Radiation levels exceeding the government-set safety limit of 0.23 microsieverts per hour have been detected on the grounds of five schools in the city of Kashiwa, Chiba Prefecture, the prefectural board of education said Monday.

Between late April and mid-May, the board officials detected radiation levels of up to 0.72 microsieverts per hour in certain areas of the schools, including Kashiwa High School and Kashiwa Chuo High School. The areas — including soil near a school swimming pool and drainage gutters — are not frequented by students, but the board closed them off and will work to quickly decontaminate them, the officials said.

Kashiwa has been one of the areas with high radiation readings since the 2011 nuclear disaster at Tokyo Electric Power Company Holdings Inc.’s Fukushima No. 1 power plant.

According to NHK, the board of education had been checking the soil on the school premises in Kashiwa after radiation levels beyond the state limit were detected in shrubbery near the city’s public gymnasium. The board will announce the results of radiation tests at other schools in the prefecture around the end of July, NHK reported.

In January 2017, the Chiba Prefectural Board of Education was notified that radiation above the national standard level was measured at the Kashiwa city central gymnasium.

Following that report the Chiba Prefectural Board of Education conducted an investigation in Kashiwa city from late April to the middle of May 2017.

A radiation level exceeding the national standard of 0.23 microsievert per hour was detected on the premises of five schools in Kashiwa City, The radiation measured at 1 meter above ground level ranged from 0.24 to 0.72 microsievert.

At Kashiwa High School, Higashi Tsukuba High School and Middle School, Kashiwa Chuo High School, Kashiwanami High School and Kusanami Takayanagi High School, at places where usually no one enters: near a pool, at the back of a bicycle parking lot, etc..

The prefectural Board of Education decided to cordon those hot spots, to prohibit the entry and to decontaminate those places by soil removal.

They are also planning to conduct a radiation levels survey to the schools outside of Kashiwa city.
