Smoke Detector, contamination, radioactive material. A review of the ORPS data base identified two other occurrences which indicate problems with smoke detectors. When handling smoke detectors containing radioactive sources, care should be taken not to damage the detector, which could result in a loss of the source's integrity. Consideration should also be given to the age of the detector and the environment in which it is installed. Facilities having these types of detectors should consider including this information in maintenance procedures used to service these types of smoke detectors to warn against a potential contamination hazard and to require radiological surveys before and after handling these types of detectors.
