NRC v. Texas: Supreme Court weighs challenge to NRC authority in spent fuel storage case
The State of Texas has not one but two ongoing federal court challenges to the Nuclear Regulatory Commission that could, if successful, turn decades of NRC regulations, precedent, and case law on its head.

The gamma-ray scattering technique has shown promise for the continuous measurement of atmospheric density from space vehicles. To understand and optimize the parameters of this technique, mathematical models have been derived and used to study design parameters such as gamma-ray source energy, source-to-detector separation, detector discriminator settings, and shield effectiveness. The predicted effects agree generally with the experimental results obtained in feasibility studies, and mathematical modeling promises to be an effective means for optimizing the design of the gamma-ray scattering technique for measuring atmospheric density.
