irradiation facilities are in use for preservation of food products,
sterilization of health care products, polymerisation of wood, vulcanisation
of rubber and such purposes for which high intensity irradiation
is required. The high intensity gamma radiation processing facility
considered here is of land-based stationary installation type. Land-based
gamma radiation processing facilities are either dry source storage
or wet source storage using several GBq of suitably encapsulated
radioactive material (60Co or 137Cs) for radiation processing of
the target material.
AERB carries out multi-tier review at all the stages of consenting
process involved for installation and operation of GRPF. The various
stages involved and related regulatory procedures in brief during
installation and operation of GRPF are as follows;
Assessment and Approval
first stage of Consenting process is assessing the suitability of
the site in accordance with the AERB Safety Standard on Land-based
Stationary Gamma Irradiators [AERB/RF-IRRAD/SS-6
(Rev.1), 2008]. For this purpose the applicant has to submit
an application (Form ID: AERB/RSD/GRAPF/SA)
along with detailed site characteristics/ assessment report as per
APPENDIX 1. The applicant should also submit the authenticated documents
issued by relevant Government agency showing the status of ownership/lease
of the premises.
and Construction Approval
design of land-based gamma radiation processing facility should
meet the requirements specified by AERB in the Safety Standard on
Land-based Stationary Gamma Irradiators [AERB/RF-IRRAD/SS-6,
The general requirements for a GRAPF should cover: Layout of the
facility; Integral source units (ISU); Source-frame and Source-drive
mechanism; Water-pool and DM Plant; Ventilation system; Biological
shielding; Access control; Safety systems; Emergency systems; Product-movement
system and operating controls; and Material handling facilities.
preliminary safety analysis report (PSAR), as per APPENDIX
2, covering the above aspects along with the application for
obtaining Consent for construction/layout approval (Form ID. AERB/RSD/GRAPF/L&CA),
shall be submitted to AERB for review. PSAR should also contain
information regarding provisions/commitment of applicant for safe
disposal of spent/ disused sources. The facility should maintain
and keep available the reports on Quality Assurance (QA) during
construction of the facility as given in APPENDIX 3.
all the systems are in place, performance of each system should
be verified independently and also in an integrated manner. Acceptance
Test Reports (ATR) containing the results of the tests and Radiation
Protection Manual (RPM) should be prepared and submitted to the
AERB as per APPENDIX
4 and APPENDIX
5 respectively. The applicant has to also submit the application
for obtaining the authorisation for procurement of Co-60 source
The safety personnel such as Radiological Safety Officer (RSO);
Certified operators and Trained servicing and maintenance personnel
shall be available prior to the initial source loading. The application
form for obtaining approval to act as Radiological Safety Officer
is given in Form ID: AERB/RSD/RSO/APP.
applicant should submit the Final Safety Analysis Report (FSAR)
along with Quality Assurance Manual (QAM) of the design and systems
installed in the facility, to the AERB for review. These should
be in the formats given in APPENDIX
6 AND APPENDIX 3. Based on the review of information provided
in the ATR, FSAR, and obtained from inspections by the AERB, and
the trouble free performance of facility and radiation levels and
dosimetry results within the acceptable limits, the regulatory consent
in the form of Licence is issued by AERB. The application format
for obtaining the Licence for Commissioning and Operation is given
in Form ID: AERB/RSD/GRAPF/LCO.
the irradiation facility is used for radiation processing of food
products, additional review of dosimetry will be carried out to
ensure that the food items receive radiation dose as stipulated
in the Atomic Energy (Control of Irradiation of Food) Rules, 1996.
The application format for obtaining the Certificate of Approval
is given in Form ID:AERB/CA-FORM-III.
The appointment of a quality control officer (QCO) is mandatory
to look after the microbiological quality of food is mandatory.
The AERB grants Certificate of Approval in accordance with these
Rules. Based on the Certificate of Approval and the application
for Licence, the Licence for food irradiation is issued by the Department
of Atomic Energy, Government of India.
each stage of replenishment/ addition to the source strength of
the radiation facility, the Licensee is required to obtain authorisation
for procurement of additional Co-60 source (Form ID.:AERB/RSD/GRAPP/Co-60RPL).
After each source loading Licensee shall obtain a Consent for resumption
of routine operation.
Licensee is required to submit to the AERB, periodic status reports
(Form ID: AERB/RSD/QSSR/GRPF).
Unusual occurrences should be promptly reported within 24 hours
and this should be followed by a detailed report within the prescribed
period. The Licensee should operate the facility as per the requirements
stipulated in the AERB Safety Code on Operation and Maintenance
of Land-Based Gamma Irradiators, AERB/SC/IRRAD,1993.
the radiation processing facility is no longer to be used, the facility
should be decommissioned by returning the the radioactive sources
to the original supplier after obtaining prior approval from AERB.
The application format for obtaining the said Authorisation for
safe disposal of radioactive waste is given in Form ID: AERB/RSD/TR/TRF.
The Consentee is required to submit a report to the AERB on completion
of decommissioning, safe disposal of sources and personnel doses
received during decommissioning operations.
