摘　　要：The physicochemical properties of soil from one disposal factory of low-radioactive waste are measured.The soil was dried in the air for 30 days,and screened.Following the solid-liquid ratio for 1∶5,the soil is counterpoised after 24 hours,then testing the pH,redox potential(Eh) and conductivity.The result shows that the pH of soil ranged from 5～7,it belonging to the middle-acid soil.The Eh shows that the oxidability of the soil is low.The conductivity is lower than 60μS/cm,so the conduction is very low.All of the references,including pH,Eh and conductivity,are showed different properties according to the depth of the soil.it is concluded that results of the soil’s physicochemical properties,are able to provide the references for the nuclide migration experiments.The physicochemical properties of soil from one disposal factory of low - radioactive waste are measured. The soil was dried in the air for 30 days, and screened. Following the solid - hquid ratio for 1 ： 5, the soil is counterpoised after 24 hours,then testing the pH,redox potential （Eh） and conductivity. The result shows that the pH of soil ranged from 5 -7 ,it belonging to the mid- dle - acid soil. The Eh shows that the oxidability of the soil is low. The conductivity is lower than 60μS/cm, so the conduction is very low. All of the references, including pH, Eh and conductivity, are showed different properties according to the depth of the soil. it is concluded that results of the soil＇s physicochemical properties, are able to provide the references for the nuclide migration experiments.
