We have measured the air radiation dose within the welfare center facility based on the city's air radiation dose 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)).
| Name of facility | measuring date | weather | Measurement location | Measured value (unit: microsieverts per hour) |
|---|---|---|---|---|
| 1 centimeter on the ground | ||||
| Welfare center | 2016 June 15th |
rain | Rain gutter (2nd floor rooftop) | 0.060 |
| Gutter (next to the storeroom on the 1st floor) | 0.072 | |||
| Rain gutters (next to the emergency exit on the 1st floor) | 0.092 | |||
| in front of the entrance | 0.090 | |||
| Rain gutter (in front of bicycle parking lot) | 0.104 |
【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.
