In 2023 the IAEA published two new guidance documents, one on Clearance and one on Exemption. These documents explain the application of the principles of exemption and clearance in more detail. They also give guidance on the derivation of exemption and clearance levels for specific situations, for example surface contaminated objects. Importantly, they do not change the general exemption and clearance levels which are specified in the 2014 IAEA Basic Safety Standards and the 2013 EC Basic Safety Standards.  IAEA is currently developing a methodology for calculating specific clearance levels for different materials e.g., for metals for recycling, for concrete for recycling, for combustibles for incineration, and for landfill disposal of contaminated slags and dust. Specific clearance is an important concept that directly supports a sustainable approach to decommissioning and clean-up.

This webinar describes the key concepts of exemption and clearance and the new IAEA guidance, highlighting any implications for UK.
