Space radiation dose local measurement result (April 1, 2017 update) of Cultural Center
Updated: April 1, 2017
We have measured the air radiation dose within the cultural center facility based on the city's air radiation dose measurement response policy, and we would like to announce the results.
In addition, during this measurement, there were no locations that required cleaning, etc. (locations that exceeded the judgment standard value (0.23 microsieverts per hour)).
Note: For information on the attached children's hall and after-school club, please refer to " Results of local measurement of air radiation dose at children's hall and after-school club ."

【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.
