Minimising exposure to radiation
Gamma rays from the earth and some
radioactive gases vary with the local
geology. It makes sense to avoid very
radioactive building materials and
prevent radioactive gas entering homes.
Cosmic radiation is slightly higher
near the earth's poles and at high
altitude.
It is sensible to avoid food or
drink known to have higher than average
levels of radioactivity.
Medical use of radiation must be
restricted to occasions where benefit
to health outweighs the risks involved.
