The scan MDC values that can be calculated on this webpage are generated with a “probabilistic method” as described by Alecksen and Whicker (2016) in the Health Physics journal. This method was designed specifically for GPs-based gamma surveys that employ commonly used sodium iodide (NaI) scintillation detectors. The reference for citation of the method or any scan MDC values calculated from this webpage is as follows:

A White Paper which provides a technical overview of the probabilistic method for calculating scan MDCs and how this online calculator generates respective values can be found under the “Resources” links below. This White Paper is limited in scope and is provided as a courtesy to users of the scan MDC calculator. Any citation/referencing of the probabilistic method or respectively generated scan MDC values should cite the article in Health Physics as noted above.
