OUR EXPOSURE TO RADON IN A NUT SHELL...
These dust particles are frequently inhaled into the lungs or ingested (from drinking water) into the gastrointestinal tract.
The inhaled particles immediately attach to the lung alveoli while the ingested radon progeny are absorbed into the bloodstream and ultimately transported to the lungs.
The deposited progeny readily undergo subsequent radioactive decay processes by emitting alpha radiation which slowly penetrates the inner lung surface, disrupts DNA structure within lung cells, and can potentially induce lung cancer.
