Re: Tc-99m Dose

[R.Smart@unsw.edu.au (Richard Smart)]

A couple of the best references for patient doses from radiopharmaceuticals
are ICRP 53 and ICRP 62. 

ICRP 62 lists the effective dose from Tc-99m-phosphates as 5.8E-03 mSv/MBq.
For individual organ doses use ICRP 53.

estimate for dose from injected Tc-99m used in bone scans.
