Estimation for Uranium and Thorium Isotopes Behavior in Various Iron Ore by α Spectrometry

Determination of uranium isotopes (234U, 238U) and natural uranium (U-nat) in water samples by alpha spectrometry

Background: Due to the potential public health effects of releases of uranium to the environment, isotopic determination and measurement of this radionuclide in environmental samples is very important. Achieving this goal, monitoring programs for this radionuclide seems necessary to be applied in many countries. Materials and Methods: The uranium was separated from the water samples using anion...

Plutonium, protactinium, uranium and thorium isotopes determination in environmental samples by SF ICP-MS

Alpha spectrometry is the most commonly used analytical tool for the determination of Pu, Am, Pa, U and Th long live radionuclides. Thermal ionization mass spectrometry (TIMS) and acceleration mass spectrometry (AMS) are also still considered as primary methods for the determination of their isotope ratios. Spectrometers with plasma ion sources now offer another efficient alternative method wit...
