Synergisms of RN-222 reduction emanations with different thickness plaster from red brick
Radon (Rn-222) is noble gas formed by the decay of radium (Ra-226), which is one of the nuclides formed in the disintegration series from uranium (U-238). Radon has been considered the second leading cause of lung cancer and leading environmental cause of cancer mortality by the Environmental Protec...
