【摘要】 介绍一种新的热释光材料CaSO₄:Na,Dy 的制备方法和发光曲线。它的低、高温峰面积比可用于估算β照射的发生时间,在存放温度为10℃时又可估算三个月以内的事故受照事件的发生时间。更多还原

【Abstract】 The preparation method and TL glow curve of a new TL materials namely CaSO4:Na, Dy were described. The area ratio of low and high temperature glow peaks has been used to estimate the elapsed time after β irradiation. A good estimate of elapsed time after an accidental exposure within 3 months can be made for a dosimeter stored at 10℃.更多还原
