Consenting Process for Radiation Facilities - Atomic Energy ...

Well logging is an evaluation technique, which provides fast and detailed
data for subsurface and structural mapping of geological formation for
exploration of mineral resources particularly oil, gas and coal. The well
logging operation involves the use of sealed radioactive sources and portable
mini-neutron generators in suitable logging tool for oil exploration. The
different techniques like Neutron-Neutron (n-n) Logging, Neutron-gamma
(n- γ) logging, Gamma-Gamma (γ- γ) logging are used for detection purpose.
The commonly used gamma and neutron sources for this purpose are 137 Cs,
60
Co, 241 Am, 241 Am-Be and 239 Pu-Be.
3.12.2 Procurement of Source(s)
The well logging operation involves the use of sealed radioactive sources in
suitable logging tool for oil exploration. For this purpose, the applicant needs
to submit an Application to obtain consent for procurement of sealed
radioactive sources. This also requires submission of layout details for
radiation source storage facility, which is to be approved by AERB.
Based on review of the Application, AERB may issue Consent for the
procurement of sealed radioactive sources which includes approval of the
layout plan proposed for source storage facility.
In case of import of sealed radioactive sources, a ‘No Objection Certificate
(NOC)’/Consent for import as part of procurement need to be obtained from
AERB.
The Application form for obtaining Authorisation for NOC/Consent for
import/procurement of sealed sources for well logging operations is given in
Annexure 37.
3.12.3 Commissioning/Operation
On the procurement of radioactive source(s) by the applicant and its secured
storage in approved storage pit, the applicant should intimate the AERB about
the receipt of the source(s) and submit the Application for obtaining
Authorisation for Commissioning/Operation for well logging activities. The
AERB may conduct inspection at the site(s) where well logging operation(s)
are undertaken and source storage facilities located as and when required.
Prior to seeking Authorisation for use the radiation source(s) for well logging
operation, the applicant should have the following:
(i)
(ii)
(iii)
(iv)
Radiological safety officer (RSO)
Protection level dosimeters
Personnel monitoring services
safe and secure source storage facility
