Subject: Powernet: Number of hand held meters for a given plant

Greetings All,

I am trying to determine how many instruments are maintained for use at a 
typical nuclear station.  If you could give numbers for the listings below for 
your station that would be great.  I will make the averages available for 
anyone interested.  I don't need a probe breakdown or models, just approximate 
numbers (SWAG's OK).

PCM's (beta/gamma portal monitors like a PCM1B or PCM2 or other): 4
Hand and Foot Monitors: 3
Gamma Portal Monitors (like a PM-7 or other): 6

Hand helds
Dose Rate (meters with internal probes or those that use external probes for 
dose rate): Non Outage: 5-10  -   Outage: ~30
Count rate: Non-Outage: ~25  Outage ~50

Lab counters
Count rate: Non-Outage: 3 Outage: 4
Gamma Spec: 3

Thanks,

Rob
