Eye lens exposure limit reduced to one-third of conventional level at 2:27 on February 29
Exposure of the eyes to large amounts of radiation may cause cataracts, which the NRA reviewed the limits of exposure and reduced it to 50 mSv per annum from April next year. I'm going to.
There is a known risk of cataracts that cause the eyes in the eyes to become cloudy when exposed to large amounts of radiation, but an international group of experts has recommended that countries review their standards strictly.
The Nuclear Regulatory Commission, which was considering this, decided to change the limit of lens exposure this month, reducing the current annual dose of 150 mSv to one third of 50 mSv per year. I did it.
Eyes are often exposed at medical sites that use radiation, such as x-rays.
After reviewing relevant laws and regulations, the standards will be reduced from April next year.
