• How far have the IAEA Code of Conduct and HASS been implemented?
• What feedback is there?  For example, what improvements to security and safety have been achieved? (and how have these been demonstrated?)
• In which sectors have there been problems with implementation?
• What further improvements might be made?
• Are existing controls on the import/export of sources (legal or illicit) effective?  What should be done at borders/monitoring stations to ensure that doses to persons are optimised?

2.  Balancing security and safety – how to achieve an optimum solution

• When justifying a particular practice, what account should be taken of the security requirements for the radioactive sources?  Should it be possible to prohibit certain practices because of concerns about security?  Or is there a danger that security requirements will discourage the safe use of radioactive materials?
• Is there a security equivalent to the ALARA principle?  For example “As Secure as Reasonably Practicable”?  If so, how is an optimum level of security achieved?  Or does a different principle apply?
• Is it important to link the cost of security measures with the potential savings in both dose and cost?  If so, how should this be done?
• Are there examples of where safety and security requirements conflict (for example, the posting of warning signs?).  If so, how should these be resolved?
• A balance is needed between information exchange (for safety purposes) and confidentiality (for security purposes).  How should this be achieved in practice?

• How should potential doses (public and worker) from malevolent acts be estimated?  And how can these doses be taken into account when establishing a safety/security programme?
• How should first responders/emergency workers be equipped and trained to help restrict their own radiation exposures?
• In the event of an emergency exposure situation, what practical arrangements should be in place to apply the ALARA principle, i.e. to restrict the doses received by workers and the public as the situation evolves?

4.  Justification and optimisation in the use of security devices

• What are the radiation protection issues associated with introduction of security-related screening of persons?
• How are such sources justified?  What criteria should be used to assess the potential benefit?  Is “security” always a sufficient justification?
• How should exposures (workers and public) be optimised?  What dose constraints are appropriate – for screened persons, and for operators?
• What criteria, if any, should be applied when deciding who should and should not be x-ray screened? What information should be given to persons that are screened?  What choices should they have?
