RE: Ring dosimeter problems

["Medora, Riasp" <Riasp.Medora@fernald.gov>]

The finger dosimeters described here were/are made by a company called Thomson and Nielson in Canada. Their number ( Four years old) is (613) 596-4563. If I remember correctly it an electronic dosimeter not a TLD based.

Several years ago I remember seeing a finger dosimeter 

that was embedded in a plastic finger sleeve that fit 

over the top of the finger.  They were very flexible and 

fairly strong.



I don't know if they were ever released commercially 

(anybody know???), but if so, they might be a good 

substitute for rings.



I have also seen bare Harshaw TLD chips mounted to 

surgical gloves (light shielded with plastic, then taped 

to the inside of a glove) used with some success, but 

this is a real hassle to set up and won't work as a 

routine programatic approach.
