Abstract |
The chromosome aberration yield for human lymphocytes exposed in vitro to various doses of (137) Cesium has been studied. Dicentric, total acentric, and excess acentric data were seen to follow a Poisson distribution. Calculated total hits demonstrated over-dispersion which could possibly be accounted for by a greater occurrence of single-hit phenomena being repaired than two-hit exchange processes. The resulting distribution generally contained an under-representation of cells with odd numbers of hits and an over-representation of zero- and even-hit classes as compared with Poisson predicted values. A possible use of scoring 'normal' cells for purposes of biological dosimetry is presented. |
