This viewgraph presentation reviews some of the techniques used to analyze the damage done to chromosome from ion radiation . Fluorescence in situ hybridization ( FISH ) , mFISH , mBAND , telomere and centromereprobes have been used to study chromosome aberrations induced in human cells exposed to low - and high - LET radiation in vitro . There is some comparison of the different results from the various techniques . The results of the study are summarized .
