AHA Report Says Over 40% of Rural Hospitals Have Negative Margins as Federal Policy Changes Loom

A radiotherapy source melted in a Spanish steel mill in 1998, and the mill’s own detectors missed it. Air filters in Switzerland, France and Italy caught the cesium first, setting off a hunt for its origin.

A plutonium-238 generator left on Nanda Devi in 1965 was never found, at the head of a watershed that feeds the Ganges. The records show a real loss, a 1978 scare and decades of testing with no documented release.

In a Dutch sham-controlled trial, 44% of patients given low-dose knee radiation improved, against 43% who heard only a recording of the treatment. A therapy in routine use across Europe now faces a hard question: what does the beam itself add?

Petitioners in 2015 and an executive order in 2026 both pushed the NRC to abandon the linear no-threshold model. A proposed rule would now drop ALARA, yet the low-dose end of the risk curve is still drawn the same way.

When Cosmos 954 broke apart over northern Canada in 1978, a satellite failure became a radioactive cleanup and a dispute over who should pay.

A small rise in heart rate during regadenoson stress carries prognostic information. Turning that signal into a treatment decision remains a separate question.

Motion correction can improve coronary CT interpretation. Proving that it also improves automated plaque measurements requires a different kind of validation.

Federal financing and a Medicare payment incentive support U.S. molybdenum-99 production. NorthStar’s earlier withdrawal shows why technical success is only part of the problem.
