The National Radiological Protection Body (NRPB) personal monitoring service (PMS) has been a valuable source of data on occupational exposures of a large, though ad hoc, subset of UK radiation workers outside the nuclear industry. The Central Index of Dose Information is more comprehensive in its coverage and provides the definitive account of the doses incurred by classified workers. This article contains dose statistics for 1990 and provisional results for 1991. All the dose statistics presented have had notional dose replaced by the appropriate fraction of the measured dose. Notional doses are, however, becoming less common as employers are encouraged to make realistic estimates of missing doses rather than allowing notional doses to stand. -from Authors
