New type of imager could help spot smuggled nuclear materials
May. 19, 2021 , 2:00 PM
Much as a smoke detector gives only a vague idea of where a fire is, current methods to detect smuggled nuclear materials are slow and imprecise. But a new technique that images nuclear materials based on the neutrons and gamma rays they shed can locate these dangers in record time, scientists report.
“It’s an elegant method,” says Alexander Glaser, a physicist at Princeton University who works on nuclear weapons verification and was not involved with the new study. If it proves itself in real-world scenarios, he says, the new approach could strengthen border security and help map radioactive contamination at disaster sites like Chernobyl and Fukushima.

Ten years ago, three nuclear reactors melted down at the Fukushima Daiichi power plant in Japan, producing the worst nuclear accident since the 1986 Chernobyl disaster.The disaster, caused by an earthquake-triggered tsunami, pushed Japan and a few other countries to rethink their use of nuclear energy. But elsewhere, it didn’t spur major changes. Instead, experts say, climate change could force a major reckoning with how the world uses nuclear power.
Ten years ago, three nuclear reactors melted down at the Fukushima Daiichi power plant in Japan, producing the worst nuclear accident since the 1986 Chernobyl disaster. Hundreds of thousands of residents within eighteen miles of the power plant were forced to evacuate. Most haven’t returned, even though the government has said most areas are safe.
