Re[2]: I-125 gamma constant (correction)

[michael_coogen@hq2ccgw.hq.dla.mil]

     I have a 1970 edition of the Radiological Health Handbook.  The 
     formula gamma ray constant/10 = R/hr at 1m/Ci.  The gamma ray constant 
     for I-125 = approximately 0.7, therefore for I-125 it would be 
     0.07R/hr at 1 meter for one Curie....mike coogen

     The previous response was incorrect .. the result should be .07 R/hr 
     at 1 m/Ci
     
     sorry about that!

The revised edition of "The Health Physics and Radiological Health 
Handbook", edited by Shleien, copyright 1992, indicates that the specific 
gamma ray dose constant for I-125 is 7.432-5 (mSv/h)/MBq (or 0.274 mR/hr per 
mCi at 1 meter).  This is an order of magnitude greater than several other 
references I have.  Does anyone know of any errata issued for this handbook?
