Regional Workshop on the BSS, Kuala Lumpur, Malaysia, 2012

The IAEA organized a regional workshop on the IAEA General Safety Requirements: GSR Part 3: Radiation Protection and Safety of Radiation Sources: International Basic Safety Standards (the BSS). The workshop was hosted by the Malaysian Atomic Energy Licensing Board (AELB) and was held in Kuala Lumpur, Malaysia, from 17 to 20 April 2012.

Following its approval by the IAEA’s Board of Governors in September 2011, GSR Part 3 was published in November 2011 and replaces the previous edition of the BSS published in 1996.

The purpose of this workshop was to discuss the changes to the 1996 edition of the BSS that have been incorporated into the 2011 edition of the BSS (GSR Part 3) to consider how the BSS will be implemented in Member States, and to identify areas where further guidance is required.

The workshop was attended by 21 participants from 10 countries: India, Indonesia, Iran, Iraq, Malaysia, Philippines, Qatar, Thailand, United Arab Emirates and Vietnam.

Workshop programme

The workshop started with an overview of the IAEA Safety Standards and an overview of the major changes made to the BSS in the revision process i.e. the major changes from SS115 to GSR Part 3. These were followed by 12 sessions on topical areas where there have been significant changes: dose limits and dose constraints; implications of the new dose limit for the lens of the eye; responsibilities and justification in medical exposures; optimization in medical exposures; unintended and accidental medical exposures; human imaging for non-medical purposes; exemption and clearance; regulatory control of consumer products; regulatory control of NORM; emergency preparedness and response; reference levels in existing exposure situations; and radon in existing exposure situations.

The concluding session discussed the key issues from the workshop for the Agency to address during the development of new Safety Guides or the revision of existing Safety Guides.

There were three presentations in each session: one presentation by an IAEA expert to focus on issues relating to the topical area considered during the revision process, and two presentations by Member States on issues that the Member State faced in implementing the BSS in that topical area. Suggestions of where the IAEA needed to develop further guidance were also presented. Each presentation was a catalyst for ensuring discussion and feedback.


A report summarizing the feedback from the workshop has been prepared. The Agency received feedback from the participants to develop guidance material on the following topics:

  • The setting of numerical values for, and the use of, dose constraints
  • The implementation for workers of the new dose limit for the lens of the eye
  • How to establish values for diagnostic reference levels for medical exposures
  • Radiation protection of carers and comforters, and for volunteers in biomedical research
  • The justification of procedures for non-medical imaging of humans for purposes other than medical diagnosis, medical treatment or biomedical research
  • Development of clearance values for radionuclides additional to those included in Table I-2 of Schedule I of the BSS, e.g. Ca-41 and Ba-133
  • The development of a comprehensive list of consumer products to facilitate the application of standards
  • The criteria for transition from an emergency exposure situation to an existing exposure situation
  • The implementation of reference levels for and regulatory control of doses to aircrew
  • The establishment of a reference level for radon in dwellings for the purposes of management
