11. Issues requiring further work
Revision BSS Draft 1.0
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

12. Issues requiring further work
Revision BSS Draft 1.0
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.

14. What’s about Occupational Exposure ? Structure (para. 3.62 – 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

15. 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).

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 the next RASSC/WASSC meeting (…this week !)
* Very relevant comments/proposals provided from ISOE BSS-WG through NEA channel
