to reduce its recommended dose equivalent limit for the lens of the eye from 0.3 Sv to
0.15 Sv in a year, values of DAC for 81Kr and ‘3mKr are amended as follows.

Page 78, The values of ALI and DAC for 80Sr are incorrect because no allowance was made-for
the contribution to committed dose equivalent of *ORb, the daughter of 60Sr. The corrected
dosimetric data are given in Supplement B of Part 3. The correct values of ALI and DAC are
given below:
