@sergeygainullin5753 боюсь, что Вы не найдете нормальных научных исследований о пользе рандона. Зато держите о вреде радона от всемирной организации здравоохранения:
The adverse health effects of exposure to radon are caused primarily by damage due to
alpha-particles. The possible effects will depend on exposure level. The main danger
from high radon exposure is an increased risk of lung cancer. Radon as a noble gas is
rapidly exhaled after being breathed in; however, radon progeny, combine with other
molecules in the air and with particles of dust, aerosols or smoke, and readily deposit in
the airways of the lung. While lodged there, the progeny emit ionizing radiation in the
form of alpha particles, which can damage the cells lining the airways. Experiments have
confirmed that ionizing radiation affecting bronchial epithelial cells could cause cancer.

Epidemiological studies on thousands of uranium miners in different countries, including
Germany, USA, Canada, Czechoslovakia, and others, also support this fact. Analyses
have been undertaken of several miner studies, totalling 68,000 men of whom 2,700 died
from lung cancer. An increased risk of all histological types of lung cancer, including
small cell carcinoma, adenocarcinoma, and squamous cell carcinoma, has been associated
with occupational exposure to radon. But exposure to radon in houses can also lead to
lung cancer. It is believed, for example, that every year more than 15 000 deaths from
lung cancer occur due to radon exposure in the United Sates and more than 2 500 deaths
in the United Kingdom.
The risk of lung cancer from radon in home can be estimated by two ways: by direct
epidemiological studies of residential radon and by projecting occupational risk estimates
to lower levels of radon in homes. The uncertainties associated with residential studies
are larger than those with miner studies, primarily because the risk is smaller at the low
exposures encountered in most homes. It is also difficult to estimate the radon exposures
that people have received over their lifetimes, probably in several houses. Despite the
uncertainties , it is clear that far more lung cancers are caused by smoking than are
caused by radon.
It is believed that the relationship between radon and risk of lung cancer is linear. In
other words, doubling the exposure doubles the risk and halving the exposure halves the
risk. Doubling of the risk means much more for a smoker, who is already at high risk of
lung cancer, than for a non-smoker with a very small base line risk. Lung cancer risk
from residential radon exposure is substantially lower since the exposure in homes is
much lower than in mines, although the risk increases with radon concentration level and
duration of exposure. For life-time exposure to radon of 20 Bq/m3 level at home the risk
of lung cancer is estimated to be 0.3% (or 3 deaths in 1000 people). For comparison, risk
of accidental death at home is 0.7% (or 7 in 1000).
It has been suggested that other effects of radon exposure include increased risk of nonmalignant
respiratory diseases but this is much less clearly established than the lung
cancer risk. It is still not clear whether children are more sensitive to radon exposure.
Studies on childhood leukaemia (the most common form of cancer in childhood) have
not found clear evidence of risk associated with radon concentrations in homes.
И это они переживают из-за ненарочного взаимодействия с радоном. Представьте же, когда специально люди с ним взаимодействуют? https://www.ncbi.nlm.nih.gov/books/NBK143219/
