Maximum and likely gamma were not significant predictors of risk for can- cer of the CNS, whereas background radiation was of borderline significance (p = 0.06).

For white females in Table 7, there was an increasing trend in SMRs for breast cancer across levels of increasing exposure to maximum gamma, although none of the individual SMRs were statistically significant (SMRs = 87.9, 104.2, 113.2, 117.9).
2000a) reported a borderline significant increasing trend in lung cancer risk with increasing nat- ural background radiation in males.
