Sigma projetor manual Annual Maintenance for the Model 880 Series Exposure Devices

Page 37

MAINTENANCE INSTRUCTIONS

The analysis performed on the wipe test must be capable of detecting the presence of 0.005 µCi (185 Bq) of radioactive material on the test sample. If the test sample reveals 185 Bq (0.005 µCi ) or more of removable DU contamination, the exposure device must be removed from service until an evaluation of the wear on the ‘S’ tube has been made. Should the evaluation reveal that the source tube is worn through, the exposure device may not be used again.

DU shielded devices do not have to be tested for DU contamination while in storage and not in use. Before using or transferring a device that has been in storage for more than 12 months, the exposure device must be leak tested for DU contamination prior to use or transfer. Please contact a QSA Global, Inc. service center if you require leak test kits, radio-assay services or assistance in the disposal of worn through exposure devices.
