Hot spring medical circles at home and abroad believe that there are three major hot spring therapies in mineral spring therapy: radon hot spring, salt hot spring and hydrogen sulfide hot spring, among which radon hot spring therapy plays a very important role. A large number of facts have proved that radon hot springs are beneficial to people's health. Radon is a kind of weak radioactive gas produced by radium in the process of disintegration. Radon itself is an inert gas and does not combine with other elements. It is heavier than air, soluble in water, oil and fat, and more soluble in air.

Radon is closely related to human beings. Dr. Zhu Li, Ph.D. in Geochemistry, executive deputy director of the Radiation Protection Research Office of Tsinghua University, member of the leading group of radon monitoring and prevention research of the Ministry of Health, the State Environmental Protection Administration and the Ministry of Land and Resources, said in the book Radon and Indoor Environment co-edited by others that "radon has been used by some people for a long time to treat rheumatism and relieve pain". Of course, everything has two sides. If you are exposed to radon in a high concentration room for a long time, the relative risk of lung cancer will increase, which has formed a common sense in the world.

After long-term research, scientists believe that in hot spring water, the α, β and γ rays emitted by radon have biological effects on human body, and have the functions of medical treatment, health care and health preservation.
