COLORADO AGREEMENT STATE REPORT: REMOVABLE SURFACE CONTAMINATION ABOVE LIMITS
Removable surface contamination test on two sealed sources removed from the same instrument exceeded the 0.005 microCuries limit specified in RH 4.16.5. The first source is a Nickel-63 source, serial number F6499, activity: 13,200 microCuries, activity reference date: 08/31/93, Instrument ID: ECD1, swipe test results - 0.031 microCuries. The second source is a Nickel-63 source, serial number F2069, activity: 13,200 microCuries, activity reference date 05/29/91, Instrument ID: ECD1, swipe test results - 0.018 microCuries.
"The sources were immediately removed from use and the instrument tagged 'out of service.' The usual vendor for cleaning and re-certification of the ECD sources was contacted and is considering options for repair or replacement. The sources will remain under the control of the Radiation Safety Officer until this determination is made. A decision will likely be made within two days, as the repair of the affected instrument is a high priority.
"Additionally, the cabinet that houses the sources in the instrument was swiped, as well as the employee's workstation in the immediate vicinity. These tests showed no removable contamination above the method detection limit of 50 picoCuries."
Colorado Report # I04-20.
