New Research Section Added - Radon Therapy

As an environmental agent that is toxic at high concentrations, radon can exert a beneficial effect on the immune system when it generates low radiation doses in man.

These documents also analyze the effects found in the study of human populations exposed to low radiation doses and those occurring in people living in areas with a high level of background radiation. Lastly, it deals with the effects on the immune system of patients treated in radioactive spas where radon is the main agent. The analysis of this set of data indicates that radon exerts an effect on the immune system.

There have been several stages in the history of radon therapy, including the times when it was only indirectly known by its positive health effects millennia ago; the first decades of scientific exploration of its properties and concentration in various sources of mineral waters after its discovery, and uses in old or newly established therapeutic facilities.
