Troubled waters: Nuclear radiation found in B.C. may pose health concerns

A radioactive metal from the Fukushima nuclear plant disaster in Japan has been discovered in the Fraser Valley, causing researchers to raise the alarm about the long-term impact of radiation on B.C.’s west coast.
Examination of a soil sample from Kilby Provincial Park, near Agassiz, has for the first time in this province found Cesium 134, further evidence of Fukushima radioactivity being transported to Canada by air and water.
“That was a surprise,” said Juan Jose Alava, an adjunct professor in the school of resource and environmental management at Simon Fraser University, in an interview on Tuesday. “It means there are still emissions ... and trans-Pacific air pollution. It’s a concern to us. This is an international issue.”
Cesium 134 has a half-life of two years, meaning its radioactivity is reduced by half during that time. Its presence in the environment is an indication of continuing contamination from Fukushima.
A more persistent danger to people and marine life is radioactive Cesium 137, which has a half-life of 30 years, and bioaccumulates in the food chain.
