Invisible X-rays turn blue

A new reaction system can detect X-rays at the highest sensitivity ever recorded by using organic molecules. The system, developed by researchers at Nara Institute of Science and Technology (NAIST), Ikoma, Japan; and Centre National de la Recherche Scientfique (CNRS), Toulouse, France, involves the cycloreversion of terarylene, causing the molecule to switch reversibly between colorless and blue isoforms in the presence or absence of X-rays. With detection at safe doses, this reaction system is expected to detect even the faintest X-rays levels considered dangerous.
