| Abstract: | Radiochemical analysis auto-system of90Sr in liquid effluent from nuclear facilities was developed by using solid phase extraction disk to absorb Sr, Geiger counter to measure the activity of90Sr, solenoid valves and programmable controllers and so on. The system realizes the automation of sampling, enrichment, purification and activity measurement. The analysis time is about 30 min and the detection limit is less than 1 Bq/L, which can meet the requirement of90Sr analysis in liquid effluent from nuclear facilities. |
