Micronucleus induction by low doses of X-rays in Vicia faba root tips [PDF]

, 1987
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.
