RADIATION AND

RADIOACTIVITY

nucleus that contains protons and

neutrons. Neutrons do not have an

electrical charge while protons have a

positive charge. Electrons are

negatively charged particles that orbit

the nucleus and balance the positive

electrical charge of the protons. The

nucleus of the atom is held together by

a delicate balance among the nuclear

particles allowing the atom to remain

stable. Any change in this structure will

cause the nucleus to become unstable

or radioactive until stability is restored.

Ionizing Radiation

Ionizing radiation is the type most

commonly referred to when discussing

radioactivity. It is radiation with enough

energy to remove tightly bound

electrons from the atom creating ions.

The GM tube in the radiation meter is

capable of detecting ions emitted from

certain radioactive particles and waves.
