A rapid separation method for determination of promethium-147 and samarium-151 in environmental samples with high performance liquid chromatography

Five-Column Chromatography Separation for Simultaneous Determination of Hard-to-Detect Radionuclides in Water and Swipe Samples

“…1,2 Therefore, rapid and accurate determination of these radionuclides in various sample matrixes, including water, swipe, food, soil, and urine samples, etc., is often required for the purposes of environmental monitoring, workplace radiohazard characterization, and dosimetry assessment, as well as for nuclear forensic reasons. 3−10 Although a large number of procedures for actinide, 3−6,11 strontium, 7,8,12,13 promethium, 9,14 and iron 10,15−17 radioisotopes in environmental and biological samples have been developed, many of them are very time-consuming/tedious to operate and cover only few radionuclides of interest. In cases that multiple radionuclides in the same sample are required for analysis, simultaneous or sequential analytical procedures, using state-of-art stacked column chromatographic separation techniques, 18,19 would facilitate high sample analysis efficiency and cost-effectiveness.…”

“…In response to a nuclear emergency, there is an increasing need to develop simpler, faster, and high analysis throughput radioanalytical methods, particularly for hard-to-detect radionuclides (with no γ emission) that are impossible or difficult to identify with field instrumentation. Actinide isotopes, radiostrontium, 147 Pm, and 55 Fe are among the most important hard-to-detect radionuclides, due to their high radiotoxicities and abundant activation/fission productions during the operation of nuclear power reactors. , Therefore, rapid and accurate determination of these radionuclides in various sample matrixes, including water, swipe, food, soil, and urine samples, etc., is often required for the purposes of environmental monitoring, workplace radiohazard characterization, and dosimetry assessment, as well as for nuclear forensic reasons. − …”
