[ RadSafe ] FW: OSL/TLD Comparison Experience

[Perle, Sandy]

Dan,

Please also address angularity, linearity, how variable the two technologies compared, time of irradiation until read, location of dosimeters, etc. You don't provide any data to make a evaluation and/or conclusion. What is right, what is not, perhaps the whole set were incorrect. More details please.

Thanks,

Sandy Perle

Hi All.  I just realized that I misstated the facts in my original post.
What I meant to say was that the OSL results have been higher (not
lower) than the TLD results in some departments.  Sorry about the
miscommunication.

Hello RadSafers.  Our plant (nuclear medicine production involving both
reactor- and accelerator-produced isotopes) is seeing significantly
lower results using OSL badges vs. TLD badges, but only in some
departments.  For other departments the results are virtually the same.
Has anyone else had similar experiences at their facilities?

I know the 'dosimetry bunch' will enjoy kicking this one around.

Please feel free to contact me offline if you prefer.

Thanks.

Dan Hoffman
