Abstract
Post-irradiation identification and dose estimation are required to assess the radiation-induced effects on living things in any nuclear emergency. In this study, radiation-induced morphological/cytological changes i.e., numb er of root formation and its length, shooting length, reduction in mitotic index, micronuclei formation and chromosomal aberrations in the root tip ce lls of gamma-irradiated onions at lower doses (50-2000 cGy) are reported. T he capabilities of this biological species to store the radiation-induced i nformation are also studied. (C) 2001 Elsevier Science Ltd. All rights rese rved.
