At the Hirao branch office, we have measured the air radiation dose based on the city 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: Regarding the Wakabadai branch office, please refer to " Local measurement results of spatial radiation dose at the Cultural Center " (i-Plaza).
| Name of facility | measuring date | weather | Measurement location | Measured value (unit: microsievert per hour) |
|---|---|---|---|---|
| 1 cm above ground | ||||
| Hirao Branch | 2016 July 5th |
cloudy | Under the rain gutter on the east side | 0.067 |
| Under the rain gutter on the west side | 0.083 | |||
| Under the public relations board | 0.092 |
【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.
