Specific gamma-ray dose constant for 137Cs

[Michael McNaughton <mcnaught@LANL.GOV>]

I cannot reproduce the specific gamma ray dose constant for Cs-137 in the 

Rad Health Handbook (Table 6.2.2 of the 3rd edition or Table 6.1.2 of the 

1992 edition). I think it is about 10% too high. Could it be that Unger and 

Trubey forgot about the internal conversion of Ba-137m (which happens in 

10% of the decays)? I would appreciate any insights.
