摘要

与低水平被动伽马射线计数相比，中子活化分析通常不被用于环境放射性测量。德克萨斯州当地的背景样本被作为比较中子活化和被动计数研究的一部分。对于长期平衡的土壤样品，包括伽马射线自衰减、样本量和计数次数，探讨了每种方法的优缺点。

Comparison of neutron activation analysis and passive counting for environmental radioactivity measurements

Neutron activation analysis is not usually known used for environmental radioactivity measurements as compared to low-level passive gamma-ray counting. Texas local background samples were taken as part of a study to compare neutron activation versus passive counting. The benefits and drawbacks of each method are explored for soil samples which are in secular equilibrium, including gamma-ray self-attenuation, sample size and counting times.

期刊介绍： The Journal of Environmental Radioactivity provides a coherent international forum for publication of original research or review papers on any aspect of the occurrence of radioactivity in natural systems. Relevant subject areas range from applications of environmental radionuclides as mechanistic or timescale tracers of natural processes to assessments of the radioecological or radiological effects of ambient radioactivity. Papers deal with naturally occurring nuclides or with those created and released by man through nuclear weapons manufacture and testing, energy production, fuel-cycle technology, etc. Reports on radioactivity in the oceans, sediments, rivers, lakes, groundwaters, soils, atmosphere and all divisions of the biosphere are welcomed, but these should not simply be of a monitoring nature unless the data are particularly innovative.
