Title	Source Recovery Malfunction
Event Description	The following is a summary of the information provided by the Washington State Office of Radiation Protection via email: On 6/22/23 at 1419 PDT, the licensee identified that a 56.4 Ci Ir-192 radiography source could not be retracted into the exposure device (QSA Model 880D) due to a crank malfunction. The radiographer immediately contacted the Radiation Safety Officer who provided source recovery/retrieval actions along with crank mechanism fixes. The radiographer secured the source in the exposure device at 1422 PDT. The problem with the retrieval was identified as a loose securing nut that caused the crank to spin freely and the drive cable to come out of the crank conduit. During the incident, the radiographer's survey meter read 20 mr/hr at the crank location. A radiographer assistant expanded the boundaries and ensured the general public was not affected. The radiographer's total direct dosimeter reading after 6 normal radiography exposures and the source recovery actions were complete was 3 mRem. The incident took place at a temporary job site in Anacortes, WA. There were no overexposures or spread of contamination. WA Incident Number: WA-23-010
