| 1 | Design and development of a plastic scintillator based whole body β/γ contamination monitoring system显示文摘Plastic scintillation detectors based whole body β/γ contamination monitors are developed for use in radiation facilities.This microcontroller-based multi-detector system uses 13 plastic scintillator detectors,with minimized dead detection zones,monitoring the whole body,and conforming to the contamination limit prescribed by the regulatory authority.This system has the features for monitoring hands,feet,head,and faceβ/γusing contamination monitors and portal exit monitors.It can detect gamma sources at a dose rate of 10 n Gyh^(-1).The system is calibrated using b sources^(90)Sr/^(90)Y,^(204)Tl,and^(36)Cl,and the efficiency is found to be 29%,22%,and 18%,respectively.Theminimumdetectableβ/γcontaminationis0.15 Bqcm^(-2),which is significantly less than the minimum detection objectives on head,face,hands,and feet. | Vaishali M.Thakur Amit Jain P.Ashokkumar Rekha Anilkumar Pravin Sawant Probal Chaudhury L.M.Chaudhari | 2021 | Nuclear Science and Techniques2021，32，5： | 1 |
