What is a Derived Concentration Guideline Level (DCGL)?
The Derived Concentration Guideline Level (DCGL) is a radionuclide-specific surface or volume residual radioactivity level that is related to a concentration or dose or risk criterion. The regulator usually determines this criterion. The DCGLW is a reference criterion, or radioactivity level for residual radioactivity evenly distributed over a large area. The DCGLEMC (“EMC” stands for elevated measurement exposure) is used when small areas of elevated radioactivity exist within larger areas.
