Radon Determination by Activated Charcoal Adsorption and Liquid Scintillation Measurement
A passive diffusion method for the determination of radon concentration has been optimised and calibrated. The device consists of a scintillation vial containing activated charcoal, a diffusion barrier and a desiccant agent. The response to diverse atmospheric humidity and variable exposure intervals was studied. The result is a detector independent of atmospheric humidity till 7 days of exposu...
متن کاملMeasurement 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 کاملTritium Determination in Danube River Water in Serbia by Liquid Scintillation Counter
Tritium activity concentration in Danube river water in Serbia has been determinate using a liquid scintillation counter Quantulus 1220. During December 2010, water samples were taken along the entire course of Danube through Serbia, from HungarianSerbian to Romanian-Serbian border. This investigation is very important because of the nearness of nuclear reactor Paks in Hungary. Sample preparati...
متن کاملOptimization Method to Determine Gross Alpha-Beta in Water Samples Using Liquid Scintillation Counter
Liquid scintillation counting (LSC) is an adequate nuclear technique to determine radioactivity levels, as verified by this study for the determination of the gross alpha and beta activities of aqueous samples because of its simplicity and low associated cost comparison with other techniques. This paper discusses a new approach to the monitoring of gross alpha and gross beta activities in water...
متن کاملmultiwavelength pectrophotometric determination of stability constants of 4-(2– thiazolylazo) resorcinol (tar) with la3+, y3+ and th4+ in organic-water mixed solvents by chemometrics method & simultaneous spectrophotometric determination of lead, copper and nickel using xylenol orange by partial least squares calibration method
تشکیل کمپلکس های tarبا یون های لانتانیم, ایتریم و توریم در دمای 25 درجه، قدرت یونی ثابت 0.1 مولار و در ph ثابت در مخلوط حلال های اتانول – آب و استونیتریل – آب با استفاده از روش های اسپکتروفوتومتری مورد بحث و بررسی قرار گرفت. داده های اسپکتروفوتومتری با استفاده از نرم افزار squad پردازش شدند تا ثابت های تشکیل کمپلکس اندیکاتور – فلز را محاسبه کند. نتایج نشان می دهد که درصد حلال آلی در مخلوط حلال ...
