摘　　要：作为低中水平放射性废物的最终去向,近地表处置场的安全具有非常重要的意义。结合某处置场设计工程,分析近地表处置场关闭后放射性核素释放景象,并建立模型论证其对环境的影响。结果表明,近地表处置场关闭后,放射性核素迁移对公众剂量很小,满足国家标准对公众照射剂量约束值的要求。As the ultimate destination of low-level radioactive waste,the safety of near surface disposal facilities is of great significance.Based on the design project of a disposal facilities,analyze the radioactive nuclide release scene after the closure of a near surface disposal facilities,and establish a model to demonstrate its impact on the environment.The results indicate that after the closure of the near surface disposal facilities,the migration of radioactive nuclides has a very small impact on the public dose,meeting the requirements of the national standard for the constraint value of public exposuredose.
