Re: Electronic Dosimter's use for pan/ceph dental X-ray unit

Vaidy,

I have seen performance test results for these type of dosimeters from 
the intercomparisons performed at Oak Ridge a few years ago (PDIS 1 and 
2).  The electronic dosimeters did poorly with X-rays.  Maybe there have 
been improvements, but the problem had to do with the battery energy 
required to perform accurately with low E photons.

If you were more interested in just looking at response, and you could 
perform your own calibration they may be useful.  Of course you could 
also use a standard ionization chamber and be a bit more confident in 
the number you were getting (assuming it's calibrated for the energy you 
are assessing).

Good luck

Rob Gunter
