- Alpha, Beta
- Betas from daughters Th-234 ((0.191 MeV) and Pa-234m (2.29 MeV)
- 4.5 x 109 years
- 0.25 inches glass and 0.4 inches plastic
- There also is gamma radiation associated with Uranium, but if chemical purification has removed the radium, the exposure rate will be quite low.
- Surface beta dose rate is 111 mrad/hr
- In general, uranyl nitrate or uranyl acetate are considered to be more chemically toxic as a heavy metal (lead or bismuth) than as a radiotoxic element and care should be taken to prevent ingestion by following good hygiene.
- Generally dosimeters are not required.
- Wear a lab coat and disposable gloves.
- Dusty, or vapor or aerosol-producing operations must be contained in fume hoods or glove boxes since deposition in the lungs is more hazardous.
