摘　　要：介绍新一代同位素75Se源的结构、特点、物理化学性能以及最新应用领域。较192 Ir和16 9Ybγ射线源 ,75Se半衰期长 ,对操作者安全 ,透照 5～ 4 0mm厚钢时影像质量高 ,非常适用于管道爬行器和野外作业 ,是一种用途广泛的新型γ射线源。The construction, character, physical and chemical property of a new generation isotope source 75 Se and its applications are introduced. Compared with 192 Ir and 169 Yb, its half life is longer and it is more safer to operator. Good image quality can be got when it is used to inspect the steel with thickness of 5～40mm. As a new generation source for γ radiographic inspection, 75 Se is adapted for pipeline crawler and is superior in on site inspection.
