【摘要】 用γ射线透射法进行了不同壁厚的输油管对γ射线衰减的模拟实验研究.实验装置由Cs-137γ源和NaI(TL)闪烁探测器组成.采用带有保温层的不同厚度的铁板,代替不同壁厚的输油管道,测量了有保温层的铁板厚度响应曲线,并与理论计算结果进行了比较.更多还原

【Abstract】 The Study of simulated experiment on decay of γ ray in petroleum pipeline of different thickness of pipeline wall is carried out with γ ray transmission method. Experimental Provision consists of 137Cs γ radiators and NaI (TL) scintillation detector. To substitute iron plate of different thickness with thermal insulating layer for petroleum pipeline of different thickness of pipeline wall, we have measured response curve of iron plate with thermal insulating layer, and compared with the result of theoretical account.更多还原
