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.
