Direct Reading Dosimeters - Leak Checks, Good Practices

[CHASE John -NUCLEAR <john.chase@ontariopowergeneration.com>]

1.	A question has come up in our stations about how often to perform
leak checks on DRDs. The manufacturer says they should be done monthly, but
industry practice is every 6 months or every year, after the initial leak
check. Does anyone know the basis of the manufacturer's recommendation for
monthly checks, or the basis for less frequent checks.
2.	Does anyone have references/information on good programs for
managing DRDs?

Thanks in advance
