When the radioactive material leaked in the accident of the nuclear power plant, quickly as was standing a prospect in the practical application of a small device capable of exposure measurement of the thyroid gland, the Nuclear Regulatory Commission of the measurement system using the device from this month It is a policy to start consideration.
When radioactive iodine leaked from a nuclear accident is taken in, it gathers in the thyroid gland near the throat and is exposed, increasing the risk of cancer. Therefore, in the event of an accident, quick and accurate exposure measurement is required.
However, in the accident at the Fukushima Daiichi nuclear power plant 10 years ago, the measuring device was heavy and difficult to carry, and it was also affected by the high radiation around it, which hindered the measurement.
For this reason the Nuclear Regulatory Commission, such as promoting the improvement of the measuring device Japan Atomic Energy Agency, recently, small in size and can carry, that with a prospect to practical use in the vicinity of the radiation is also capable of blocking devices I made it clear.
Based on this, the Regulatory Commission plans to start studying a system for promptly measuring thyroid exposure from this month, and plans to put together a concrete system such as the division of roles between local governments and the national government over a three-month period.
A person in charge of the Regulatory Commission said, "Until now, the system for measuring thyroid exposure was not sufficiently in place, but we can finally consider a practical system by improving the device. We would like to proceed with discussions as soon as possible."
