From: Liesl K Germann <[email protected]> To: "[email protected]" <[email protected]> Date: 02/26/2012 03:34 PM Subject: Powernet: EP Instrument Source Checks Sent by: [email protected] Do you apply the below ANSI N323A-1997 Section 4.8 statement regarding source response checks to your Emergency Planning instruments? 4.8 Source response check To ensure proper operation of the instrument between calibrations, each instrument (with the exception of neutron instruments and high-dose equivalent rate photon instruments) shall be checked with a source during operation at least daily or prior to each intermittent use, whichever is less frequent. If at any time the instrument response to the source differs from the reference reading by more than 20% (for any photon instrument the reading should be at least ten times background), the instrument shall be returned to the calibration facility for calibration or for maintenance, repair, and recalibration, as required. [ ...] Reference readings should be obtained for one point on each scale or decade used. Thank you!
