摘要
用^(241)Am-Be 中子源照射煤样,测量中子感生的瞬发γ射线能谱,由特征γ射线的强度来确定 C、H 含量。所得 C 的误差<2％,H 的误差<0.05％,此方法可用来快速检测煤质。
Coal samples are radiated by ^(241)Am-Be neutron source.The induced prompt gamma rays by neutron are measured.We determined the contents of carbon and hydrogen in coal samples by characteristic gamma rays.The uncertainty of carbon and hydrogen content is less than 2% and 0.05% respectively.The method can be applied to the deter- mination of carbon and hydrogen in coal.
