【摘要】 通过对巴丹吉林沙漠表层砂进行选频释光特性测定的工作,建立起一套标准测定方法。测定地质样品的选频释光特性时应采取的步骤包括:1)抽样测定剂量响应曲线获得适当的辐照剂量值并确定响应波长;2)测定样品的释光分频接收光谱确定样品的释光光子波长分布;3)通过测定样品的剂量响应曲线来验证辐照剂量值的设定,使样品具有辐射剂量计的特性。更多还原

【Abstract】 Exampled by measuring the selected frequency luminescence characters of surface sand of the Badain Jaran Desert,a standard method was set up. The process of measuring the selected frequency luminescence characters includes three steps. 1) Confirming the radiation dose and characteristic wavelength by measuring the dose response curve. 2) Confirming the distribution of the luminescence photon wavelengths by measuring the received spectra of separated frequency. 3) Verification the setting of the radiation dose by measuring the dose response curve again.更多还原
