- Small amount of cesium detected in Fukushima children’s urine (Kyodo News, July 1, 2012):
A small amount of radioactive cesium was found in the urine samples from 141 infants and young children living in Fukushima Prefecture, where the crippled nuclear power plant is located, among 2,022 of those surveyed, a Japanese research group said Saturday.
Three urine samples contained more than 10 becquerels of cesium per kilogram, including a case with 17.5 becquerels. Ten becquerels or less of cesium was found in the samples of the other 138, the Yokohama-based Isotope Research Institute said.
The urine samples also contained about an average 64 becquerels of radioactive potassium.
