Abstract
Low levels of X-ray exposure of mouse palatal epithelial cell cultures resulted in increased numbers of chromosomal aberrations. At the lowest level used (IR), aberrations occurred of the type produced by two breaks such as chromatid exchanges, dicentrics, and metacentrics.
摘要
对小鼠腭上皮细胞培养物进行低水平的X射线照射会导致染色体畸变数量增加。在所用的最低水平（IR）下，出现了由两次断裂产生的畸变类型，如染色单体交换、双着丝粒染色体和中着丝粒染色体。
