Editing Equivalent dose (section)

===Use of old factors===
[[File:Neutron radiation weighting factor as a function of kinetic energy.gif|thumb|350px|The radiation weighting factor for neutrons has been revised over time, and is different for US NRC, and ICRP.]]
The [[International Committee for Weights and Measures]] (CIPM) and the US [[Nuclear Regulatory Commission]] continue to use the old terminology of quality factors and dose equivalent. The NRC quality factors are independent of linear energy transfer, though not always equal to the ICRP radiation weighting factors.<ref name=NRC1004 /> The NRC's definition of dose equivalent is "the product of the absorbed dose in tissue, quality factor, and all other necessary modifying factors at the location of interest." However, it is apparent from their definition of effective dose equivalent that "all other necessary modifying factors" excludes the tissue weighting factor.<ref>{{cite book|title=10 CFR 20.1003|year=2009|publisher=US Nuclear Regulatory Commission|url=https://www.nrc.gov/reading-rm/doc-collections/cfr/part020/part020-1003.html}}</ref>
The radiation weighting factors for neutrons are also different between US NRC and the ICRP - see accompanying diagram.
