At district halls, etc., we measured air radiation dose based on the city's air radiation dose measurement response policy, so we will announce the results.
In addition, in this measurement, there were no places that required cleaning, etc. (places exceeding the judgment standard value (0.23 microsieverts per hour)).

【explanation】
When converted from 0.23 microsieverts per hour to 0.99864 millisieverts per year, it is lower than the radiation dose index (1 millisievert or less per year (excluding natural radiation dose, etc.)) recommended by the International Commission on Radiological Protection (ICRP) for ordinary people to receive.
According to the Ministry of the Environment's "Decontamination Guidelines", if the radiation dose at 1 meter above the ground is below 0.23 microsieverts per hour, no further action will be taken.
