The simulated experience providing device disclosed in Patent Document 1 stabilizes the training effect using virtual reality, and can realize the training effect by the simulated experience. However, it is not possible to imagine a contaminated area exposed to radiation or an area of use where radiation is used, and it is not possible to experience simulated radiation exposure in the contaminated area or area of use. Radiation is invisible to the human senses and cannot be sensed by the human senses, and is not painful to exposure. When working in contaminated areas exposed to radiation or in areas where radiation is used, various measures are being implemented with the aim of further reducing radiation exposure with the goal of minimizing the risk of radiation exposure. ..

However, the amount of exposure in the contaminated area or the area of use greatly increases or decreases depending on the work method, work time, distance from the radiation source, presence or absence of mockup, and the like. Therefore, exposure reduction education is carried out at any time based on the four principles of exposure reduction, "movement of radiation sources, shielding, distance, and time", but the reality is that it is not effective because it does not go beyond the accumulation of knowledge. .. It is well known that work in a nuclear power plant involves exposure. The exposure dose of workers is limited to 50 mSv / year or 100 mSv / 5 years, and reduction of exposure at the Fukushima Daiichi Nuclear Power Station, which is engaged in decommissioning work, is an urgent issue.

An object of the present invention is to be able to experience various operations and simulated radiation exposure in the virtual contaminated area or used area while imagining a contaminated area exposed to radiation or a used area where radiation is used, and to realize the exposure. The purpose is to provide an exposure experience simulation system that can be used. Another object of the present invention is to allow each exposed person to remember the radiation exposure by experiencing the pseudo-exposure of radiation, and to surely train each exposed person to reduce the radiation exposure. At the same time, it is to provide an exposure experience simulation system that can make the exposure experience person aware of the four principles of exposure reduction "movement, shielding, distance, and time of radiation sources" based on actual experience.

As another example of the present invention, a three-dimensional position includes a pseudo-shielding material assuming that the exposure experience simulation system is placed at an arbitrary position in the three-dimensional exposure virtual space and shields the radiation emitted from the pseudo-radiation source. The data identification means acquires the three-dimensional position data of the pseudo-shielding material in the first to nth exposure virtual space, and the exposure dose calculation means presumes that the radiation emitted from the pseudo-radiation source is shielded by the pseudo-shielding material. At the same time, the exposure dose estimated to have been exposed to the exposed person in the exposed virtual space specified by the exposed virtual space specifying means is calculated.

The exposure dose is calculated by multiplying the working time of the exposed person in the above and the reduction rate when it is estimated that the radiation is shielded by the pseudo-shielding material.

As another example of the present invention, the three-dimensional position data specifying means uses the LED lighting for the pseudo-shielding material installed on the pseudo-shielding material, and emits light of the LED lighting for the pseudo-shielding material from the image taken by the camera. Alternatively, the color development is received as a signal, and the three-dimensional position data of the pseudo-shielding material in the first to nth exposure virtual space is acquired from the received signal.

While acquiring the three-dimensional position data of the exposed person working in the space, the exposed virtual space that the exposed person worked for a predetermined time among the first to nth exposed virtual spaces is specified, and the exposed person is exposed in the specified exposed virtual space. Since the exposure dose (mSv) estimated to have been exposed by the experienced person is calculated and the calculated exposure dose (mSv) of the exposed person is output, the contaminated area exposed to radiation or the area of use using radiation is 3 While imagining as a dimensional exposure virtual space, it is possible to let the exposed person experience the pseudo-exposure of radiation in the virtual three-dimensional exposure virtual space (contaminated area or use area), and make each exposed person realize the radiation exposure. be able to. The exposure experience simulation system allows each exposed person to remember the radiation exposure by experiencing the pseudo-exposure of radiation in a three-dimensional exposure virtual space, and each exposed person can learn how to reduce radiation exposure. In addition to being able to learn reliably, the experiencer can be made aware of the four principles of radiation exposure reduction, "time / shielding, separation distance / movement of radiation source," based on actual experience. The exposure experience simulation system provides training on how to reduce exposure when each exposed person works in a three-dimensional exposed virtual space by changing the position and height according to each work content. It is possible to carry out various trainings based on the four principles of radiation exposure through the work procedure, tools used, and the presence or absence of mock-up meetings in the three-dimensional radiation exposure virtual space.

