Re[2]: I-125 gamma constant

[michael_coogen@hq2ccgw.hq.dla.mil]

     Probably a misprint.  The dose should be 0.07R/hr at one meter for one 
     Curie using the formula gamma ray constant (0.7)/10 = R/hr at 
     1m/Ci...mike coogen

     The Handbook, dated 1970 also shows the same info as you have listed. 
     On Page 131 the gamma ray constant for I-125 is .7 R/hr at 1 m/Ci

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?
