土壤中氚化水浓度估算

摘要

Factors influencing HTO concentration in soil was analyzed ,and a method to estimate the concen-tration ratio between soil and air was resulted ,using the doses from chronic atmospheric releases of tritium (DCART) model developed by Lawrence Livermore National Laboratory (LLNL) .It indicates that the ratio will be influenced by absolute humidity ,soil water content and soil water recharge .%采用氚长期释放模式 DCART 对土壤中 HTO 浓度的影响因素进行分析，给出土壤与空气中 HTO 浓度比值的估算方法。结果表明，土壤与空气中 HTO 浓度的比值受空气绝对湿度、土壤含水量和补水量的影响，空气绝对湿度、土壤含水量与比值成正比，而补水量与比值成反比。