Using one or more cameras that capture the virtual space of three-dimensional exposure, the LED lighting for the pseudo-radioactive source installed in the pseudo-radioactive source, and the LED lighting for the exposure-experienced person installed in the exposed person. , The light emission or color development of the LED lighting for the pseudo-radioactive source and the LED lighting for the exposed person is received as a signal from the images taken by the camera, and the pseudo-radioactive source 3 in the first to nth exposure virtual space is received from the received signal. The experience simulation system that acquires the dimensional position data and the three-dimensional position data of the exposed person transmits a signal by the light emission of the LED lighting for the pseudo-radioactive source or the LED lighting for the exposed person, or the LED lighting for the pseudo-radioactive source or the exposure. A signal is transmitted by the color development of the LED lighting for the experience person (color change at regular intervals of three colors of red, green, and blue), and the pixel information of the camera is used as the data that is the source of positioning, so that the three-dimensional exposure is virtual. It is possible to realize high-precision and wide-range positioning in space, and to acquire accurate 3D position data of the pseudo-radioactive source in the 1st to nth exposure virtual spaces and accurate 3D position data of the exposed person. Can be done. The exposure experience simulation system acquires the accurate 3D position data of the pseudo-radioactive source in the 1st to nth exposure virtual spaces and the accurate 3D position data of the exposed person, and the acquired 3D position of the exposed person. Based on the data, the exposed virtual space where the exposed person worked for a predetermined time is specified, and the exposure dose (mSv) estimated to have been exposed by the exposed person in the specified exposed virtual space is calculated, so that the exposed person is exposed. It is possible to calculate the accurate exposure dose (mSv) that is estimated to have been achieved, and it is possible to make each exposure experience person feel the exposure to radiation with certainty.

Exposure by multiplying the exposure dose rate (mSv / h) for each 1st to nth exposure virtual space by the working time in the exposure virtual space where the exposure experience person in the 1st to nth exposure virtual spaces worked for a predetermined time. The exposure experience simulation system that calculates the dose (mSv) is one of the first to nth exposure virtual spaces, even if each exposure experience person works at different positions and heights in the three-dimensional exposure virtual space. It is possible to calculate the accurate exposure dose (mSv) in the exposed virtual space where the exposed person has worked for a predetermined time, and how to use the three-dimensional exposure virtual space while referring to the calculated exposure dose (mSv). It is possible to carry out training on whether or not radiation exposure can be reduced, and each person who has experienced radiation exposure can surely learn how to reduce radiation exposure.

The exposure dose (mSv) estimated to have been exposed by the exposed person was calculated for each exposed virtual space in the 1st to nth exposed virtual spaces worked by the exposed person, and each of the exposed virtual spaces worked by the exposed person. Exposure experience simulation that outputs the exposure dose rate (mSv / h) for each 1st to nth exposure virtual space and the exposure dose (mSv) for each 1st to nth exposure virtual space worked by the exposed person in chronological order. The system can know the dose rate (mSv / h) of each 1st to nth exposure virtual space and the dose change of the exposure dose (mSv) that changes with the passage of time in chronological order, and with the passage of time. It is possible to make each exposed person feel the changing exposure to radiation. The exposure experience simulation system knows the dose change of the exposure dose rate (mSv / h) and the exposure dose (mSv) that change with the passage of time for each 1st to nth exposure virtual space in time series. Since it is possible to make each exposed person feel the radiation exposure that changes with the passage of time, it is possible to make each exposed person remember the radiation exposure, and each exposed person can surely know how to reduce the radiation exposure. It is possible to surely make the exposed person aware of the four principles of radiation source movement, shielding, distance, and time based on actual experience.

