  Guidelines for the safe use of radioactive materials ...

  As reliance on this technique grows, its use by those without experience in radiation safety will increase. Methods: Tissue obtained during radioguided SLN biopsies was examined for residual radioactivity. Specimens with a specific activity greater than the radiologic control level (RCL) of microCi/g were considered radioactive.

  If uranium is so radioactive, how is it mined?

  Answer (1 of 13): Uranium is NOT so radioactive. In fact there is essentially zero danger from touching uranium. The danger is the ingestion of Uranium which is overwhelmingly from its chemical toxicity. The most radioactive natural Uranium isotope is U235 with 700 million year half life. That...

  Guidance about radiation safety on mining operations

  All Australian uranium mining and mineral sands operations are required to contain all radioactive wastes, in mined out pits or in engineered tailings dams. Mineral sands operations are usually required to either bury the radioactive monazite tails in the base of worked out pits, or to dilute them with nonradioactive tails and place in the pits, or in dredge ponds, during backfilling.
