| Zusammenfassung: | Rapid screening of super(90)Sr activity in water and milk samples using Cherenkov radiation was investigated. super(90)Sr/ super(90)Y Cherenkov radiation measurements of milk samples could be used for rapid screening of samples, which were contaminated with activities higher than 1.7 Bq L super(-1), without any pretreatment of the samples. It was indicated that super(90)Sr/ super(90)Y Cherenkov radiation measurements could be used for water samples with activities higher than 0.47 Bq L super(-1). The efficiencies of super(90)Sr/ super(90)Y Cherenkov measurements were 13.6% for milk and 48.9% for water samples. The results indicated that the time required for screening milk samples of 75 Bq L super(-1) super(90)Sr/ super(90)Y with more than 50% error was 100 min and samples with 125 Bq L super(-1) super(90)Sr/ super(90)Y was 30 min. |
