Figure 7. Nuclear Worker Data for Leukemia Risk

Express relative risk for mortality for all leukemias, excluding chonic lymphatic leukemia, versus cumulative dose for 96,000 nuclear industry workers in the United Kingdom, the united States, and Canada. The error bars correspond to plus and minus one standard deviation. Forcing a straight-line fit to all of the data yeilds a relative risk factor of 2.15 x 10-2 per rem. However, if the highest-dose point is excluded, the remaining data show no increase dose. (Data from E. Cardis, et al., 1995, Radiation Research 142: 117-132.)
