A Radio‐Fluorogenic Organic Gel for Real‐Time, 3D Radiation Dosimetry

A radio-fluorogenic gel makes it possible to visualize the spatial intensity of “invisible” ionizing radiation. This is illustrated for the gamma-ray emission from a small seed of the radioactive 192Ir isotope of iridium. The underlying mechanism involves the conversion of a non-fluorescent molecule into a fluorescent form when incorporated into a radiation-initiated, growing chain of a bulk monomer.
