Measurement of Strontium-90 in the Persian Gulf Fish by Extraction Chromatography with Sr-resin and Liquid Scintillation Counter
Background: Despite its beneficial effects on human life, the nuclear industry has its own risks. Strontium 90 (90Sr) is one of the most dangerous radionuclides produced by the uranium 235 fission, and replaces the bone calcium in the human body, which causes cancer. Ensuring the safety of nuclear facilities to protect employees, people and the environment is among the main goals of nuclear saf...
متن کاملAntioxidant agents in raw materials and processed foods.
Many food raw materials contain natural antioxidants which exert control of oxidative processes in the living cells. Among antioxidative agents are found enzymes such as superoxide dismutase, glutathione peroxidase and glucose oxidase-catalase. Among naturally occurring non-enzymic antioxidants are carotenoids, especially astaxanthin (e.g. in fish), tocopherols in oils and other phenolic compou...
متن کاملThe Scintillation Counter
The development of detectors for both counting and measuring the energy of particles and photons has played an important role in the evolution of nuclear physics. In this experiment, you will be introduced to one such detector the scintillation counter which is particularly suitable for detecting γ-ray photons. You will use it to observe the energy spectrum of γ-rays from several nuclei and stu...
متن کاملDetermination of chondroitin sulfate in raw materials by liquid chromatography.
A rapid method for the determination of chondroitin sulfate in raw materials was developed. The samples were finely powdered, dissolved in water, and injected directly into the liquid chromatograph. The method used a C18 column, a wavelength of 195 nm, and a mobile phase containing octane sulfonic acid. The method gave results that were slightly different from those generated by atitrimetric me...
متن کاملEditorial: Biogenic amines in foods
Biogenic amines (BA) are nitrogenous compounds of low molecular weight and are essential at low concentrations for natural metabolic and physiological functions in animals, plants, and microorganisms. Histamine, putrescine, cadaverine, tyramine, tryptamine, 2-phenylethylamine, spermine and spermidine are the most important BA in foods in which they are mainly produced by microbial decarboxylati...
