The micronuclei were identified according to the following criteria: micronucleus is distinctly separated from the parental nuclei; size of micronucleus is smaller than one-third the size of the main nuclei; and if there were more than two micronuclei present in a cell, the micronuclei were not counted.
A higher count of micronuclei is thus a barometer of the risk.
