Abstract

CARVALHO, Heloisa de Andrade. Use of Tradescantia to monitor the clastogenic effects of ionizing radiation. Radiol Bras [online]. 2005, vol.38, n.6, pp.459-462. ISSN 1678-7099.  https://doi.org/10.1590/S0100-39842005000600015.

The influence of chemical and physical agents (specially radiation) on the frequency of mutations has been widely studied by means of the analysis of changes observed in Tradescantia, a plant used as a bioindicator. The evaluation of these genetic changes may be performed both by detection of somatic mutations or chromosome abnormalities induced by mutagens that are present in the air, soil, or water. The results obtained from several studies support the use of Tradescantia for monitoring the effects of ionizing radiation. Studies of mutagenicity and chromosomal abnormalities may be carried out in future to compare the effects of other types of radiation, evaluation of the effects of the combined use of radiation and drugs or other chemical agents, and to monitor high risk environments.

Keywords : Radiobiology; Mutation; Tradescantia; Ionizing radiation.