When the exposure dose of the radiation exposed by the exposed person during the work of the exposed person in the 1st to nth exposure virtual space reaches the exposure limit value, a predetermined alarm notifying that the exposure dose has reached the exposure limit value. Alternatively, the exposure experience simulation system that sounds a predetermined message issues an alarm or message to notify the radiation exposure dose (mSv) when the radiation exposure dose (mSv) reaches the exposure limit while the exposure experience person is working in the three-dimensional exposure virtual space. Since it is pronounced, it is possible to know the approximate time until the radiation exposure dose (mSv) reaches the exposure limit, and it is possible to know the work contents and work procedures that can be performed within that time. It can be trained to be able to carry out the prescribed work within that time.

It was calculated while transmitting the calculated exposure dose (mSv) to the pseudo-dose meter, including a pseudo-dose meter that outputs the exposure dose of the exposed person who is possessed by the exposed person and works in the 1st to nth exposure virtual space. The exposure experience simulation system that outputs the exposure dose to the pseudo-dose meter is estimated to have been exposed to the exposed person when the exposed person performed a predetermined work in the three-dimensional exposure virtual space with the pseudo-dose meter in possession. Since the exposure dose (mSv) is output (displayed) to the pseudo-dose meter, the exposure experience person can know the exposure dose (mSv) that the accident was exposed to using the pseudo-dose meter, and radiation to each exposure experience person. You can definitely feel the exposure to radiation. The exposure experience simulation system can make each exposed person remember the radiation exposure by using a pseudo-dose meter, and each exposed person can surely learn how to reduce the radiation exposure, and in fact, Based on the experience, it is possible to surely make the exposed person aware of the four principles of exposure reduction, "movement of radiation source, shielding, distance, and time".

While presuming that the radiation emitted from the pseudo-radiation source was shielded by the pseudo-shielding material, the exposed virtual space that the exposed person worked for a predetermined time among the 1st to nth exposed virtual spaces was identified and specified. The exposure experience simulation system that calculates the estimated exposure dose (mSv) that the exposed person was exposed to in the exposed virtual space estimates that the radiation was shielded by the pseudo-shielding material, and does not use the pseudo-shielding material. The exposure dose (mSv) estimated to have been exposed by the exposed person is lower than that of the exposed person, and the exposure dose (mSv) when the exposed person uses the pseudo-shielding material and the exposure when the pseudo-shielding material is not used. It is possible to know the dose (mSv). The exposure experience simulation system can learn that it is possible to reduce the radiation exposure dose (mSv) that each exposure experience person is exposed to by using a shielding material (pseudo-shielding material), and each exposure experience. The person can know the necessity and importance of the shielding material.

The exposure dose rate (mSv / h) for each 1st to nth exposure virtual space is multiplied by the working time in the exposure virtual space in which the exposure experience person has worked for a predetermined time in the 1st to nth exposure virtual spaces. The exposure experience simulation system, which calculates the exposure dose (mSv) by multiplying the mitigation rate when it is estimated that the radiation was shielded by the pseudo-shielding material, estimates that the radiation was shielded by the pseudo-shielding material in the calculation of the exposure dose (mSv). The exposure dose (mSv) estimated to have been exposed by the exposed person was lower than that when the pseudo-shielding material was not used, because the reduction rate in the case of the exposure was taken into consideration, and the exposed person used the pseudo-shielding material. By knowing the exposure dose (mSv) in the case and the exposure dose (mSv) when the pseudo-shielding material is not used, the amount of radiation exposure to each exposure experience person by using the shielding material (pseudo-shielding material). It is possible to learn that it is possible to reduce (mSv), and each exposed person can know the necessity and importance of the shielding material.

The experience simulation system that acquires the three-dimensional position data of the pseudo-shielding material in the exposed virtual space transmits a signal by the light emission of the LED lighting for the pseudo radiation source and the LED lighting for the exposed person, or the LED lighting for the pseudo radiation source and the exposure. A signal is transmitted by the color development of the LED lighting for the experiencer (color change at regular intervals of three colors of red, green, and blue), and the pixel information of the camera is used as the data that is the source of positioning, so that the three-dimensional exposure is virtual.
