3.11.1.1 General<br />

The nucleonic gauges (NGs), also known as Ionising radiation gauging devices<br />

(IRGDs), consist of source housing and radiation source such as radioactive<br />

material or electrically generated X-ray sources. The NGs are commercially<br />

manufactured and extensively used in all types of industries in our country.<br />

The gauges are used <strong>for</strong> measuring the various monitoring and quality<br />

controlled parameters during construction and manufacturing process. This<br />

includes online measurement of various physical parameters such as thickness,<br />

density, level, moisture content and analysis of the composition of metals.<br />

The typical activity of radiation sources used in NGs ranges from few MBq<br />

to hundreds of GBq.<br />

3.11.1.2 Site and Layout Plan Approval<br />

The manufacturing workplace should be in non-residential or industrial<br />

premises, and should have sufficient space <strong>for</strong> secured storage of the radiation<br />

sources. The applicant should submit application <strong>for</strong> the Authorisation to<br />

manufacture the IRGDs/NGs along with detailed layout plan indicating the<br />

source handling area and provisions made <strong>for</strong> secured storage of radiation<br />

sources and no separate layout plan approval is issued. The Applicant should<br />

also submit the authenticated documents issued by relevant Government<br />

agency showing the status of ownership/lease of the premises.<br />

3.11.1.3 Commissioning and Operation<br />

No separate clearance <strong>for</strong> commissioning and operation of the facility<br />

manufacturing nucleonic gauges is required. However, Authorisation <strong>for</strong><br />

commercial production of IRGDs/NGs is required as mentioned in subsection<br />

3.11.1.2 and the Application <strong>for</strong> the same is given in Annexure 35. The AERB<br />

may carry out the inspection of the manufacturing facility.<br />

Prior to seeking the permission <strong>for</strong> the Authorisation, the manufacturer should<br />

have:<br />

Personnel monitoring services<br />

Safe and secure source storage facility<br />

Facility to demonstrate the compliance with type approval<br />

per<strong>for</strong>mance tests<br />

Emergency preparedness plans and procedures (EPP)<br />

Based on the review of the application and inspection, if any, AERB may<br />

issue Authorisation <strong>for</strong> the commercial production of NGs/IRGDs.<br />
