Values applied in this study for tissue weighting factors, wT, from ICRP Publication 60 (ICRP 1991) and risk coefficients for incidence, IT/HT, and mortality, MT/HT, for 10 year olds from Tables 12D-1 and 12D-2 in the BEIR VII Report (NRCNAS 2006), listed in terms of absolute risk (in percent) per sievert of equivalent dose.

Blank values were taken as zero because they were not included in Tables 12D-1 and 12D-2 in the BEIR VII Report. Although specific risk coefficients were also available for cancers of the prostate and uterus, these SMN sites were neglected because the values of equivalent dose in these organs were minimal and the risk coefficients were small.
