Excess relative risk (ERR) estimates from the A-bomb survivors and from selected studies of persons exposed to protracted low-LET external ionizing radiation.

* Doses are external colon dose in mGy for Mayak workers, weighted colon dose in mGy for the atomic bomb survivors, Hp(10) in mSv for the 15-country and NRRW studies.(Hp(10) is the equivalent dose at a tissue depth of 10 mm beneath a dosimeter); stomach dose in mGy for the Techa river cohort
† 90% confidence intervals used for comparison with published results in the 15-country and NRRW studies
†† weighted average with weights of 0.75 for men and 0.25 for women to reflect the sex ratio in the Mayak worker cohort
‡ These populations are predominantly male
§ The estimate presented here is based on the 15-country study results withwith the Canadian data excluded ([29], page 405).). This estimate was used because of concerns about the Canadian data usedused in that study. This concerns have beenbeen supported by the recently published re-analysis of the Canadian workerworker data given in [34]. The ERR/SvSv estimate for using all of the 15-country data is 0.59 (95% CI <0 to 1.5, [29], page 403).
** There was no evidence that risk differed by sex in this cohort.
