     Denis,

     Whoa!!  Do you mean 35 mR/hr?? or is it "really" R/hr.  I've
yet  to  do  the calculations for 35 R/hr, but that's a  BIG  rod
source for Bi-207.

     A  source showing .6 R/hour wouldn't (in my experience) drop
.1R/hr  by putting a glove over it - especially Bi-207 with those
EC gammas.

I  have a Bi207 rod (2" long x ~0.125" dia.) of unknown activity.
I have
calculated an activity but want some backup. The particulars are:

Dimension as above

35 R/Hr on contact

0.6 R/Hr at 30cm

0.5 R/hr at 30cm with a 4mil nitrile glove covering source

used information from the RHH '70

I need to add this source to my license (state of PA) but want to
make
sure that it is listed correctly.

Thanks in advance.  Take a break from the admin and try this out.

PS this is not a test question
