Abstract: Abstract This investigation was performed to evaluate the influence of the static magnetic field (SMF) on chromosomes in Vicia faba cultivated in soil from high background natural activity. Fourteen soil samples were collected from Ramsar area, in north of Iran, which the annual radiation absorbed dose from background radiation is substantially higher than the 20 mSv/year. The specific activity of the radionuclides of 232Th, 236Ra, and 40K was measured using gamma spectrometry. The collected soil samples were then divided into 2 separate groups including HR (high natural radioactivity) and LR (low natural radioactivity). The cultivated Vicia faba in both groups were continuously exposed to SMF of 15 mT for 8 days, each 8 h/day starting from 2nd day. The chromosomal aberrations were counted in both groups with and without SMF from root of samples using chromosomal aberration method. The results showed a significant difference between treated and control plants. Chromosomal aberrations including bridge, fragments, and lagging chromosomes in prophase, metaphase, anaphase, and telophase enhanced significantly in treated groups compared with controls.
