How Does Radon Enter The Body?

It is generally believed that skin acts as a barrier to radon, so, the only way that radon can enter into a person's body is if it is inhaled (breathed in) or ingested (when water is consumed).

A person's lungs are particularly vulnerable to the effects of radon.

If ingested, radon goes to the gastrointestinal (GI) tract first, then to the liver and parts of the circulatory (blood) system. From the circulatory system radon enters the lungs and body tissues.
