Tokyo officials are to start decontamination of a 92-hectare park where high levels of radiation have been detected.
On Monday, officials tested 14 locations at Mizumoto Park in Katsushika Ward, following reports from the public about radiation hot spots there.
Thirteen of tested locations registered radiation above one microsievert per hour at one meter above ground, with the highest reading at 1.22
Since last year’s accident at the Fukushima Daiichi nuclear plant, the ministry has received about 150 reports of Tokyo hot spots, as of March.
About Monday’s test:
- Mizumoto Park in Katsushika Ward
- Officials tested 14 locations
- Decontamination to start soon
- Reports from public led to decontamination
Note that 13 spots measured radiation levels between 1.00 and 1.22 microSv/hr, yet only 9 of the 13 ‘hotspots’ will be decontaminated, reports NHK:
“According to science ministry guidelines, decontamination is required
when radiation is at least one microsievert higher than surrounding
areas. Based on these guidelines, 9 of the 14 surveyed places in
Mizumoto Park will be decontaminated.”
