Radioactive contamination from medical uses and recent regulatory activity in the U.S.A.

Recent publications relating to environmental radioactive contamination from medical uses are described. It appears that the unprecented growth of medical uses of radionuclide continues in the United States; hospital effluents are not a measurement problem; and the regulatory climate is uncertain. The major need, appears to be in the reduction or control of medical radiation exposure to the patient from diagnosis and therapy.
