Abstract
AbstractThe present IAEA Transport Regulation on surface contamination (with limits specified in terms of Bq cm–2) is determined from a simple radiological model for the most hazardous radionuclides (Pu-239 for α emitters and Sr-90 for β emitters) and its extremely conservative model is applied for all other α and β emitters. In the International Atomic Energy Agency (IAEA) TECDOC-1449 report, the effect of radiation from non-fixed contamination on packages is evaluated and the dose conversion coefficients [(mSv/y)/(Bq/cm2)] are calculated for each radionuclide. In this study, exemption levels for surface contamination are calculated with the dose conversion coefficients specified in TECDOC-1449. The dose criterion for deriving the exemption level is chosen to be 0˙01 mSv/y, to maintain consistency with fundamental concepts adopted by the IAEA safety standards committees, namely, the Radiation Safety Standards Committee (RASSC), the Transport Safety Standards Committee (TRANSSC) and the Waste Safety Stand...
