【Abstract】 The At-211-tellurium colloid was used to induce chromosomal arerration in domestic pig lymphocytes cultured in vitro, to make the straight-line of cose-response, He legression lymilysis was then done. By doing the significance test of relational coefficient, it is proved that the straight-line of the dose-response is significant, The iesult shows that among the cell damages by alpha-radiation produced from the At-2ll-tellurium colloid, the damage of chromatin is most important and the efficiency of damage is very high.更多还原
