History 
A Radiation Cell was established in 1956 at the Defence Science Laboratory in Delhi, which is the origin of the institute, which can be traced back to this year. As part of the initial assignment, a study was to be conducted on the consequences of the use of nuclear weapons and other weapons of mass destruction as well. In 1959, the radiology cell was upgraded to the Radiation Medicine Division, and in 1961, the Institute of Nuclear Medicine and Allied Sciences was established.
