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: microsievert per hour) |
|---|---|---|---|---|
| 1 cm above ground | ||||
| welfare center | 2016 June 15th |
rain | Rain gutter (2nd floor roof) | 0.060 |
| Gutter (next to the storage room on the 1st floor) | 0.072 | |||
| Rain gutter (next to the emergency exit on the first floor) | 0.092 | |||
| In front of the entrance | 0.090 | |||
| Rain gutter (in front of bicycle parking lot) | 0.104 |
【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.
