Biological monitoring of these chemicals has several advantages over environmental monitoring because the former measures the internal dose rather than the exposed dose, and accounts for exposure from all sources (residential and work), all environmental pathways (through air, water, food, soil, surfaces), and all routes of absorption (ingestion, dermal, inhalation).
The exposed dose of the three is estimated to be well beyond that level, ranging from 3 to 17 Svs, according to the Science and Technology Agency's National Institute of Radiological Sciences in Chiba, east of Tokyo.
