英文摘要	Radiation rays, especially gamma rays, are produced during nuclear fusion plasma discharge. To obtain the gamma rays around the Experimental Advanced Superconducting Tokamak (EAST) during nuclear fusion plasma discharges, Ar-based gamma ray detectors have been adopted in this article, and to fully monitor the gamma ray dose rates inside the EAST hall, three gamma ray detectors have been set at three selected radiation monitoring sites. Due to the long distances between the monitoring personal computer (PC) and each radiation monitoring site, the monitoring system based on the RS-485 differential communication mode has been designed and set up. With each plasma discharge, the gamma ray radiation field undoubtedly appears as a pulsed radiation field in the EAST hall. Based on the gamma ray dose rates obtained by the monitoring system, the pulsed radiation field of gamma ray dose rates has been carefully studied during one lower hybrid current drive (LHCD)-based plasma discharge. Finally, the exponential function model of the gamma ray dose rates during one plasma discharge in the EAST hall was well obtained and presented.
