On the capabilities of isotope dilution alpha spectrometry in the determination of plutonium concentration

Chemically selective polymer substrate based direct isotope dilution alpha spectrometry of Pu

“…The uncertainties at different steps can be minimized using an isotope dilution or standard addition with appropriate radiotracer coupled with a suitable radiometric technique [15][16][17][18][19]. Though multistep hybrid methods are highly precise and accurate, the time required for obtaining results is a bottleneck particularly for emergency preparedness as well as for risk assessment of contaminated areas resulting from nuclear weapon tests, nuclear accidents, and the discharge of nuclear waste.…”

Spectrophotometric Determination of Plutonium in Highly Radioactive Liquid Waste Using an Internal Standardization Technique with Neodymium(III)

“…Since the 1990s, the International Atomic Energy Agency (IAEA) has attached great importance to strict safeguarding for such radioactive waste from the standpoint of the non-proliferation of nuclear materials, and minor Pu in HRLW has been recognized as one of the important objects for nuclear inspection. For the determination of Pu in the HRLW, isotope dilution mass spectrometry (IDMS) [1][2][3][4][5][6] and alpha-ray spectrometry 7,8 have been applied to inspection analyses at TRP. In general, IDMS is a very well-established technique and is the most reliable analytical method for accountability measurements of nuclear materials in spent-fuel reprocessing plants.…”
