NORM Field Sampling Plan: Surface Contamination Measurements Mobile App
Total (fixed plus removable) contamination shall be measured by direct survey with portable radiation survey instruments sensitive to beta/gamma radiation (e.g., pancake Geiger-Mueller detector, or equivalent) or alpha radiation (e.g., alpha scintillation detector), or equivalent).
How does it work?
The instrument shall be turned on and permitted to stabilize for a minimum of 30 seconds) prior to performing surveys. Use the checklists in the NORM Field Sampling Plan: Surface Contamination Measurements mobile app for checking Total Contamination on Surfaces, Pre Operational Checks, Radiation Survey for Total Activity on a Surface and Survey Methods for Determining the Extent of Removable (Loose) Contamination on Surfaces.
