title: Micronucleus induction by low doses of X-rays in Vicia faba root tips.
abstract: Studies on the micronucleus test in Vicia faba root tips (VM test) were carried out in order to estimate the effects at low doses of X-rays (1, 2, 4, 8 and 12 R). The control value of micronucleus frequency is about 0.44/1000 cells. The dose where the micronucleus frequency is twice that of the control was estimated at 1.384 R. There was a linear kinetic dose response for the low-dose range studied here.
