IAEA Revision of BSS SS115 International Basic Safety Standards for Protection against Ionizing Radiation and for the Safety of Radiation Source Status of revision: draft 0.8 International Cooperation with WHO, PAHO, FAO, ILO, OECD/NEA, EC, UNEP, ICRP, IRPA

IAEA BSS revision background The current Draft 0.7 is based on The current Draft 0.7 is based on: ●Initial topical drafting meetings that were completed in May ●Collation of the drafting group material by the IAEA Secretariat. ●The recommendations of a Technical Meeting (TM) held in Vienna from July 2007

IAEA ●Additional advice from a meeting of Cosponsoring Organizations from 3-4 September 2007 ●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 May 2008 BSS revision background

IAEA 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 Revision BSS - Draft 0.8

IAEA 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 Revision BSS - Draft 0.8

IAEA 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. Revision BSS - Draft 0.8

IAEA 4. Emergency Exposure Situations Scope Generic Requirements Public exposure Exposure of emergency workers, Transition from emergency exposure situation to existing exposure situation Revision BSS - Draft 0.8

IAEA 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 Revision BSS - Draft 0.8

IAEA 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 Revision BSS - Draft 0.8

IAEA Issues requiring further work 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 Revision BSS - Draft 0.8

IAEA Issues requiring further work 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. Revision BSS - Draft 0.8 Glossary BSS within the Long term structure of Safety Requirements

IAEA BSS revision: milestones ●End June 2008 – completion of Draft 1.0 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 ●Workshop on Revision of BSS in Qatar, 1 – 3 December 2008

IAEA What’s about Occupational Exposure ? Structure (para – 3.106) 3.PLANNED EXPOSURE SITUATIONS Scope Generic requirements Occupational exposure Public exposure Medical exposure -Scope Employers/Registrants/Licensees -Responsibilities Workers Cooperation 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 PPE Special compensatory arrangements -Conditions of service Female workers Alternative employment Conditions for young persons -Specific situations Crew in space based activities

IAEA What’s about Occupational Exposure ? Scope The requirements for occupational exposure in planned exposure situations given in paras 3.62 to 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).

IAEA 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[1];[1] (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; (d)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. [2] [2] The equivalent dose limits for the skin apply to the average dose over 1 cm 2 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.

IAEA What’s about Occupational Exposure ? Schedule II DOSE LIMITS FOR PLANNED EXPOSURE SITUATIONS OCCUPATIONAL EXPOSURE 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.
