Appendix A: Derivation of Clearance Levels

Part of the An Advanced Course in Nuclear Engineering book series (ACNE)


Like the derivation of exhaust air and waste water radioactivity concentration limits based on the reference dose values for radiation protection, clearance levels are derived by following these steps:


Coarse Aggregate Radioactivity Concentration Exposure Scenario Irrigate Soil Evaluation Pathway
