摘要

本文以水成沉积物为研究对象

在实验室常用辐照剂量率1×10–1–1×102 Gy/min范围内

选择不同的剂量率对同种样品进行辐照

观察不同剂量率辐照下Al心ESR信号的剂量响应曲线特征。实验结果表明

不同人工辐照剂量率对水成沉积物样品的剂量响应特征没有影响

现有的人工辐照技术能够满足我们的实验要求。

Abstract

ESR dating samples need be irradiated to obtain dose response curve and the equivalent dose.The artificial dose rate is about 1×10–1–1×102 Gy/min

whereas the natural dose rate is about 3 Gy/ka.Therefore

one must be sure whether the much higher artificial dose rate is suitable for the ESR dating study.In this paper

we use different artificial dose rate to irradiate the same fluvial sample and measure the quartz Al centre ESR signal under the same conditions.The dose response curves are compared

in an attempt to gain a preliminary knowledge on that problem and build a good foundation for our ESR dating studies on fluvial samples.
