Scientists from the Institute of Industrial Ecology of the Ural Branch of the Russian Academy of Sciences measured the concentration of radioactive radon in energy-efficient houses and houses built during the Soviet era. The results showed that this figure is 1.2–2.4 times higher for new buildings. “News”.
The detected radon level is 2-4 times lower than the limit values determined by sanitary standards. The reason for the increase in radon concentration in energy-efficient houses is the thermal insulation of buildings, which prevents internal sealing and air circulation. At the same time, ventilating, insulating the floor and walls can successfully prevent gas stagnation in the apartment.
The gas is found in sand and soil, and from there it often enters settlements. Radon is colorless, odorless, and tasteless, and its offspring products – radioactive isotopes of polonium, bismuth and lead – settle in the lungs and can cause lung cancer.
It was previously reported that he had lung cancer due to radon. is is occupational disease of miners, asbestos workers.
