Effect of lithium chloride inorganic salt on the performance of N-(Hydroxymethyl)acrylamide polymer-gel dosimeter in radiation therapy

The impact of lithium chloride inorganic salt (LiCl) on the response of radiated N-(Hydroxymethyl) acrylamide (NHMA) polymer gel dosimeters was presented in this article. The NHMA-LiCl polymer dosimeters were positioned in a cubic water-phantom and then irradiated by a linac to different dose ranging from 0 to 10 Gy. The response of gel to X-ray radiation was evaluated using NMR spin–spin relaxation rate (R2 = 1/T2). Linearity relationship of …
