Improvement on the performance N-(3-methoxypropyl)acrylamide polymer-gel dosimeter by the addition of inorganic salt for application in radiotherapy dosimetry

The effect of lithium chloride (LiCl) on the dose–response performance of the N-(3-methoxypropyl)acrylamide polymer-gel dosimeter (NMPAGAT) was studied for 3-D dose measurements. The NMPAGAT-LiCl dosimeters were irradiated for various doses using a 6 MV medical linear accelerator. A 0.5 Tesla nuclear magnetic resonance (NMR) instrument was used to scan the signal development of the irradiated dosimeters in terms of the spin–spin relaxation rate …
