摘要

随着核聚变能源的不断发展，人们有理由担心氚化水（HTO）羽流可能释放的污染，以及大气中氚化氢气（HT）释放到附近土壤中的氧化。我们建立在过去的研究，通过检查氧化率HT到HTO在两个地点代表干燥和潮湿的土壤。我们还研究了日变化，以更好地限制微生物高温氧化和随后沉积到土壤中的速率。我们估计了氧化高温产生的高温烟羽的潜在影响。预计这一方法框架将有助于确定由于氢氧化氢排放而造成的氢氧化氢对健康和环境的潜在影响。

Conversion of hydrogen gas to water in soil: Implications to fusion contributions

With the continuing development of fusion energy, it is reasonable to be concerned about contamination from the potential release of tritiated water (HTO) plumes, as well as the oxidation of atmospheric tritiated hydrogen gas (HT) releases in nearby soils. We build on past studies by examining oxidation rates of HT to HTO at two sites representing dry and moist soil. We also examine diurnal changes to better constrain rates of microbial HT oxidation and subsequent deposition into soils. We estimate the potential effects of an HTO plume resulting from an oxidation HT. This methodology framework is expected to be useful in the determination of potential health and environmental impacts from HTO as a result of HT releases.

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.
