Frequent Questions

What is the relationship between survey unit size and the establishment of the DCGLW?

If the DCGLW was derived by environmental pathway modeling, then as the survey unit size changes in the model, the DCGLW may change too. Several factors affect this relationship, including the radionuclides of concern, the potential exposure pathways, and the uncertainties inherent in the model. Therefore, when considering changing the survey unit size, it is best to work with an experienced environmental pathway modeler to fully account for all the complexities inherent at your site. These changes may or may not affect the survey design. These changes may or may not affect the survey design. It is important to talk with your regulator to determine if the resulting changes have significant impact on the DCGLW previously agreed upon with your regulator.
