The Radioactive Isotopes

Removal of cesium through adsorption from aqueous solutions: a systematic review

Cesium radioactive isotopes (134Cs and 137Cs) are dangerous to human health due to their long half-life and high solubility in water. Nuclear experiments, wars, and nuclear plant accidents have been the main sources of Cs release into the environment. In recent years, several methods have been introduced for the elimination of Cs radioactive isotopes from contaminated wate...

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...

Successful Experiments On Utilization Of High-Activity Nuclear Waste In The Process Of Transmutation In Growing Associations Of Microbiological Cultures

The problem of utilization of high-activity waste by effect of nuclear transmutation in growing associations of microbiological cultures was studied. For the first time we have observed utilization of several kinds of highly active isotopes in the volume of distilled water extracted from the first contour of water-water atomic reactor convert to non-radioactive nuclei. 1. The model and the foun...

The Light Curve in Supernova Modeled by a Continuous Radioactive Decay of 56

The UVOIR bolometric light curves are usually modeled by the radioactive decay. In order to model more precisely the absolute/apparent magnitude versus time relationship the continuous production of radioactive isotopes is introduced. A differential equation of the first order with separable variables is solved.
