The following information was received from the state of
South Carolina via email:
On July 13, 2018 the Department [South Carolina Division of Health and Environmental Control] was notified by the licensee that it had discovered a
stuck shutter on one of its
gauges while performing a lockout procedure in order to do maintenance on a rotary valve located near the
gauge. The
gauge is a Kay-Ray Model 7462BP s/n 22425 containing 50 mCi of
Cesium 137. The licensee has contacted Systems Services who is specifically licensed to repair the damaged shutter. The
RSO [Radiation Safety Officer] stated that the
gauge is located 20 feet above areas where individuals normally work. The
RSO also surveyed the
gauge and found a reading of less than 2 mR/hr. Access to the
gauge is made via a catwalk which will be roped off by the
RSO until the service provider comes to fix the shutter. The service provider is scheduled to come July 17, 2018.
