1. Scope
1.1. The provisions of this code apply to all activities involving the exposure of
workers to ionising radiations1 at work. Additional guidance can be found in documents
dealing with special occupational groups and working situations.2
1.2. The provisions of this code offer guidance for the protection of workers
against radiation risks from radiation sources at the workplace.
1.3. The code covers the principles of dose limitation for workers but it does not
include detailed guidance on the techniques used for the actual measurement and
assessment of exposures and for their control. Such guidance is being prepared by the
International Atomic Energy Agency (IAEA) in co-operation with the World Health
Organization (WHO) and the ILO.
1.4. It should be kept in mind, however, that the choice of techniques for control
of doses to workers should be made while taking into consideration the presence of
other, possibly more serious, chronic or acute risks in the workplace. It is therefore
important that actions taken to reduce radiation doses at a workplace should not be such
as to increase other occupational safety or health risks.
1.5. The provisions of this code are based on the current recommendations of the
International Commission on Radiological Protection (ICRP) and on Basic safety
standards for radiation protection.3
