806 Table 2. Summary of annual deaths—5%leaving rate. The age-specific death rates in our steady state population of radiation workers and ex-workers. Columns C, D and E show the numbers of deaths expected among non-radiation workers on the basis of table 1. Columns F and Gshowthe predicted numbers of radiation induced deaths on the basis of A= 10-*rad-t and D = 1 rad/year for risk type A over 30 years (J*) and 50 years (G). Note: to find the expected number of radiation-induced leukaemia deaths, column F should be scaled by eqn (1) with an appropriate F& (e.g. 3x 107%) | B Population size Age IN 16-23 13 900 26-35 25 000 36-45 28 000 46-35 21 000 56-65 13 000 66~75 76-85 36-95 16-65 100 000 16-935 100 000 Total 15 000 37 000 33 000 57 900 52 000 214 000 271 000 Cc D E Al ICD nos.
