Description/Abstract:
PROCEEDINGS OF THE THIRD NATIONAL SYMPOSIUM ON RADIOECOLOGY, 05/10 - 0 5/12/71, OAK RIDGE, TN. CYCLING OF 137-CS AND OTHER FALLOUT RADIONUCL IDES IN NATURAL LICHEN COMMUNITIES OF NORTHERN ALASKA WAS STUDIED BY P ERIODIC SAMPLING ON A YEAR-ROUND BASIS DURING THE PERIOD 1964-1970. M AXIMUM CONCENTRATIONS USUALLY OCCURRED DURING SUMMER MONTHS AND MINIMA DURING WINTER MONTHS. VERTICAL STRATA OF LICHENS, HUMUS, AND SOIL TA KEN AT THOSE TIMES SHOWED PRONOUNCED SEASONAL SHIFTING OF RADIONUCLIDE S BETWEEN COMMUNITY COMPONENTS. THESE DATA PARTIALLY ACCOUNT FOR THE SUDDEN INCREASE IN 137-CS BODY BURDENS OF NORTHERN ALASKA CARIBOU DUR ING SPRING MONTHS OF EACH YEAR AND HAVE IMPORTANT IMPLICATIONS IN THE ESKIMO POPULATIONS DEPENDENT UPON THE CARIBOU FOR BASIC FOOD SUPPLIES .
