TOKYO (Reuters) - Radiation hot spots have been found at the J-Village sports facility in Fukushima where the Tokyo 2020 Olympic torch relay will begin, Greenpeace Japan said on Wednesday.
Greenpeace found that radiation levels around the recently refurbished venue, which also hosted the Argentina team during the Rugby World Cup earlier this year, were significantly higher than before the Fukushima Daiichi nuclear reactor meltdown following the March 2011 earthquake and tsunami.
Greenpeace's survey found radioactivity readings taken at J-Village on Oct. 26 as high as 71 microsieverts per hour at surface level.
People are exposed to natural radiation of 2,000-3,000 microsieverts a year, so anyone staying in the vicinity of J-Village for two or more days could be exposed to more than that.
