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.

The emission probability of the 312-keV gamma ray from the decay of 27-day 233Pa has been measured. A 4π beta-gamma coincidence counting system was used to determine the 233Pa sample disintegration rates, and Ge(Li) spectrometers were used to measure the gamma-ray emission rates. The resulting value for the emission probability is Iγ (312 keV) = (38.6 ± 0.5) photon/100 decays. The relative intensities of the K x rays and gamma rays emitted in the decay of 233Pa were also measured.
