Subject: Powernet: Dropped EDs causing Dose Rate Alarms

Please categorize the volume of dose rate alarms attributed to "dropped" EDs:

(1)    Infrequent (< 20%)

(2)    Occasional (>20% and <40%)

(3)    Frequent (>40%)

Also, do you review each histogram for unexpected dose rate alarms?

Thanks for your response.
