  1. Revision of the International Basic Safety Standards - BSS 115- Status Report - 2008 ISOE International ALARA Symposium Tsuruga, Japan, 13 – 14 November Renate Czarwinski & Pascal Deboodt Radiation Safety and Monitoring Section Division for Radiation, Transport and Waste Safety Department of Nuclear Safety and Security

  2. Revision of BSS SS115 International Basic Safety Standards for Protection against Ionizing Radiation and for the Safety of Radiation Source Status of revision: draft 1.0 International Cooperation with WHO, PAHO, FAO, ILO, OECD/NEA, EC, UNEP, ICRP, IRPA

  3. BSS revision process • Initial topical drafting meetings that were completed in May 2007 • Collation of the drafting group material by the IAEA Secretariat • The recommendations of a Technical Meeting (TM) held in Vienna from 16-20 July 2007 • Additional advice from a meeting of Cosponsoring Organizations from 3-4 September 2007

  4. BSS revision process (2) • Recommendations from RASSC/WASSC in their meeting in October 2007 • Drafting meeting with cosponsoring organizations and invited experts from 26 – 30 November 2007 • Drafting meeting with cosponsoring organizations and invited experts from 10 – 14 March 2008 • Drafting meeting with cosponsoring organizations and invited experts from 7 – 11 April 2008 • Review/drafting meeting with cosponsoring organizations 13 -16 May 2008 • Draft 1.0 made available by end June 2008

  5. Revision BSS - Draft 1.0 1. Introduction • Background • Objective • Scope • Structure Includes explanatory text on system of protection and safety, types of exposure situation, dose constraints and reference levels, protection of the environment, quantities and units

  6. Revision BSS - Draft 1.0 2. General Requirements for Protection and Safety • Responsibilities of government • Responsibilities of regulatory body • Principal parties • Management requirements • Implementation of radiation protection principles Contains requirements that apply to all types of exposure situations

  7. Revision BSS - Draft 1.0 3. Planned Exposure Situations • Scope • Generic requirements • Occupational exposure • Public exposure • Medical exposure Generic requirements include administrative requirements for notification and authorization, exemption and clearance, application of the system of protection and safety including justification, optimization, and dose limitation, and justification and regulatory control of non-medical imaging.

  8. Revision BSS - Draft 1.0 4. Emergency Exposure Situations • Scope • Generic Requirements • Public exposure • Exposure of emergency workers, • Transition from an emergency exposure situation to existing exposure situation

  9. Tailings Landslip River Landslip Landslip Revision BSS - Draft 1.0 5. Existing Exposure Situations • Scope • Generic Requirements • Public exposure • Occupational exposure Specific requirements for remediation of contaminated areas (supersede WS-R-3), radon in homes and workplaces, and radionuclides in commodities

  10. Revision BSS - Draft 1.0 Schedules • Schedule I: Exemption and Clearance • Schedule II: Dose limits for planned exposure situations • Schedule III: Criteria for use in emergency preparedness and response • Schedule IV: Categorization of radioactive sources

  11. Issues requiring further work Revision BSS - Draft 1.0 • Section 1 Background: explanation of the system of protection and safety: • Level of detail on dose constraints / reference levels to be included in section 1. Balance with other parts of the section 1 and guidance on selecting dose constraints / reference levels will be provided in Safety Guides supporting the BSS • Radon in planned exposure situations / existing exposure situations • Issue about maximum value for the reference level for workplace and for dwellings • On-going work by ICRP

  12. Issues requiring further work Revision BSS - Draft 1.0 • Exemption and clearance levels • Current BSS exemption levels apply for up to 1 ton of material, and are also used as exemption levels for transport of radioactive material. • RS-G-1.7 levels apply to bulk quantities of material. • Issue about whether the levels in the current BSS are still required. • Glossary • BSS within the Long Term Structure of Safety Requirements

  13. BSS revision: milestones • End June 2008 : Draft 1.0 completed complete ‘clean’ draft, together with tracking and justification of changes from SS115 • October / November 2008 – All Committees to conduct full first review of Draft 1.0 : ongoing • Workshop on Revision of BSS in Qatar 20 – 22ndJanuary 2009

