Vision for the IAEA Safety Standards

• Complete, consistent, coherent, integrated and user-friendly safety series with a manageable number of publications

• Global Reference used worldwide by Member States to deliver a harmonized high level of safety for protecting people and the environment from the harmful effects of ionizing radiation

• Sustainable continuous improvement system through effective feedback from application of SSs

Basic Safety Standards Review and Revision Process

IAEA

BSS Secretariat

Resolution GC(49)/RES/9A 2005 Review BSS

Resolution GC(50)/RES/(10) 2006 Revision BSScoordinated by a secretariat

Objectives:• To support and facilitate the revision by ensuring that the interests, views and responsibilities of each cosponsoring organisation are fully taken into account• To provide a forum for cosponsor organisations to inform each other of developments that may need to be taken into account• To coordinate the approval process of the cosponsoring organisations for the revised BSS

The IAEA secretariat has the overall responsibility for the revision of the BSS.The IAEA chairs meetings of cosponsoring organisations, which will generally be held in Vienna.

Guidance from RASSC and BSS Secretariat

Retain BSS role as the international benchmark for radiation safety standards across all fieldsRecognize the need for stability in international standards; so be conservative and justify proposed changesMaintain close connection with ICRPKeep cosponsors (WHO, PAHO, ILO, NEA, etc) and all Safety Committees fully involvedSeek and take note of feedback from Member States on current BSSAssist developing countries to participate.

Structure of revised BSS

• Section 1: Introduction• Section 2: General Requirements for Protection and Safety• Section 3: Planned Exposure Situations• Section 4: Emergency Exposure Situations• Section 5: Existing Exposure Situations• Schedules:

Schedule I: Exemption and ClearanceSchedule II: Categorization of Radioactive SourcesSchedule III: Dose Limits for Planned Exposure SituationsSchedule IV: Criteria for Use in Emergency Preparedness and Response

Interface between safety and security is being reviewed by NSNS to assure a link with the security guidance

Basic Safety Standards

IAEA

Current Status

• Review by RASSC/WASSC in June 2009 of version 2.0 and agreement to start transforming in the new format

• Continuous work by the secretariat together with cosponsors on the “new format” document – cosponsors meeting next week

• Review by RASSC/WASSC of the “overarching requirements” and associated conditions in Nov 2009 – draft to be sent to RASSC on 1 October 2009

• Submit to Member State for comment during Jan/Feb2010, in the new format, together with a document that tracks and justifies changes

• Continue to involve developing countries through regional workshops

• Outstanding issues: radon, safety-security interface

• Optimization• Section 2: General Requirements for Protection and

Safety• Each party with responsibilities for protection and safety is

required to ensure that protection and safety are optimized.

Basic Safety Standards – draft 2.0

IAEA

Basic Safety Standards – draft 2.0

• Optimization• Section 3: Planned Exposure Situations

• Generic Requirements• Registrants and licensees are required to ensure that protection and safety

is optimized, and that appropriate constraints are used.• Requirements in relation to human imaging for for purpose other than

medical diagnosis and treatment, require optimization subject to dose constraints

• Occupational Exposure• Employers, registrants and licensees are required to ensure that

occupational protection and safety are optimized.• Employers, registrants and licensees are required to involve workers in

optimization of protection and safety, and to use constraints as part of optimization process.

IAEA

Basic Safety Standards – draft 2.0

• Optimization• Section 3: Planned Exposure Situations

• Public exposure• The regulatory body to establish or approve dose constraints for

optimization of protection and safety, taking into account good practice and dose contribution from other practices.

• Registrants, licensees and suppliers to apply principle of optimization, taking into account good practice etc.,.

• Registrants and licensees to ensure that control of discharges is optimized.• Medical exposure• Registrants and licensees to ensure optimization process for medical

exposures• Diagnostic Reference Levels are a tool for optimization process• Dose constraints used in optimization of protection and safety of carers and

comforters• Dose constraints used in optimization of protection and safety of volunteers

in biomedical research

IAEA

Basic Safety Standards – draft 2.0

• Optimization• Section 4: Emergency Exposure Situations• Emergency management system to provide for justified and optimized

protection strategies, which will include reference levels set typically between 20 mSv and 100 mSv effective dose, expressed in terms of residual dose, and dose contributions from all exposure pathways. The protection strategy is to be optimized to reduce exposures below the reference level.

• In implementing the emergency response arrangements, the expected residual dose is compared with the applicable reference level, giving priority to those groups whose doses exceed the reference level.

IAEA

Basic Safety Standards – draft 2.0

• Optimization• Section 4: Existing Exposure Situations• The appropriate authority to establish a strategy for managing an existing

exposure situation shall ensure that it defines its objectives and appropriate reference levels.

• The reference levels are to be typically expressed as an annual effective dose to the representative person in the range 1–20 mSv or other equivalent quantity, the actual value depending on the feasibility of controlling the situation and past experience in managing similar situations.

• Remedial and protective actions to be optimized, with priority shall be given to those groups of individuals whose residual dose exceeds the reference level and all reasonable steps shall be taken to avoid doses remaining above the reference levels.
