"Radiation safety is too important to be wasted on studies that cannot deliver answers. Science should chase questions that can be realistically answered & offer solutions to reduce risks that can actually save lives," write Adam Stein & Peter James
No, the United States does not need a costly national cancer study near nuclear reactors
Routine reactor emissions pose no meaningful health risk to the US workers and population, a health physicist and a nuclear engineer argue.

In nuclear safety, we spend too much time chasing statistical ghosts—deploying studies that cannot resolve risk instead of governing the risks that actually matter.
Today, @thebulletin.org published my article with PJ Seel on this exact problem.

In many ways, 2025 resembled Back to the Future, and not only because Donald Trump returned to the White House.
When it reconvenes in January, let’s hope the US administration comes back to the present and sets about a new start in nuclear arms control and diplomacy.

Policy leaves a track record. We can examine what officials promised compared to the outcome of their decisions. When we do, we see the only policy that has ever worked to restrain North Korea’s nuclear program has been engagement & diplomacy, not pressure & threats. thebulletin.org/2025/12/four...
