| Title | Unplanned Contamination |
| Event Description | The following information was provided by the New York State Department of Health (NYSDOH) via email:
NYSDOH received a call from the radiation safety officer of NRD on May 8, 2024, regarding a worker that had detectable amounts of contamination on their hand upon exiting a restricted area (smoke detector assembly). [The smoke detector assembly] area is not classified as an airborne radioactive materials area therefore the only personal protective equipment (PPE) required is coveralls, booties, gloves, and dust masks (to [discourage] touching of mouth/nose with gloved hands). Additionally, there is no continuous air monitoring in these areas. The individual had surveyed themselves upon leaving the assembly lab (Am-241 would be the target isotope) and it was determined that only one hand (dominant hand) had been contaminated. The contamination on their hands was determined to be 242 disintegrations per minute per one hundred centimeters squared (DPM/100cm^2). Following detection, the individual underwent a full body frisk and survey by environmental health and safety and underwent nasal swabs, all of which returned results below background. The individual will be placed on special bioassay collection as a confirmatory measure. Following the detection of contamination on this individual's hand, they were instructed to wash and scrub the affected areas on their palm and fingers. Following this decontamination, the individual was resurveyed and the surveys showed that the contamination had been successfully removed. NRD, LLC was able to interview the individual and discovered that upon leaving the assembly lab, the worker had doffed PPE, including gloves, and removed a layer of the sticky mat for the room with their bare hands. Following removal and disposal of the sticky pad layer, the individual surveyed their hands and feet which led to the discovery of contamination on their hands. NRD, LLC performed a large area removable [contamination] survey of the area in which this event occurred and found no contamination in excess of action limits requiring decontamination. Urinalysis results (24-hour cumulative collection) indicated undetectable concentration of Am-241 in the individual's urine, therefore no intake was suspected from this event. NRD's investigation determined that the cause of this event was improper following of procedures by the worker. Corrective actions included retraining of the employee and other staff within smoke [detector] assembly [area]. This incident is now closed. NY Incident Number: 1484 |
