Over 1 Million Bq/kg of Radioactive Cesium from the Mysterious Black Dust in Minami Soma City
Over 1 Million Bq/kg of Radioactive Cesium from the Mysterious Black Dust in Minami Soma City
Minami Soma City assemblyman Koichi Ooyama discloses the result of the test of the mysterious black dust found in locations in Minami Soma City, Fukushima Prefecture.
A blogger whom I featured before, "Night that never ends", has been measuring radiation on the strange, black dust he finds in many locations in Minami Soma City, mostly on the road surface. His geiger counter (Inspector) measures all alpha, beta, gamma radiations and x-ray, and his measurement on the surface of this black dust was 295 microsieverts/hour.
Assemblyman Ooyama apparently sent the sample to Professor Tomoya Yamauchi of Kobe University. Professor Yamauchi did the test, and here's the result, from Assemblyman Ooyama's blog:
Cs-134: 485,252 Bq/kg
Cs-137: 604,360 Bq/kg
TOTAL: 1,089,612 Bq/Kg
