NRC proposes changes to its rules on nuclear materials
In response to Executive Order 14300, “Ordering the Reform of the Nuclear Regulatory Commission,” the NRC is proposing sweeping changes to its rules governing the use of nuclear materials that are widely used in industry, medicine, and research. The changes would amend NRC regulations for the licensing of nuclear byproduct material, some source material, and some special nuclear material.
As published in the May 18 Federal Register, the NRC is seeking public comment on this proposed rule and draft interim guidance until July 2.

Gamma-ray spectra from the radioactive decay of 140Ba and 140La were observed by Ge(Li) spectroscopy. Gamma-ray energies were found to be consistent with literature values, but several of the observed gamma rays were found to have intensities differing significantly from those previously reported. Absolute intensities of prominent gamma rays emitted in the radioactive decay of 140Ba and 140La have been measured. The 12.8-day 140Ba activity was produced by 14.8-MeV neutron fission of 238U followed by radiochemical separation and purification.
