MICRODOSIMETRY..AND THE THEORY OF STRAGGLING. Theoretical developments in microdosimetry (the determination of the spatial distribution of energy deposition on a microscopic scale) are described. It is pointed out that microdosimetric theory is equivalent to LET theory plus straggling theory. The influence of each of the different random factors (varying LET, varying track length, varying numbe...
