  • ND curb Notes: 1) Only results greater than the MDC are reported herein. ND therefore indicates that the analytical result was below the MDC and typically also VCFD ND represents real groundwater sampling results where the radionuclide activity level is either positive but very low and unquantifiable, or not VCFD detectable above background, its exclusion results in a high bias to the average and thus adds a measure of conservatism to the subsequent dose A/C Notes: Grass
