(info) The development of assessment approaches for application in environmental radiological assessements has been moderately rapid over the last decade (2000-2010). As a consequence comparatively recent outputs have been superseded. Whilst these 'older' outputs are openly available their replacements should be used by preferences. However, we recognise that it may not be obvious to all users which approaches have been superseded, here are the ones we are aware of:


(warning) Assessors should NOT use these superseded approaches unless they can thoroughly justify their application (e.g. the use of the EA R&D128 model would be justified for releases of noble gases to the atmosphere as this is the only approach to consider these radionuclides)(warning).

If you have outputs that you would like to have included within these pages please let us know (email:
