Radioanalytical methods for determination of alpha emitters in the environment

An alternative method for chronometric determinations involving curium

“…Simultaneous measurement of plutonium and trans-plutonium isotopes is necessary for applications ranging from environmental monitoring and radioactive waste management, [1][2][3][4][5][6] to nuclear forensics and nuclear safeguards, [7][8][9][10] to bioassay, [11][12][13] and basic nuclear physics research. [14][15][16][17] While traditional radiometric methods using yield tracers provide quantitative isotopic information, they typically require labor intensive separations that can reduce overall sample throughput for routine analyses.…”

Alpha Spectrometric Determination of Trace Level of 239-240Pu and 238Pu Uranium Compounds and Solutions

“…Of all the transuranium elements, plutonium has been studied most extensively and numerous procedures have been reported for its determination [1][2][3][4][5][6][7][8][9], Current techniques for the determination of plutonium trace level are mainly radiochemical methods (a-spectrometry, y spectrometry, liquid scintillation counting) carried out after chemical preparation of the samples. Interest has also tumed to various mass spectrometry techniques (ICP-MS [10,11], TIMS [12,13]), but those methods are not really adapted for a matrix where uranium is the principal constituent because of isobaric interfering effects.…”
