Use of personal monitors to estimate effective dose equivalent and effective dose to workers for external exposure to low-LET radiation

This report prepared under the auspices of Scientific Committee 46, a scientific program area committee of the National Council on Radiation Protection and Measurements (NCRP) concerned with operational radiation safety, provides practical recommendations on the use of personal monitors to estimate effective dose equivalent (HE) and effective dose (E) for occupationally-exposed individuals. The report is limited to external exposures to low-LET radiation. Recent additions to the radiation protection literature have made the recommendations possible. In order to avoid delay in utilizing the recommendations in the United States, the quantity HE, as well as E, has been included until such time as the federal radiation protection guidance and associated implementing regulations are revised to express dose limits in E as recommended by the NCRP
