α辐射效率K值的确定方法的探索
Comments on the assessment of α-efficiency K Value
【摘要】 本文认为样品的天然ESR信号强度I0和在剂量饱和时的ESR信号强度Imax之比可以反映K值的大小。用几个经铀系测年对比过的文石质珊瑚样品求出了确定K值的方程。用此方程确定K值可以提高ESR测年的精度。
【Abstract】 It was found that K value can be reflected by the ratio of natural ESR signal intensity I0 to the maximum ESR signal intensity 1mai at dose saturation. An equation of assessment of K. value, derived from several samples of aragonitic corals compared with U-series dating, was obtained. The precision of ESR datimg can be improved using the equation.
