A fast gamma-ray source localization method for mobile robots

Appl Radiat Isot. 2022 Jul 9;188:110377. doi: 10.1016/j.apradiso.2022.110377. Online ahead of print.ABSTRACTA method for fast estimation of radioactive source parameters is presented. Full use was made of multiple continuous count values, combined with triangulation with four-point sampling method to solve high-dimensional optimization to obtain initialized estimates, which converge to maximum likelihood estimation using an improved hill-climbing algorithm. Cobalt-60 search experiments were conducted in the laboratory using a mobile robot carrying a NaI(TI) detector. Experimental results showed that the method can significantly improve the computational speed.PMID:35841851 | DOI:10.1016/j.apradiso.2022.110377
