摘要：作為低中水平放射性廢物的最終去向，近地表處置場的安全具有非常重要的意義。結(jié)合某處置場設(shè)計(jì)工程，分析近地表處置場關(guān)閉后放射性核素釋放景象，并建立模型論證其對環(huán)境的影響。結(jié)果表明，近地表處置場關(guān)閉后，放射性核素遷移對公眾劑量很小，滿足國家標(biāo)準(zhǔn)對公眾照射劑量約束值的要求。

Abstract： 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 exposure dose.

Keywords： radioactive waste; disposal; releasing scenario; environment impact
