Title: Effects of urban debris material on the extraction chromatographic separation of strontium: Part II: cement and concrete

The majority of radiochemical separation schemes available have been developed for environmental samples that are not necessarily representative of those found in an urban environment. However, it is much more likely that an incident involving a radiation dispersal device (RDD) would occur in an urban or metropolitan area. It is unclear if the currently available separation schemes would be effective in such an event. It is therefore important to determine if the current schemes would be adequate, or to find efficient and accurate ways to separate radiological material from urban debris. One important radiological material that could be used in an RDD is 90Sr. Part I of this work investigated the effects steel had on strontium separations, while this work investigates cement and concrete. This research demonstrates that the individual elements present in a cement and concrete sample matrix can give rise to significant interferences with extraction chromatographic separations. In conclusion, solutions of the constituents mixed in representative ratios; however, show fewer problems
