Yes 2) How and when is this testing conducted? Prior to initial issue of their TLD with a DMC-2000S tester. Additionally, most radiation workers are tested annual for hearing. 3) Do you challenge a workers ability to hear Direct Reading Dosimeter alarms in a high noise background area when using an enhanced alarming dosimeter such as a PAM 1 or PAM-TRX? No, workers are instructed to don hearing protection and then tested with the DMC-2000S tester to evaluate hearing the DAD alarms. 4) Do you test outage workers during Radiation Worker initial training? Yes 5) What measures do take if a worker fails the hearing challenge test? We require the use of an alternate alarming device (PAMs, LEDs, remote monitoring, etc.) Thanks In Advance, Ray Thomson Health Physics Staff Advisor Columbia Generating Station [email protected] Office, 509-377-8273 Pager, 509-780-0339 CONFIDENTIALITY NOTICE: This electronic message contains information which may be legally confidential and/or privileged and does not in any case represent a firm ENERGY COMMODITY bid or offer relating thereto which binds the sender without an additional express written confirmation to that effect.
