Spatial radiation dose local measurement result of infant childcare facility (January 1, 2017 update)

Last updated: January 1, 2017

We have measured the air radiation dose within the infant childcare 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)).
Since FY2015, we have been measuring at Shiroyama Nursery School Minamiyama, Hongo Yuushi Nursery School (formerly Daini Nursery School), and a certified children's school (Children's Forest Child Care Center).

【explanation】
When converted from 0.23 microsieverts per hour to 0.99864 millisieverts per year, the International Commission on Radiological Protection (ICRP) recommends that the normal dose of radiation received by ordinary people (below 1 millisievert per year (natural radiation dose, etc.) (Excluding)), so this value is the city's judgment standard value .
According to the Ministry of the Environment's "Decontamination Guidelines", if the radiation dose at 1 meter of the ground is below 0.23 microsieverts per hour, no further action will be taken. , the response is determined based on the measurement results at the point closest to the object (1 cm on the ground surface).
