Re[2]: Answers to Electronic Dosimetry Operability Checks

     We have the readers check for the chirp and do not see any "false 
     reportings".  Maybe our software or hardware has been modified to 
     correct a prior problem in this area.  In fact, we have added a 
     feature: if the worker pulls the dosimeter out prior to all the 
     information being tranferred, the dosimeter will alarm continuously.  
     This works quite well for those a little to anxious to get to work.

MG readers will check for the chirp, but the reliablity of the hardware that 
determines whether it chirped is really poor, you get about 10% false 
reportings that the dosimeter did not chirp.  This makes the checking pretty 
much useless in a production environment.  I stopped having the software 
check for chirps, because 10% of the people couldn't get in the plant.
