Radiation hazards
Rad
Environment; Radiation hazards
The special unit of absorbed dose. One rad is equivalent to 100 ergs/gram or 0. 01 J/kg.
Bioassay
Environment; Radiation hazards
The determination of kinds, quantities, or concentrations, and, in some cases, the locations of radioactive material in the human body, whether by direct counting (in vivo) or by analysis and ...
As low as reasonably achievable (ALARA)
Environment; Radiation hazards
Making every reasonable effort to maintain exposures to ionising radiation as far below the dose limits as practical, consistent with the purpose for which the licenced activity is undertaken. It ...
Beta particle
Environment; Radiation hazards
High speed electrons, which are emitted from the nuclei of radioactive atoms during radioactive decay, as a result of the transformation of a neutron into a proton. They can be stopped by a thin ...
Annual limit on intake (ALI)
Environment; Radiation hazards
Annual intake of a given radionuclide by "Reference Man" which would result in either a committed effective dose equivalent of 5 rems or a committed dose equivalent of 50 rems to an organ or tissue.
Alpha particle
Environment; Radiation hazards
A positively charged particle ejected spontaneously from the nuclei of some radioactive elements. It is identical to a helium nucleus, with a mass number of 4 and a charge of +2.
Background radiation
Environment; Radiation hazards
Radiation from cosmic sources; naturally occurring radioactive materials, including radon and fallout from nuclear weapons tests.
