Determination of Activity Concentration of Radioactive Waste Bags With Portable Dosimeter

For the determination of activity concentration of radioactive waste bags，the air absorbed dose monitoring with portable dosimeter was studied to determinate the specific activity of waste bag. The calculation and experiment got a consistent result on the study of the soil waste bag’s air absorbed dose contained ¹³⁷Cs. Taking into account some special questions and uncertainty in measurement, to determinate the specific activity of waste bag by monitoring its air absorbed dose is a reasonable way.
