Radon can enter homes through cracks in floors, walls, or foundations, and collect indoors. It can also be released from building materials, or from water obtained from wells that contain radon. Radon levels can be higher in homes that are well insulated, tightly sealed, and/or built on soil rich in the elements uranium, thorium, and radium.

Radon and progeny interact indoors with aerosol particles via complex physical phenomena. These produce an inhalable radioactive mixture Water samples collected from different sources were analysed for radon concentrations in order to evaluate the health effect associated with radon in water. The radon concentrations were in the range of 3.56-98.57, 0.88-25.49, 0.73-1.35 and 0.24-1.03 Bq.L-1 for borehole, well, packaged and utility water, respectively. The Radon-222 gas penetrates through soil and rocks and dissolves in water (Xinwei, 2006).

Radon 222 The primary sources of indoor radon-222 are radon-222 gas emanations from soil and rock, off-gassing of waterborne radon-222 into indoor air, and emanation of radon-222 from building materials. However, in most cases, the major source of indoor radon-222 is from ground sources (e.g., soil) underlying the structure.
