Over the years, the International Commission on Radiological Protection (ICRP) has created a variety of weighted expressions for radiation dose. In 1977, the ICRP introduced an unnamed summation that was to be compared to an applicable limit:
 | (1) |
where
wT is the tissue-weighting factor for tissue
T;
HT is the dose equivalent to tissue
T; and
Hwb,L is the recommended
annual dose equivalent limit
(1). This summation was later named
‘effective dose equivalent’ in Publication 28
(2).
Also in ICRP Publication 26, as modified in Publication 28,
was a statement that the limits would be satisfied if, for an
individual receiving doses from ‘external and internal
exposure’, the ratio of the deep dose equivalent to the
dose equivalent limit plus the sum of intakes divided by intake
limits should be less than 1:
 | (2) |
where
HI,d is the annual deep dose-equivalent index,
HE,L is the annual
dose equivalent limit,
