Decay
The process by which an unstable
Ú
Nuclide (parent) loses energy by emitting
Ú
Ionizing
Radiation and transforming to another nuclide (daughter). Decay of a single nuclide is spon-
taneous, that is, it neither needs external triggering nor is it predictable. The average decay
rate of a large number of nuclides, however, is predictable and usually given as
Ú
Half Life .
Also known as: Disintegration, Radioactive Decay

Dose
A measure of the
Ú
Ionizing Radiation energy transfer to, for example, tissue (
Ú
Sievert ).
Dose Rate
The quotient of

Dose given in

Sievert and time.

Electromagnetic Radiation
Self-propagating waves comprising electric and magnetic ield components. The
Ú
Spectrum
ranges from low-frequent radio waves (longer waves), microwaves, visible light, ultraviolet
radiation, X-rays up to high-frequent
Ú
Gamma Radiation (shorter waves).
Electron
A subatomic particle with a negative electric charge, counterpart of the
Ú
Positron . It is emit-
ted as
Ú
Beta Radiation .
Electron Volt (eV)
The electron volt is a non-
Ú
SI unit of energy (
Ú
Joule ) employed in radiation physics. It is
equal to the amount of kinetic energy gained by a single unbound electron when it accelerates
through an electrostatic potential difference of one volt.
1 eV ≈ 1.602177 × 10 J
