Consenting Process for Radiation Facilities - Atomic Energy ...

The Consentee shall arrange to constitute a Local Safety Committee with the
Head of the institution as Chairman and the RSO as Member Secretary to
review the safety status of all the radiation facilities in the institution. The
Committee may also include the service engineer as a member. The minutes
of the meetings and the action taken reports shall be available for inspection
by AERB.
3.5.2.6 Decommissioning/Disposal
Consent from the AERB should be obtained for decommissioning when the
accelerator is no longer to be used. The Consentee should arrange to check
for any contamination/induced activity in the treatment head and remove
depleted uranium, if any, for safe disposal. If no radioactive contamination is
present in the treatment head and nearby accessible areas, it can be
decommissioned which may include dismantling. If activity exists, the active
components should be disposed off separately. For the above, the Consentee
should obtain an Authorisation from AERB for transfer/disposal of radioactive
waste to the authorised waste management agency. The application format
for obtaining the said Authorisation for safe disposal of radioactive waste is
given in Annexure 50. The consentee is required to submit a report to AERB
on completion of decommissioning, safe disposal of sources and personnel
doses received during decommissioning operations.
3.5.2.7 Lead Time for Submission/Availability of Documents
The lead time for submission of documents at any stage of consenting process
is 60 days before the desired date of consent provided the application is
complete in all respects for review by AERB.
3.6 Computed Tomography (CT)/Interventional Radiology (CATH LAB)
3.6.1 General
Diagnostic facilities such as computed tomography and interventional
radiology are important requisites in hospitals now-a-days. Operation of
these facilities may pose radiation hazard to the operators and even the
patients, unless safety measures are regulated at the design, manufacture,
installation and operation stages of these facilities. AERB’s Consenting
process ensures safety at all these stages.
Computed tomography (CT) units are basically diagnostic X-ray units. The
dose received by patients in a typical CT imaging is many orders higher than
that of conventional radiography. In interventional radiology (Cath Lab) also,
as the procedure time is long and staff needs to be present in the near vicinity
of patient the dose to the patient, doctor and staff is high.
