Experimental results show that electron just as affective as γ-ray has significant mutagenic effect on cells. In the range of the dose, the frequency of chromosomal aberrations on the root tip cells, there are singnificantly dose-effect. But the relationship between the dose and frequency of aberrations is close to straight line and redplication. An analysis from the type of chromosomal aberrations by electron also leads to different results, in which there are more bridges and rings by electron than by γ-ray. Therefore, electron possibly have stronger two hit aberrations, and the frequency of aberration increased in proporti on with the square of dose.
