Abstract. A rapid method for measuring Sr-90 activity in crop ashes is presented. Liquid scintillation counting, combined with ion exchange columns 4', 4"(5")-di-t-butylcyclohexane-18-crown-6, is used to determine the activity of Sr-90 in crops. The yields of chemical procedure are quantified using gravimetric analysis. The conventional method that uses ion-exchange resin with HDEHP could not completely remove all the bismuth when comparatively large lead and bismuth exist in the samples. This is overcome by the rapid method. The chemical yield of this method is about 60% and the MDA for Sr-90 is found to be 2.32 Bq/kg. The whole procedure together with using spectrum analysis to determine the activity only takes about one day, which is really a large improvement compared with the conventional method. A modified conventional method is also described here to verify the value of the rapid one. These two methods can meet different needs of daily monitoring and emergency situation.

“…Several rapid alpha and/or beta methods are described, all are based on liquid samples using a gas-filled proportional counter instead of LSC (Bari, 2011). Kabai et al describe a method for milk and liquid dairy products using LSC (Kabai, 2011).…”

“…Some methods were proposed to shorten the analysis time. Tait et al (1997) employed a solid phase extraction system and Kabai et al (2011) described a fast analytical method based on three steps, using a Sr-specific resin. An overview of available methods for determination of radio-strontium in milk, focusing on the parameter of the performing time, can be found in Brun et al (2003).…”
