Columbia's guideline is Direct-reading dosimeters (DRDs) should be read immediately upon issue, every 15 to 20 minutes when in a radiation area, and upon exit from the RCA. They should be read more often when in higher dose rate areas or where dose rates could change quickly.

Although we haven't set a procedure bound frequency for HRA's, the standard is every 5 minutes. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Thompson, Dewey L Sent: Tuesday, November 12, 2013 2:32 PM To: [email protected] Subject: Powernet: Benchmark - How often do you require your Radworkers to read the Electronic Dosimeter GREETINGS.
