are materials, which produce radiation, such as X-rays,
gamma rays, alpha particles and beta particles.
Depending on the level of exposure, radiation can
produce adverse health effects. It can adversely affect individuals who are
directly exposed as well as the children. Listed below are three radio nuclides, their source, the route of their entry into our
body, and the health effects that they produce after they enter our body. To

||Route of Exposure
|Underground uranium mining, sea water. X-ray
targets, nuclear explosion.
Effects - burns, loss of hair, nausea, loss of fertility.
Effects - shortness
of breath, cancer of the mouth region, pharynx, and larynx or
leukemia, physical deformities, and mental retardation in children of
|Basements of buildings and houses, sump
in foundations and concrete floors, ground water( deep well).
|Radium forms when isotopes of uranium or
thorium decay in the environment. It is in virtually all rocks, soil,
and water at low levels.
