Low Level Check Sources

Low Level Check Sources:

Low level check sources are used for checking the efficiency of radiation monitors and instruments. It is also used for energy calibration experiments/studies  and as a tracer in well logging.

Note*- Source supplied under this category are not absolutely calibrated sources and hence no calibration certificate will be issued.

Procedure to procure low-level check sources from BRIT:

The application is to be submitted (separate application for each product code and quantity) in duly filled in the A-3 form (available in our web site http://www.britatom.gov.in/) along with specific source procurement authorization (NOC) obtained from AERB, through the e-Licensing of Radiation Applications (eLORA) System.

Points to be noted while applying for AERB NOC from eLORA System

  • Login to the Sealed source profile.
  • Under regulatory -> form sealed source -> Application for procurement.
  • Select the product as per the product models are given in the following list by confirming the make as BRIT and supplier as BRIT.
  • While filling the application the purpose of the use is to be mentioned as “check source ”.
