experiments such as MCNP and GEANT4. It is produced using code, or a system function obtained by applying mathematical modeling is used.

At this time, to reconstruct the image in real time, the minimum number of iterations and reconstruction time must be used and previous information must be initialized. Reconstruction time means the minimum time to obtain at least 100 pieces of information.

Meanwhile, there are two major methods for reconstruction by fusing gamma-ray images, neutron images, and field images in the image fusion unit 150.

Firstly, an integration mode that sets the total detection time and uses all signals detected during that time, and secondly, only during the time when the total number of detected signals reaches 3000 using the count rate information in the GUI. It is a real-time mode that accumulates and uses the detector map information at that time in the image reconstruction technique mentioned above.

For example, an image of a radiation source can be reconstructed using an image reconstruction technique with only 3000 detection signals. If the count rate from the radiation source is 300 cps (counts per second), events are recorded for 10 seconds and a map of the detector is created. Next, the image is reconstructed, and at this time, there is a display on the GUI that shows the progress rate of 100%, so you can predict when the radiology image will be displayed.

The display 180 serves to output image data, energy spectrum, count rate, and temperature values processed through the image fusion unit 150.

At this time, the present invention obtains real-time location information of the radiation source through GPS and outputs it on the screen through the display 180.

In addition, in the present invention, power can be supplied to the entire coding aperture-based radiation (gamma ray and double particle) image fusion device through the battery 160. In this case, the battery 160 may be a rechargeable secondary battery, and in another embodiment In this case, the battery 160 may be connected to an external power cable to directly receive power.

Additionally, in the present invention, a cooling fan 170 may be provided to radiate and cool heat generated during the data processing of the signal processing unit 140 and the image fusion unit 150 to the outside.

In addition, as a shield made of tungsten is provided between the optical sensor array 130 and the signal processing unit 140, background radiation emitted from the rear of the signal processing unit 130 toward the optical sensor array 130 is shielded. This has the advantage of being able to obtain more accurate data.

As seen, through the above-described configuration of the present invention, the present invention visualizes information such as the location of radiation fused with the actual site image, dose per second, nuclide discrimination through spectral information, and site location through GPS information, so that the operator can It has the advantage of being able to create a radiation distribution map according to location movement by promoting safety and making it easy to carry.

At this time, it is preferable that Google Glass 30 uses a 2D camera method.

In addition, the wireless communication means of the present invention is 3G, 4G, 5G, 3GPP (3rd Generation Partnership Project), 5GPP (5th Generation Partnership Project), LTE (Long Term Evolution), WIMAX (World Interoperability for Microwave Access), and Wi-Fi (WiFi). -Fi), Internet, LAN (Local Area Network), Wireless LAN (Wireless Local Area Network), WAN (Wide Area Network), PAN (Personal Area Network), RF (Radio Frequency), Bluetooth network , it is desirable to use one or more of a Near-Field Communication (NFC) network, a satellite broadcasting network, an analog broadcasting network, and a Digital Multimedia Broadcasting (DMB) network.

In addition, it is preferable that the sensing module for measuring radiation is mounted using the one-touch mounting hole 50 when mounted on a safety helmet.

Accordingly, the one-touch mounting device 50 is largely composed of a holder 51 and a support bracket 52, as shown in FIGS. 8 to 11.

At this time, the holder 51 is in the form of a clip with one end open, and a wedge-shaped hook is provided on the open end side, so that a sensing module for radiation measurement in the form of a square block or box can be clamped (compressed by upper and lower elasticity) and fixed. It is formed so that

Accordingly, an insertion ring 55 for fitting is provided at the other end of the holder (the partition side), and a plurality of stoppers 56 and a locking protrusion 57 are provided on the outer peripheral surface of the insertion ring 55 at set intervals and steps. It is formed to be provided, and the stopper 56 has an inclined surface 56-1 in an uphill shape along one rotation direction, and when inserted into the insertion hole 53 of the support bracket, the hemispherical protrusion 54 formed on the inner peripheral surface of the insertion hole is formed. It is formed to be tightly fixed to the hemispherical surface.

At this time, an arc-shaped or hemispherical mounting groove 56-2 is formed on the high-top height side of the section of the inclined surface 56-1, so that the hemispherical surface of the hemispherical protrusion 54 corresponds to it, preventing over-rotation in the circumferential direction and one-touch insertion. It is formed to be joined in a way (stored at the highest height and then pressed together).

At this time, the locking protrusion 57 is disposed in a direction perpendicular to the stopper (approximately 90°) or protrudes at an angle spaced apart from the stopper by a set angle, and is formed to have a diagonal cross-section with an opening in one direction.

The long side of this locking protrusion (the long side that connects the short legs in the form of a digger) enters the bottom (or side end) of the hemispheric protrusion with the rotation of the insertion ring, and is formed to prevent the insertion ring inserted into the insertion hole from falling outward.

In other words, the one-touch mounting device 50 of the present invention is composed of a holder 51 and a support bracket 52, and the insertion ring of the holder corresponds to the insertion hole of the support bracket and is assembled by fitting, and the insertion ring is attached to the outer peripheral surface. A stopper and a locking protrusion are formed to correspond to the hemispherical protrusion of the insertion hole, and when rotating, the hemispherical surface of the hemispherical protrusion is pressed and fastened in the form of male and female protrusions through the inclined surface of the stopper and the mounting groove. It is formed to be caught on one end (inner end) of the hemispherical protrusion so that it does not separate from each other in the assembled state. (Conversely, it is formed to be released when rotated in reverse).

This is to ensure quick assembly and fastening, easy workability, and high fastening reliability.
