Re:: Dose rate constants

[baumbaug@nosc.mil (Joel T. Baumbaugh)]

     Boy, I hope that I don't get too pounded for this one,

     but,

     As  most,  if  not  all  of you know, when  you  look  at  a
full/detailed  decay  scheme  of  many  radioisotopes,  including
I-125, there is a LOT going on (i.e. x-rays as well).

     The  original  Radiological Health Handbook (last  published
Jan.  1970)  gives a "Gamma" constant for I-125 at  approximately
.07  R/hr at 1m/Ci.  This may be a true number for the gammas and
only the gammas and may not include the plethora of x-rays...

     However,  I am so used to taking the information in the "old
book"  as tried and true, that I find it hard to put credence  in
the  younger  come-up-en's numbers... I'd sure like to  see  some
real  experimental  evidence  on this and other  gamma  constants
(excuse me, dose rate constants).
