Local measurement results of air radiation dose at a city hospital (updated on February 15, 2017)
Update date: February 15, 2017
We have measured the air radiation dose within the city hospital facility 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)).
Measurement results (implemented in FY2016)

【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.
