Polonium is efficiently absorbed by living organisms and is estimated to contribute approximately 7% of the total effective dose from ingested natural internal radiation. The primary source of atmospheric ²¹⁰Po is the decay of radon-222 (²²²Rn), which precipitates onto land and water surfaces, including crops. In Cannabis sativa, ²¹⁰Po accumulates primarily through direct deposition on leaf surfaces and from fertilizers, particularly phosphate fertilizers.
