Synergisms of RN-222 reduction emanations with different thickness plaster from interlocking block
Radon is radioactive materials which exist in human surrounding and it dangerous to human and environment because it is tasteless, invisible, touchable colourless and odourless. It is a decay product of Ra-226 and ultimately of U-238, both of which are naturally contain in soil and rocks which produ...

Radon is radioactive materials which exist in human surrounding and it dangerous to human and environment because it is tasteless, invisible, touchable colourless and odourless. It is a decay product of Ra-226 and ultimately of U-238, both of which are naturally contain in soil and rocks which produce from the Earth’s crust. Rn-222 originated from rock and soil which can enter any building through cracks, construction joint and also from materials that build it.
