Description
At present, there are too many quantities used in radiation protection, which are causing some problems and inconsistencies in the presentation and interpretation of results from radiation detection and monitoring. Furthermore, the definition of these quantities is rather complicated and difficult to understand, especially for those entering the field. Another problem is the availability of only two basic units, namely Gy (grey) and Sv (sievert). This is causing a lot of confusion, since radiation exposure levels are usually given in these units without clearly specifying to which quantities they correspond. It would also be appropriate to strictly apply a unit of Gy.Eq for deterministic health effects. The paper presents an overview of current radiation protection quantities and proposes reducing their number and strictly distinguishing the use of units for stochastic and deterministic effects.
