===Naming conventions===
The ICRU/ICRP dose quantities have specific purposes and meanings, but some use common words in a different order. There can be confusion between, for instance, ''equivalent dose'' and ''dose equivalent''.

Although the CIPM definition states that the linear energy transfer function (Q) of the ICRU is used in calculating the biological effect, the ICRP in 1990<ref>ICRP publication 60 published in 1991</ref> developed the "protection" dose quantities ''effective'' and ''equivalent'' dose which are calculated from more complex computational models and are distinguished by not having the phrase ''dose equivalent'' in their name. Only the operational dose quantities which still use Q for calculation retain the phrase ''dose equivalent''. However, there are joint ICRU/ICRP proposals to simplify this system by changes to the operational dose definitions to harmonise with those of protection quantities. These were outlined at the 3rd International Symposium on Radiological Protection in October 2015, and if implemented would make the naming of operational quantities more logical by introducing "dose to lens of eye" and "dose to local skin" as ''equivalent doses''.<ref name="endo" />

In the [[United States|USA]] there are differently named dose quantities which are not part of the ICRP nomenclature.<ref>[http://www.wmsym.org/archives/2009/pdfs/9444.pdf "The confusing world of radiation dosimetry"] - M.A. Boyd, U.S. Environmental Protection Agency 2009.
