Rapid separation method for actinides in emergency soil samples

Rapid method for plutonium-241 determination in soil samples

A simple and rapid procedure for the determination of plutonium isotopes in the environment is presented. The procedure combines alpha spectrometry, solvent extraction and liquid scintillation measurements to ensure that both alpha- and beta-emitting isotopes are determined. Of five tested extractants, bis-(2-ethylhexyl) phosphoric acid was found to be the best choice. The procedure was applied...

An emergency radiobioassay method for 226Ra in human urine samples.

A new radioanalytical method was developed for rapid determination of (226)Ra in human urine samples. The method is based on organic removal and decolourisation of a urine sample by a polymeric (acrylic ester) solid phase sorbent material followed by extraction and preconcentration of (226)Ra in an organic solvent using a dispersive liquid-liquid microextraction technique. Radiometric measureme...

Rapid measurement of soil water by gravimetric method

A rapid method for estimating mercury in undigested biological samples.

Magos, L., and Cernik, A. A. (1969). Brit. J. industr. Med., 26, 144-149. A rapid method for estimating mercury in undigested biological samples. A method has been developed for estimating mercury in biological samples using an ultraviolet mercury detector, after liberating the mercury from the urine and other biological samples by a simple chemical method. The overall time for one estimation i...

Presenting a rapid method for detection of Bacillus cereus, Listeria monocytogenes and Campylobacter jejuni in food samples

Objective(s): Listeria monocytogens, Bacillus cereus and Campylobacter jejuni are three toxin producing bacteria over the world, especially in Iran, and it is essential to find a certain, rapid procedure to identify these microorganisms. In this research, these bacteria were simultaneously detected by multiplex PCR technique in foods. Materials and Methods: The primary approval of bacterial str...
