Radiation hazards
Roentgen (R)
Environment; Radiation hazards
A unit of exposure to ionising radiation. It is that amount of gamma or x-rays required to produce ions carrying 1 electrostatic unit of electrical charge in 1 cubic centimetre of dry air under ...
Restricted area
Environment; Radiation hazards
An area, access to which is limited by the licensee for the purpose of protecting individuals against undue risks from exposure to radiation or radioactive materials. Restricted area does not ...
Sealed source
Environment; Radiation hazards
Radioactive material that is permanently bonded or fixed in a capsule or matrix designed to prevent release and dispersal under the most severe conditions which are likely to be encountered in normal ...
Secondary radiation
Environment; Radiation hazards
Radiation originating as the result of absorption of other radiation in matter. It may be either electromagnetic (e.g. Bremstrahlung from 32P betas passing through lead) or particulate in nature.
Scintillation detector
Environment; Radiation hazards
A radiation detection instrument comprised of a phosphor, photomultiplier tube(s), and associated electronic circuits for counting light emissions produced in the phosphor by ionising radiation.
Shallow dose equivalent
Environment; Radiation hazards
Applies to the external exposure of the skin or an extremity. This is the dose equivalent at a tissue depth 0. 007 cm averaged over an area of 1 square centimeter.
Rem
Environment; Radiation hazards
The special unit for dose equivalent. The dose equivalent in rem is equal to the absorbed dose in rads, multiplied by the quality factor.
