The following information was provided by … The following information was provided by the Florida Bureau of Radiation Control via email:</br>Unmonitored work was recently performed, resulting in an internal exposure to one of two construction workers. Neither worker was a trained qualified radiation worker so public exposure limits are applicable.</br>The two construction workers submitted urine bioassay samples 5 days after working in a room impacted with total and removable alpha and beta surface contamination. There is a history of work with uranium on (a different floor of the facility), and gamma spectroscopy analysis of the positive smear samples did indicate uranium radionuclides.</br>One of the two samples was positive for U-238, U-235, and U-234. An assessment of the resulting internal exposure was performed. If the uranium was lung retention Class Y, the resulting dose of 18,000 mrem committed dose equivalent (CDE) to the bone surface exceeds the applicable public CDE limit of 1,000 mrem. Since the lung retention class based on chemical form of uranium is not known for the uranium contamination, it is reasonable to assume that 1/3 of the inhaled uranium was Class Y (e.g. UO2 or U3O8), 1/3 Class W (e.g. UO3), and 1/3 Class D (e.g. uranyl salts). This still results in a CDE to the bone surface of 6,020 mrem, also exceeding the applicable public exposure limit. If the chemical form of the uranium present is Class W or Class D, there is exposure, but the results are less than applicable public exposure limits.</br>This is the initial report, more information to be added as provided by licensee.</br>Florida incident number: FL26-003icensee.
