title: Errors in applying the NSD concept.
abstract: An analysis of selected papers in which the Nominal Standard Dose (NSD) concept is used reveals that about 50% of them contain errors. These mistakes are both conceptual and mathematical in nature and average plus or minus 7%. Typical errors and methods to eliminate them are discussed. A table is provided for interconversion of NSDs, partial tolerances, and time, dose and fractionation (TDF) factors.
