Human peripheral blood was exposed to various 60Co γ-ray with doses ranging from 0-7 Gy. The premature condensed chromosome (PCC) technique was used to study the yield of G1-PCC fragments. The direct visualization of chromosome aberrations in interphase has been examined. The frequency of chromosome breaks produced in G1-PCC of the lymphocytes was scored. The results was compared with the conventional cytogenetic assay. The yield of G1-PCC fragments immediately after exposure is fitted with the linear regression equation.
