According to the official website of the World Health Organization, radon easily leaves the ground and enters the air, where it decays and releases radioactive particles. When people breathe, these particles are deposited on the cells of the respiratory wall, where they can destroy DNA and may lead to lung cancer. Radon is the second leading cause of lung cancer, second only to smoking.
According to WHO, for a long time, the risk of lung cancer increased by 65,438+000 Bekkerel per cubic meter for every one point increase in average radon concentration. The increase of lung cancer risk is directly proportional to the increase of radon exposure. In many countries, drinking water comes from underground water sources, such as spring water, well water and drilling water. The radon concentration of these water sources is usually higher than the surface water of reservoirs, rivers or lakes, and radon dissolved in drinking water can be released into indoor air.
