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.

Thin high intensity alpha-particle sources were prepared for the NASA Surveyor Alpha Scattering Experiment. The alpha-active isotope used for this experiment was 242Cm prepared by neutron irradiation of 241Am in a reactor. After irradiation the curium was separated from americium, fission products, and aluminum by liquid-liquid extraction, redox precipitation, and extraction chromatography techniques. The sources were prepared by vacuum sublimation of the curium onto stainless-steel plates, followed by carbon coating from a carbon arc and encapsulation for installation into the Alpha Scattering Instrument.
