光释光测年中铀、钍、钾的NAA分析
Determination of U,Th and K for Optically Stimulated Luminescence Dating by NAA
【摘要】 光释光(OSL)测年法被广泛应用于我国北方的黄土古土壤序列及其记录的气候环境变化、古地震、古人类遗址和考古研究等方面的测年和年代学研究。对中子活化分析(NAA)用于光释光测年所涉及到的地质样品中的铀、钍、钾含量的测定方法进行了优化,建立了微型中子源反应堆(MNSR)中子活化分析准确测定黄土样品中的铀、钍、钾含量的流程,为光释光测年提供了可靠的基础数据。
【Abstract】 Optically stimulated luminescence dating techniques have been widely used in northern Loess ancient soil series and recorded climate environment change,ancient earthquake,the ancients site and archeology research.The determination of U,Th and K using neutron activation analysis(NAA) has been optimized for the samples related to OSL dating research.The procedure for determination of U,Th,K in loess have been fixed by using Miniature neutron source reactor.This procedure of NAA will provide a reliable data base for optically stimulated luminescence dating research.