  14. What’s about Occupational Exposure ?Structure (para. 3.62 – 3.106) 3. PLANNED EXPOSURESITUATIONS Scope Generic requirements Occupational exposure Public exposure Medical exposure • ScopeEmployers/Registrants/Licensees • Responsibilities WorkersCooperation between E,R or L • Areas (CA,SA, WP)Individual monitoring-Application of the system Exposure records for Protection and Safety Workers Health surveillance Education & Training PPESpecial compensatory arrangements • Conditions of service Female workers Alternative employment Conditions for young persons • Specific situations Crew in space based activities

  15. What’s about Occupational Exposure ? Scope • The requirements for occupational exposure in planned exposure situations given in paras 3.62 to 3.106 apply to occupational exposure due to a practice or source within a practice, as referred to in paras 3.1–3.3, or due to the performance of remedial work in an existing exposure situation, as referred to in Section 5. In the case of exposure to natural sources, such requirements apply, as appropriate, only to the occupational exposures specified in para. 3.4(a), (c) and (d).

  16. What’s about Occupational Exposure ?Changes • See “Scope” • 3.77 • 3.98 • 3.101 • 3.104

  17. Para 3.77 • {I.29} Employers, registrants and licensees shall minimize the need to rely on administrative controls and personal protective equipment for achieving protection and safety by maximizing the provision of well engineered controls and satisfactory working conditions, in accordance with the following hierarchy of prevention principles: • Engineered controls, • Administrative controls, • Personal protective equipment.

  18. Para 3.98 Education and training • {I.27 (a) (c) (d)} Employers, in cooperation with registrants and licensees, shall: • (a) Provide to all workers adequate information on the health risks due to their occupational exposure, whether normal exposure or potential exposure, adequate instruction and training on protection and safety and adequate information on the significance for protection and safety of their actions; • (b) Provide appropriate information, instruction and training to those workers who could be affected by or involved in the response to an emergency; • (c) Keep records of the training provided to individual workers.

  19. Para 3.101 • {I.27 (b)} Employers, in cooperation with registrants and licensees, shall provide to relevant female workers, such as those who are liable to enter controlled or supervised areas or who may undertake emergency duties, appropriate information on: • (a) The risk to the embryo or foetus due to exposure of a pregnant woman; • (b) The importance for a female worker of notifying her employer as soon as she suspects that she is pregnant [1]; • (c) The risk to an infant ingesting radioactive substances by breast feeding[1] Notification of pregnancy cannot be a requirement on a female worker in terms of these Standards, but it is something that she should do so that her working conditions may be modified accordingly.

  20. Para 104 Conditions for young persons • {I.19} No person under the age of 16 years shall be subjected to occupational exposure

  21. What’s about Occupational Exposure ? Schedule II DOSE LIMITS FOR PLANNED EXPOSURE SITUATIONS • II-1. For occupational exposure of workers over the age of 18 years, the dose limits are: • (a) An effective dose of 20 mSv per year averaged over five consecutive years; • (b) An effective dose of 50 mSv in any single year; • (c) An equivalent dose to the lens of the eye of 150 mSv in a year; • An equivalent dose to the extremities (hands and feet) or the skin [1] of 500 mSv in a year.[1] The start of the averaging period shall be coincident with the first day of the relevant annual period after the date of entry into force of these Standards, with no retroactive averaging.

  22. What’s about Occupational Exposure ? Schedule II DOSE LIMITS FOR PLANNED EXPOSURE SITUATIONS II-2. For occupational exposure of apprentices of 16 to 18 years of age who are training for employment involving exposure to radiation and of students of age 16 to 18 who are required to use sources in the course of their studies, the dose limits are: (a) An effective dose of 6 mSv in a year; (b) An equivalent dose to the lens of the eye of 50 mSv in a year; (c) An equivalent dose to the extremities or the skin [2] of 150 mSv in a year.[2] The equivalent dose limits for the skin apply to the average dose over 1 cm2 of the most highly irradiated area of the skin. Skin dose also contributes to the effective dose, this contribution being the average dose to the entire skin multiplied by the tissue weighting factor for the skin.

  23. Since June 2008 … • More than 1200 comments have been transmitted to the IAEA* • Mainly editorial issues • Some key issues to be addressed by thenext RASSC/WASSC meeting (…this week !) * Very relevant comments/proposals provided from ISOE BSS-WG through NEA channel

  24. Thank you for your attention
