Title	Contamination Event
Event Description	The following information was received via email from the New Jersey Department (NJDEP) Bureau of Environmental Radiation: On 6/28/2023, NJDEP Bureau of Environmental Radiation (BER) was notified by its NRC Regional State Agreements Officer of an allegation made by a concerned citizen regarding a powder being sold by an online marketplace. The company address is in New Jersey. The citizen believed the powder contained Thorium-232 (Th-232). BER subsequently followed up with a site investigation and confirmed that Th-232 was present. The individual on-site stated that the powder had been mixed into paint, which was used to paint the walls in his basement and bathroom. The investigation is ongoing. On 7/8/2023, BER staff visited the seller's residence to perform an interview and contamination survey. The survey confirmed the presence of alpha and beta contamination in the residence. A sample of the powder was also collected and sent for gamma spectrometry analysis by a certified laboratory. Results of the analysis were received on 8/14/2023, and indicated concentrations of Th-232 as 14,800 pCi/g. On 8/15/2023, an estimate on the total activity present was made, and it was determined that this was a reportable event. New Jersey Event Report Number: Not yet assigned
