该试验方法包含大多数模型的氧浓度检测方法,包括使用14-MeV的中子活化和直接计数技术。本质上,同一检测系统可依据样品规格和可用的14-MeV中子注量率来计算被检测物的氧浓度,浓度范围包括10μg/g以下和500 mg/g以上。该试验方法可应用于固态及液态样品,前提是这些样品在辐射过程中保持规格、形状和宏 This test method includes oxygen concentration detection in most models, including neutron activation and direct counting using 14-MeV. Essentially, the same test system calculates the oxygen concentration of a test substance based on the sample specification and the available 14-MeV neutron fluence, in the range of 10 μg / g or less and 500 mg / g or more. The test method can be applied to solid and liquid samples, provided that these samples maintain the specifications, shape and macro during irradiation
