Spatial radiation dose local measurement results of children's houses and after-school clubs (updated on February 1, 2017)

We have measured air radiation doses based on the city's air radiation dose measurement response policy in the facilities of the children's center and after-school club, so we will publish the results.
In addition, in this measurement, there were no places that required cleaning, etc. (places exceeding the judgment standard value (0.23 microsieverts per hour)).

Note: The Daini Elementary School After-School Club shares the entrance and exit with Inagi Daini Elementary School, so please refer to " Results of Local Air Radiation Measurement Results for Municipal Elementary and Junior High Schools ."

【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).
