Concentrations of natural radionuclides in imported zirconium minerals

Assessment of radionuclides in imported foodstuffs in Iran

Background: Knowledge of radioactivity levels in human diet is of particular concern for the estimation of possible radiological hazards to human health. However, very few surveys of radioactivity in food have been conducted in Iran therefore the baseline values of the natural radionuclides concentration (40K, 226Ra and 232Th), and man made radionuclide, 137Cs, were determined in twenty six...

Natural Radionuclides in Seafood

Natural radioactivity concentration in raw materials used for manufacturing refractory products

Background: Some Particular areas contain natural radionuclide at levels much higher than those usually present in earth's crust. The radiological impact of the use of zirconium ore in zirconium industry is due to internal exposure of the lung by alpha particles and external exposure of the body by the gamma rays. The result of gamma spectrometry measurement of the concentrations of th...

Natural Minerals and Cancer

Various minerals have been reported which are directly linked to our health and cancer development in body. The immune system (immunoglobulin’s, cell mediated immunity, phagocytosis complement, lysosomes, interferon, metabolic function, hormones, metabolic and respiratory alkalosis) is the natural mechanism which defends against cancer. Minerals like zinc, selenium, magnesium, vanadium, and ger...
