137Cs in the population of northern Sweden

Whole-body content of 137Cs has been measured in both 1991 and 1992 in the population of northern Sweden, with a special interest taken in the Saami population.

Two groups of individuals were randomly chosen, one group representing the total population of the area, and the other the members of the Saami communities. In order to investigate whether 15 year old students could be regarded as a representative sample of the total population, measurements of whole-body content and urine samples were performed on school classes in two of the areas
