ERRed/Gy denotes an excess relative risk per 1 Gy of stomach absorbed dose from external gamma rays;
ERRid/cGy denotes an excess relative risk per 1 cGy of absorbed dose from internal alpha particles for monitored workers;
ERRsur denotes an excess relative risk in categories of surrogate dose for non-monitored workers;
W denotes that an estimate was based on Wald’s statistics if an bound of a confidence interval was not defined;
* denotes that the category included only male workers.
