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?
