Radioactive Isotopes Measured at Olympic and Paralympic Venues in Fukushima Prefecture and Tokyo, Japan

November 12, 2020

“This newly reviewed study of Radioactive Dusts and Dirt at Japanese Olympic sites and throughout Northern Japan by Fairewinds and Marco Kaltofen has four significant conclusions:

Different types of alpha and beta radioactive micro-particles were released at other times and landed in various locations throughout Japan. “The exclusive use of cesium-137 beta activity levels as a proxy for total internal and external exposure, therefore, introduces dose assessment errors.”

“Rooftops previously decontaminated in Minamisoma are recontaminated by airborne atmospheric dust containing radionuclides … from the Fukushima meltdowns. The data show a need for continuing reassessment and potentially, additional remedial work on many sites in Fukushima Prefecture.”

The greater Tokyo Olympic venues had activities similar to sample sites in the US. In contrast, Olympic sites in Northern Japan near Fukushima contained an average of about twice as much radioactivity as Tokyo, with Plutonium identified at the J-Village National Training Center.

Non-Olympic sites throughout Japan averaged 7.0 times greater beta activity than the Tokyo Olympic venues. These data show that remediation emphasized the Olympic venues over cleaning other contaminated parts of Japan.”
