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.

Recent solutions to inverse problems are reviewed for the estimation of optical properties or the thickness of a medium, or the presence of a spatially distributed source or an obscured object. Time-independent and time-dependent applications are considered, and both closed-form (explicit) and iterative (implicit) methods of solution are described.
