Abstract: Based on the source term analysis of ⁶⁰Co containing very low level radioactive soil waste which was temporarily stored in urban radioactive waste repositories in Sichuan Province, a landfill disposal plan was determined through research on radioactive waste disposal sites in Sichuan Province and a design of landfill units was put forward. According to the landfill disposal plan, this batch of very low level soil waste containing ⁶⁰Co was landfilled, and the radiation dose to the workers during the landfill process was estimated. After calculation, the total personal dose to the workers during this landfill operation is 103.07 μSv, that meets relevant dose control requirements.

Key words: ⁶⁰Co, very low level waste, soil waste, landfill disposal
