Survival of human lymphocytes after X-ray and ultraviolet irradiation was studied in individuals of various ages using a technique of cloning in soft agar. There was no effect of age on survival after ultraviolet irradiation but lymphocytes from elderly individuals were approximately twice as sensitive to X-radiation as lymphocytes from young individuals. The results are relevant to the possible importance of DNA damage and repair in cellular ageing.
使用软琼脂克隆技术，对不同年龄段个体的人类淋巴细胞在X射线和紫外线照射后的存活情况进行了研究。紫外线照射后，年龄对细胞存活没有影响，但老年个体的淋巴细胞对X射线的敏感性大约是年轻个体淋巴细胞的两倍。这些结果与DNA损伤和修复在细胞衰老中可能的重要性相关。
