Volume 2 - Atomic Energy Regulatory Board

Betatron
An electron accelerator in which electrons are accelerated in an increasing magnetic
field maintaining a stable orbit of electrons.
Commissioning
The process during which structures, systems and components of a nuclear and radiation
facility, on being constructed, are made functional and verified to be in accordance
with design specifications and to have met the performance criteria.
Competent Authority
Any official or authority appointed, approved or recognised by the Government of
India for the purpose of the Rules promulgated under the Atomic Energy Act, 1962.
Computed Tomography
Reconstructive tomography in which image recording and processing are effected by
a computing system.
Consent
It is a written permission issued to the ‘consentee’ by the regulatory body to perform
specified activities related to nuclear and radiation facilities. The types of consents
are ‘licence’, ‘authorisation’, ‘registration’, and ‘approval’ and will apply according
to the category of the facility, the particular activity and radiation source involved.
Consentee
A person to whom consent is granted by the competent authority under the relevant
Rules.
Construction
The process of manufacturing, testing and assembling the components of a nuclear or
radiation facility, the erection of civil works and structures, the installation of
components and equipment and the performance of associated tests.
Contamination
Presence of a radioactive substances in or on a material or in the human body or other
place in excess of quantities specified by the competent authority.
Cyclotron
A device in which charged particles (other than electrons) travel in a succession of
semicircular orbits of increasing radii under the influence of a constant magnetic field
and are accelerated by traversing a number of times in an electric field produced by a
high frequency generator.
Decommissioning
The process by which a nuclear or radiation facility is finally taken out of operation, in
