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.

Electron-photon cascade calculations have been carried out for zero-width beams of 1-GeV electrons normally incident on semi-infinite slabs of water and aluminum. The energy deposited as a function of depth and radius is presented and compared with experimental measurements. The overall agreement between the calculated and experimental results is quite good and is adequate for most shielding purposes.
