Infrequent.
Yes. A histogram is printed for all alarms
Our dropped ED incident was higher. Implemented a double attachment that
has resulted in almost none. The dropped ED alarms that do occur are
because the worker didn't secure the ED as trained.

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.
