Portable device and method for radioactive element enrichment sampling
2014
The invention provides a portable device and method for radioactive element enrichment sampling. The device comprises a water pump and an enricher, wherein the water pump is used for drawing a water sample from water to be sampled and enabling the water sample to flow into the enricher; an absorber is arranged in the enricher, and the enricher is used for performing radioactive element enrichment sampling on an inflowed water sample by utilizing the absorber. Through the use of the device, the environmental water sample can be directly extracted, a radioactive isotope in a very low content in the environmental water sample is enriched, the radioactive isotope with enough activity is accumulated for achieving subsequent measuring sensitivity, and particularly the device is suitable for sampling and collecting a caesium isotope. The device replaces a traditional sampling method of transferring a big-volume water sample to a laboratory, and the device has the advantages that the size is small and exquisite, and the structure is compact, so that the device is convenient to carry and transport.
