چکیده

Measurement of radon in water by g-ray spectrometry using a HPGe detector has been investigated to determine aquifer characteristics. The radon activity concentration is determined by taking the weighted average of the concentrations derived from g-ray lines associated with Pb and Bi decay. The role of accurate radon data to representatively sample aquifers was also investigated by studying a semi-cased borehole. A simplified physical model describing the change of radon concentration with the pumping time, reproduces the data and predicts the time for representative sampling of the aquifer. & 2008 IAEA.

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...

Calculation of beta absorbed fractions for iodine isotopes in ellipsoidal thyroid lobe

Background: The thyroid gland absorbs nearly all the iodine in the blood, independently of its isotopic composition. When a large enough activity of radioactive iodine like 131I, 132I, 133I is taken into the body, it can destroy the healthy thyroid gland cells as well as the cancer’s cells. In fact, as it is well known, some isotopes of iodine are used not only for acquiring thyroid image...
