Radiation Hazard
Radiation Hazard

• Radiation hazards may be divided according to:

 External radiation exposure

o Hazard is related to high penetrating radiation source outside the
body.

o Such radiation (e.g. electromagnetic radiation, high-energy beta

and neutron) could penetrate the skin and body to cause harm to
the body.

 Internal radiation exposure

o Hazard is related to radiation source in the body.

o It involves radiation with low penetrating power but usually with
high LET that can cause significant internal damage (e.g. alpha and

beta particles).
