To all

I have talked to the Rad Con group about the time delay after the time 
beam goes off and the time the beacon turns off. We do have a elevated 
reading at the last sensor in the string in the down stream tunnel. the 
threshold has been changed from 2.5mR to 2.89mR to see if that will help 
on the delay.  DOUG
