This means that a person living in an average European dwelling with 50 Bq/m 3 has a lifetime excess lung cancer risk of 1.5–3 × 10 −3. Similarly, a person living in a dwelling with a high radon concentration of 1000 Bq/m 3 has a lifetime excess lung cancer risk of 3–6%, implying a doubling of background lung cancer risk. [63]
Radiation hormesis is the conjecture that a low level of ionizing radiation (i.e., near the level of Earth's natural background radiation) helps "immunize" cells against DNA damage from other causes (such as free radicals or larger doses of ionizing radiation), and decreases the risk of cancer. The theory proposes that such low levels activate ...
The public needs to be aware of radon risks and the means to reduce and prevent these." [2] In 1996 [citation needed], WHO published a report containing several conclusions and recommendations covering the scientific understanding of radon risk and the need for countries to take action in the areas of risk management and risk communication.

According to the European pooling study, there is a difference in risk for the histological subtypes of lung cancer and radon exposure. Small-cell lung carcinoma, which has a high correlation with smoking, has a higher risk after radon exposure. For other histological subtypes such as adenocarcinoma, the type that primarily affects non-smokers ...
The Iowa Radon Lung Cancer Study, which was overseen by Field, is widely considered the most comprehensive residential radon study ever performed. The study [ 3 ] found a 50% increased lung cancer risk at the EPA's radon action level of 4 pCi/L. Field is considered one of the leading advocates in the world for the reduction of radon exposure in ...
This is because the baseline cancer rate is already very high and the risk of developing cancer fluctuates 40% because of individual life style and environmental effects, [6] [7] obscuring the subtle effects of low-level radiation. An acute effective dose of 100 millisieverts may increase cancer risk by ~0.8%.
Colorectal cancer rates in people under 55 are increasing and it's more advanced. Experts are unsure why, but think diet, exercise and environment play a role.
