摘要

用Ｓｉ（Ｌｉ）探测器实测了Ｎａ、Ｍｇ、Ｓ、Ｃｌ的特征Ｘ射线在有机膜中的相对衰减以及与Ｏ、Ｋ元素的特征Ｘ射线能量相当的Ｘ射线或轫致辐射在有机膜中的相对衰减，分别得出了它们衰减的数学描述，并把实验得到的不同能量的Ｘ射线在有机膜中的质量吸收系数与Ｂｅｒｋｅｌｅｙ的ＯＣＧ软件计算出的结果相比，相差都小于３０％．外延实验数据曲线得到这些特征Ｘ射线在有机膜中衰减到原来的千分之一时的作用范围，并讨论了低能重离了产生生物效应的可能机理。

Abstract

The characteristic X-rays of Na

Cl and O

which are considered as constituent elements of plant seeds

are measured with a St（Li） detector when penetrating several layers of Mylar or Capton films. The measured absorption coefficients for different energies are compared with the calculated ones based on the OCG program written by Berkeley group in 1989. The relative error is less than 30%. The range of the characteristic X-rays is estimated.
