Description
When converted to an annual basis, 0.23 microsieverts per hour amounts to 0.99864 millisieverts, which is below the standard for normal radiation exposure for the general public (less than 1 millisievert per year, excluding natural background radiation) as recommended by the International Commission on Radiological Protection (ICRP). Therefore, this value is used as the city's judgment criterion.
According to the Ministry of the Environment's "Decontamination Guidelines," if the radiation level at 1 meter above the ground is below 0.23 microsieverts per hour, no further action is required. However, our city takes a more cautious approach and makes decisions based on measurement results taken at the closest point to the object (1 centimeter above the ground).
