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

Abstract: 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.

“…The potential of RFGs for determination of spatial dose distributions has been previously demonstrated [ 27 , 28 ], and the use of planar laser-induced fluorescence (PLIF) has been suggested and demonstrated to yield high-resolution images [ 29 , 30 ]. Independent investigators have recognized PLIF as a valid method, and are currently developing a reader system [ 31 ].…”

“…This is further complicated by the extremely rapid (~1/ r 2 ) decrease in dose with distance from a seed. We devised a simple system for monitoring in situ the fluorescence of an RFG gel on introduction of a seed of 192 Ir [30]. This set-up is shown in Figure 14.…”

“…Figure 15 shows images of the cell and catheter taken before insertion of the seed in room lighting and after a residence time of 3 min. Images were in fact taken while the seed was still present at intervals of 10 s and a time-lapse movie has been produced that illustrates the gradual increase in the fluorescence with time [30]. Of potential interest is that images could also be made after retraction of the catheter and relaxation of the surrounding gel.…”
