The special name for the SI unit (J kg-1) of equivalent dose and eﬀective dose.
from ICRP Publication 119, 2012
The name for the SI unit of equivalent and effective dose; 1 Sv = 1 J kg-1.
from ICRP Publication 118, 2012
Doses in Gy are multiplied by a quality factor which depends on the particular detriment to obtain sieverts. The sievert should not be used in the quantification of radiation doses or in determining the need for any treatment in situations where tissue reactions are caused. In general, in such cases, doses should be given in terms of absorbed dose in [gray] (Gy), and if high-linear energy transfer radiations (e.g. neutrons or alpha particles) are involved, a relative-biological-effectiveness-weighted dose, RBE·D (Gy), may be used.
