RE: (extremity dose)

["Moroney, Roger W" <Roger.Moroney@mkg.com>]

Another excellent article is in "Nuclear Medicine Communications", 2000, 21,
511-519, by Dhanse, Martin, Hilditch and Elliott. It is titled, "A Study of
doses to the hands during dispensing of radiopharmaceuticals". It compares
dose rates from syringes, with and without, syringe shields at differents
locations on each finger and looks at the modification to the source term at
different points which was caused by the syringe shields themselves. A very
comprehensive experiment.

The Journal of Nuclear Medicine Technology Vol 9, No.2 pg 91-98 "Fingertip
and Whole Body Exposure to Nuclear Medicine Personnel" by George Lis, Said
M. Zu'bi and Suresh M. Brahmavar is an interesting paper on fingertip
exposure.

Although the paper itself is 20 years old, the models seem pretty relevant
today. The authors suggest that the fingertip dose is 6 to 9 times the ring
dose.   For those concerned with extremity doses, this paper may be
considered quite useful. The calculations and measurements of unshielded
Tc-99m doses based on volume alone could save one much effort in dose
reconstruction situations.
