DEFINITIONS
Atomic Energy Regulatory Board (AERB)
A national authority designated by the Government of India having the legal authority
for issuing regulatory consent for various activities related to the nuclear and radiation
facility and to perform safety and regulatory functions, including their enforcement
for the protection of site personnel, the public and the environment against undue
radiation hazards.
Design Basis Threat (DBT)
The attributes and characteristics of potential insider and/or external adversaries, who
might attempt unauthorised removal of nuclear material or sabotage, against which a
physical protection system is designed and evaluated.
Radiation Facility
Any installation/equipment or a practice involving use of radiation-generating units
or use of radioisotopes in the field of research, industry, medicine and agriculture.
Radiation Surveillance
Measures that may be specified by the competent authority to provide adequate
protection either generally or in any individual case.
Radioactive Material/Radioactive Substance
Any substance or material, which spontaneously emits radiation in excess of the levels
prescribed by notification by the Central Government.
Sealed Source
Radioactive source material that is (a) permanently sealed in a capsule, or (b) closely
bounded and in a solid form. The capsule or material of a sealed source shall be strong

source was designed, as also under foreseeable mishaps.
Source
Anything that may cause radiation exposure, either by emitting ionising radiation or
releasing radioactive substances or materials.
