INTERNAL DOSE ASSESSMENT OF NATURAL URANIUM FROM DRINKING WATER BASED ON BIOKINETIC MODELING AND INDIVIDUAL BIOASSAY MONITORING: A STUDY OF A FINNISH FAMILY.

The article focuses on the nationwide survey on natural radionuclides in drinking water that displayed high concentrations of natural uranium in Finland. The concentrations of natural uranium in drinking water of the drilled wells were found out by radiochemical and alpha spectrometric methods in order to assess the radiation dose from the natural uranium to individuals. Uranium contents were assessed in the urinary samples of five members of a Finnish family through the substance of inductively coupled plasma-mass spectrometry. Similarly, theoretical biokinetic modeling of natural uranium integrated for the same persons was executed with the help of follow-up interviews.
