title: Tritium in the urine in Finnish people.
abstract: Tritium in urine was analysed from 227 randomly selected Finnish adults. The people were 18 to 65 of age. Urine samples were collected over night. The mean activity concentration of tritiated water in urine was 2.5 Bq l(-1) and the maximum activity concentration 18.3 Bq l(-1). The minimum detectable activity varied from 1.5 to 2.3 Bq l(-1). Because organically bound tritium is approximately 10% of the total tritium, its concentration was below the detection limit and could be ignored. The mean effective dose for Finnish people from tritium was 2.4 x 10(-3) microSv y(-1).
