Cesium-137 body burdens in Norwegian Lapps, 1965-1983

Journal Article · · Health Phys.; (United States)
; ;

Results of measurements of the whole-body contents of /sup 137/Cs during the period 1965-1983 in Lapps from the Kautokeino area in Norway are reported with measurements of /sup 137/Cs in reindeer meat during the period 1966-1983. By using available data on /sup 137/Cs in precipitation for the period 1950-1980, transfer coefficients from /sup 137/Cs in precipitation to reindeer meat have been assessed. A correlation between the /sup 137/Cs content in reindeer meat and the /sup 137/Cs content in Lapp reindeer breeders has been established. The average whole-body committed dose equivalent, H50, to the reindeer breeders from internally deposited /sup 137/Cs from intakes up to year 2000 was assessed to 13 mSv with a peak value of 30 mSv. In comparison, the corresponding committed dose equivalent to the Norwegian population from internally deposited /sup 137/Cs has been estimated to be about 1 mSv. The higher intake of /sup 137/Cs by reindeer breeders is due to the lichen-reindeer-man exposure pathway.
