Synergism of Rn-222 reduction emanation with different type of coatings from red bricks

Radon is one of the radiation sources which occurs naturally in the environment. It is a form of radioactive gas and one of the contributors for lung cancer besides smoking due to the emission of alpha particles. Radon (Rn-222) can be found in common building materials such as the red bricks and it...
