SYSTEM OF RADIATION PROTECTION QUANTITIES USED FOR OCCUPATIONAL EXPOSURES TO EXTERNAL SOURCES: SHORT HISTORY AND CRITICAL REVIEW.

The article summarises the development of the system of radiation protection quantities used for occupational exposures to external sources throughout the last century. Although the current system generally meets the radiation protection needs quite satisfactorily, this system has often been the target of criticism. Some controversial issues are highlighted in the present paper. The conclusion is that it would be appropriate to undertake a deep review of the current system and suggest the necessary revisions to remove any ambiguities or confusion and address the deficiencies and incoherencies.
