What are Occupational Radiation Protection Appraisal Service (ORPAS)?
ORPAS missions are conducted as an independent appraisal service in the field of radiation protection of workers. Such an appraisal is an opportunity for a Member State to have all or some aspects of its occupational radiation protection programme independently assessed and evaluated against international safety standards. The purpose of the assessment is to check the legislative and regulatory infrastructure and practical implementation of a state’s occupational radiation protection programme.

ORPAS is appraisal service provided by the IAEA to facilitate the application of, and perform reviews against, IAEA Safety Standards in Member States. Unlike any other mission, ORPAS missions not only focuses on the regulatory elements of a Member State but also on end users and Technical Services/Support Organizations that will participate in the appraisal process. In addition, missions are conducted in an environment of close cooperation and communication with Member States, with a view to enhancing the ownership of ORPAS recommendations.
What does ORPAS cover?
ORPAS is appropriate for all types of facilities and activities. It also covers the regulatory authority, end users, technical service providers, and technical and scientific support services or organisations (TSOs) for protection and safety in respect to the assessment of occupational exposure from external sources of radiation and due to the intake of radionuclides. 

It includes individual monitoring, as well as workplace monitoring, and advisory services.  ORPAS promotes self-assessment, safety culture in radiation safety environment and quality systems at facilities and activities. Read more >>

How does it work?
The assessment is conducted by international experts that are selected based on their experience with such reviews, as well as for their knowledge of international guidance and best practices. They should be also able to recognise and understand the features of different national radiation safety systems and arrangements.

The expert team concludes its review with a final report that identifies recommended improvements and actions. Read more >>
