Post-Chernobyl 134Cs and 137Cs Levels at Some Localities in Northern Canada
Samples of lichen, moss and caribou meat from the high and central arctic regions of Canada were measured for 137Cs due to the Chernobyl accident of April 1986. They were compared to lichen samples from the boreal area of Wood Buffalo National Park, Alberta, and to moss samples from the temperate Ni...
