But radon decay goods, radioactive reliable particles, A great deal smaller than home dust, float in the air and have trapped inside our lungs, trachea, and bronchi. At 4 pCi/L Every liter of air consists of 70,000 radon atoms. But fewer than 1% of the inhaled atoms get trapped and we So accumulate in our airways about 600,000 radioactive particles just about every hour. Once they shoot out alpha particles, they damage the DNA of epithelial cells, resulting in mutations and lung cancer.
Basically it is a canister, you put it in the basement, retain it two feet from the floor or the bottom. Open up it up, leave it there 48 hrs, ship it in.
