Controlling the number of measurements is the key to efficient surveys, which make the best use of limited resources. MARSSIM allows you to examine the factors that drive the number of measurements required:
- DCGL
- radionuclide concentration variability in the survey unit and background
- tolerable decision error rates
- identifying elevated areas
Consider changes to the survey design only after determining the reason a specific number of measurements is suggested.
