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...

متن کاملAlpha-recoil thorium-234: dissolution into water and the uranium-234/uranium-238 disequilibrium in nature.
The rate of ejection of alpha-recoil thorium-234 into solution from the surface of zircon sand gives an alpha-recoil range of 550 angstroms. The alpha-recoil thorium-234 atoms ejected into the groundwater may supply excess uranium-234. In pelagic sediments, ejected alpha-recoil thorium-234 may contribute to the supply of mobile uranium-234 in the sedimentary column.
متن کاملexploring motivation and english test preparation strategies of iranian pre-university candidates during and at the end of test preparation period for konkur examination
the current study aimed at investigating the relationship between motivation and test preparation strategies (tpss) used by iranian pre-university students in their preparation period for the university entrance exam (uee). due to the importance of uee in iran, this study also attempted to show its impact on these two important variables. to this end, 100 pre-university students in an iranian p...
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...
