Palo Verde provides the following response:

Palo Verde uses the Bicron Micro Rem Meter and we calibrate on the X1 position 
using a Shepherd Model 89 Calibrator and expose the detector to a 150 μR/hr 
gamma field.

Subject: Powernet: MicroRem Calibration

Just a quick question.

Ginna calibrates our microrem meters on the x1 scale electronically instead of 
calibrating on that scale against a source.

We calibrate the other scales (x10, x100, x1000) against a source.

This method is authorized in the tech manual but was challenged.

What does your site do?

Thanks,

Bryan
