The simple answer is, it depends on the enrichment.

At lower enrichments the chemical toxicity dominates the concern; at higher enrichments the radiological toxicity dominates the concerns.

DOE's standard DOE-STD-1136-2009, "Guide of Good Practices for Occupational Radiological Protection in Uranium Facilities" should help you with your questions. The document on DOE's technical standards website, which should be freely available.

Good Day RADSAFE!



I am interested in anyone's experiences regarding the following questions.




How much uranium powder is cause for concern regarding intake at your facility?


When working with uranium powders, at what amount do you consider the necessity to provide intake prevention controls (isolation, face shields, etc.)?



At what level of bioassay response do you consider a dose evaluation necessary?


Thank You!
