ICRP 261 50 mSv (5rem)/yr

(108)2

5 mSv (0.5 mrem)/yr (119)

# 15 mSv (1.5 rem) Working condition B (116)

ICRP 60

20 mSv (2 rem)/yr, avged 5 yr

50 mSv (5 rem) in any year 100 mSv (10 rem) (total) in 5 yrs (166)

1mSv (0.1 rem)/yr Special circumstances of higher value, 5 yr average 1mSv 
(0.1 mrem) (192)

2 mSv (200 mrem) to surface of abdomen for remainder of pregnancy, limit 
intakes 1/20 ALI

(178)

ICRP 103

20mSv (2 rem)/yr, avged 5 yr 50 mSv (5 rem) in any year 100 mSv (10 
rem)(total) in 5 yrs (183)

1 mSv (0.1 rem)/yr Special circumstances of higher value, 5 yr average 1mSv 
(0.1 rem) (191)

1mSv (100 mrem) to the embryo/fetus (186)

Part 20

50 mSv (5 rem)/yr ('20.1201(a)(1)(i))

1 mSv (0.1 rem)/yr Up to 5 mSv (500 mrem)/yr with prior NRC authorization 
('20.1301(a)&(d))

5 mSv (0.5 rem) ('20.1208(a))

1 ICRP-2 was mentioned in the body of the Commission paper but not included 
in this comparison because it was fundamentally different than the other 
reports. The external limit for occupational workers was 5(N-18) rem, where 
N=the worker’s age. The internal dose was driven by the organ dose, which 
gave values of maximum permissible concentration based on organ dose rather 
than the effective dose. ICRP-2 did not contain any tissue or radiation 
weighting factors.

What was the first year and publication in which ICRP established the 1 mSv 
annual limit for members of the general public?
