RE: TLDs as Anti-Theft Devices?

["George J. Vargo" <vargo@physicist.net>]

John,



Sandy is quite right about NOT taking dosimeters off site.  I have been

involved in cases where the TLD was accidentally exposed in a non-work

setting and caused a LOT of trouble.  Some of these have involved dosimeters

in proximity to NORM, electronic devices (low-energy x-ray leakage) etc.  It

is a poor practice and merely a matter of time before it bites you.

Sandy,



Thanks for the response.  I'm sure if this ever happened before that you

would be the first one to hear about it.  I'll try your second suggestion of

taking a few TLDs to Wal-Mart to see if I can reproduce the problem. Agree

with your first suggestion but upper management here feels that any

potential problems are outweighed by the benefits of allowing workers to

take home their TLDs.

There isn't much to a TLD. You have the holder, which has a metal clip, the

TLD card itself and the filters in the holder. Most anti- theft dtetctors

work off of some type of an encoded device attached to the item the store is

trying to protect. Perhaps the bar-code on the TLD label somehjow matches

the ID frequency that the unit is looking for. Perphaps it's the meta clip,

but then cellphones should set-off the detector.



Suggestion.. the individual shouldn't be enetering these stores with their

TLD. More reason for not taking home dosimetry in the first place.



2nd suggestion .. take some other TLDs and see if they too set-off the

detectors. Maybe this person is setting off the alarms.



Comment .. if the TLD is really the culprit, I'd expect to hear about more

issues out there.



I'd like to hear the resolution, if one is found.
