Microdosimetry measurements give information about the energy imparted to a volume of given size. With the most frequent method only data for object sizes above 0.2 micrograms are obtainable. Although restricted to the dose mean values, the variance technique can, however, be applied to objects sizes an order of magnitude less. In this report some limiting parameters for this technique are discussed and results down to about 20 nm in a 60Co gamma-ray beam are reported. the resulting data exceed earlier reported values at objects size below 0.1 microgram, but are in good agreement for larger object sizes.
微剂量学测量可提供有关赋予给定尺寸体积的能量的信息。采用最常用的方法,只能获得尺寸大于0.2微克的物体的数据。虽然方差技术仅限于剂量平均值,但它可应用于小一个数量级的物体尺寸。在本报告中,讨论了该技术的一些极限参数,并报告了在60Coγ射线束中低至约20纳米的测量结果。对于尺寸小于0.1微克的物体,所得数据超过了先前报告的值,但对于较大尺寸的物体,数据吻合良好。
