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 ”.
