用超软X射线辐照在被辐照材料中产生短的限定长度的电子轨迹。这一特性在区分辐射对生物体作用的不同模式方面特别有意义。本文叙述了能量为1.5keV的铝K特征X射线的产生、吸收和剂量测定。用这些X射线对哺乳动物细胞进行定量实验是可能的，并且发现它们在体外灭活中国仓鼠V79细胞方面比γ射线有效得多。
Irradiation with ultrasoft X-rays produces electron tracks of short defined lengths in the irradiated material. This property is of particular interest in distinguishing between different models of radiation action on living organisms. The production, absorption and dosimetry of aluminium K characteristic X-rays of energy 1.5 keV are described. Quantitative experiments on mammalian cells with these X-rays are possible, and they were found to be considerably more effective than gamma-rays in inactivating Chinese hamster V79 cells in vitro.
