Industrial Gamma Radiography Exposure Device (IGRED)
An assembly of components necessary to make radiographic exposures and which
includes the source housing, mechanism for securing the source assembly, exposure
mechanism, that includes source drive associated system, positioning devices and guide
tubes.
Industrial radiography
Non-destructive testing of materials employing ionising radiation.
Ionisation
Formation of ions by the division of molecules or by the addition or removal of electrons
from atoms or molecules.
Irradiation
Exposure to ionising radiation.
Irradiators
A facility that houses a particle accelerator, X-ray machine, or large radioactive sources
for imparting high radiation doses to materials.
Licence
A type of regulatory consent, granted by the regulatory body for all sources, practices
and uses for nuclear facilities involving the nuclear fuel cycle and also certain categories
of radiation facilities. It also means authority given by the regulatory body to a person
to operate the above said facilities.
Limit
The value of a parameter or attribute (which is variable) used in certain specific activities
or circumstances that must not be exceeded.
Luminescence
Phenomenon in which certain substances, when excited, emit light of wavelength
characteristic of the substance.
Microtron
A cyclic accelerator in which electrons are guided by a constant magnetic field in
circular orbits of increasing radii, tangential to each other and accelerated at the
beginning of each orbit, by traversing an electric field produced by a radio frequency
generator.
