An external radiation monitoring station was taken out by shelling and fire near the Zaporizhzhia nuclear plant in Ukraine the last week of June.

This brings the total to four of the plant’s 14 radiation monitoring sites that are out of commission, further reducing the effectiveness of its off-site capability to detect and measure any radioactive release during an emergency, said IAEA director general Rafael Mariano Grossi.

Particle accelerators have evolved from exotic machines probing hadron interactions to understand the fundamentals of our world to widely used instruments in research and for medical and industrial use. For research purposes, high-power machines are employed, often producing secondary particle beams through primary beam interaction with a target material involving many meters of shielding. The charged beam interacts with the surrounding structures, producing both prompt radiation and secondary radiation from activated materials. After beam termination, some parts of the facility remain radioactive and potentially can become radiation hazards over time. Radiation protection for accelerator facilities involves a range of actions for operation within safe boundaries (an accelerator safety envelope). Each facility establishes fundamental safety principles, requirements, and measures to control radiation exposure to people and the release of radioactive material in the environment.

The 11th installment of the ANS Young Members Group's webinar series "Spotlight on National Labs" featured the Nevada National Security Site and went live on August 26. The event, moderated by YMG chair Matthew Jasica, featured 11 speakers from the NNSS describing the various programs under the agency. Kelsey Amundson, who co-organized the webinar, said, “The diversity of the work performed at the NNSS is quite extensive, and the webinar was a great way to show the nuclear community how much work is done at the [organization].”

A recording of the program is available online.
