AW: [ RadSafe ] TLD Readings in Checked Luggage

[Doug Aitken]

I'm not sure that this is totally correct, given the vast range of 
inspection equipment being used around the world, including heavy dose 
X-ray machines in some less up-to date places. In the US (I guess this is 
the focus of Linda's query), we have seen some higher than normal doses on 
TLD (L!7) and OSL (Al2O3) badges that have been attributed to airport 
security scans. However, as these are quarterly badges of workers 
performing source manipulations, it is a little difficult to attribute 
actual doses to airport exposures. Perhaps Sandy can give some more 
coherent information?

Regards
Doug
