We have conducted measurements of radiation levels in the air at the fire brigade station and community disaster prevention center facility in accordance with the city's air radiation measurement policy, and we would like to make the results public.
Furthermore, this measurement did not reveal any areas requiring cleaning or other measures (areas exceeding the standard value (0.23 microsieverts per hour)).

【explanation】
The annual equivalent of 0.23 microsieverts per hour is 0.99864 millisieverts, which is an indicator of the normal radiation dose received by the general public (less than 1 millisievert per year (natural radiation dose, etc.), as recommended by the International Commission on Radiological Protection (ICRP). )), this value is the city's criterion value .
According to the Ministry of the Environment's "Decontamination-related Guidelines," if the radiation dose at 1 meter of the ground surface is below 0.23 microsieverts per hour, no further action will be taken, but the city is on the safer side. We make decisions based on measurements taken at the closest location to the object (1 centimeter above the ground) while standing.
