| Title | Density Gauge Source Found |
| Event Description | The following was received from the Florida Department of Health (the department) via email:
[The Radiation Safety Officer] from Mosaic Fertilizer called at 1130 EDT this morning to report a failed fixed density gauge on a pipeline. They reported that an employee found a [5 mCi Cs-137] sealed source on the ground, picked it up, held it in their hand for anywhere between 30 to 60 seconds before realizing what it was, then dropped it and reported it to management. The source was transported in an empty bucket and placed on a shelf in the onsite RAM [(Radioactive Material)] storage cabinet. The department's Materials Licensing was notified and will be sending out an inspector as soon as possible to conduct an immediate onsite inspection. The NRC was also notified. Source Assay Date June 2009. The following additional information was obtained from the department in accordance with Headquarters Operations Officers Report Guidance: Based on the information provided, the department calculated 1.42 R dose. They shared the information with the Radiation Emergency Assistance Center/Training Site (REAC/TS), which calculated 2.24 R dose, with no decay correction. It was determined that no medical attention is required. Florida Incident Number: FL22-062
The following was received from the Florida Department of Health (the Department) via email: Decay corrected calculations done by Bureau of Radiation Control, and verified by REAC/TS [Radiation Emergency Assistance Center/Training Site], for a 30 second dose to the hand was 1.42 R. (Contact dose rate constant to the hand of 770 R/min/Ci x 1 min/60 sec x 0.0037 Ci x 30 sec = 1.42 R) REAC/TS calculation = 2.24 R w/no decay correction. REAC/TS comments: there was very little to no medical concern, just observe the employee's hand. The Radiation Safety Officer [was] notified the morning of 6/8/22 of the inspectors' findings, dose calculation results and REAC/TS comments. Notified R1DO (Greives) and NMSS Events Notification via email. |
