Chemical contamination of seafood has become a global health concern. Carp fish is one of the most widely consumed globally, and several studies have been conducted on the contamination of carp fish with radioisotopes. In the current study, a meta-analysis and probabilistic exposure assessment regarding the Potassium-40 (40K), Polonium-210 (210Po ...

Estimation of Exchangeable Water and Potassium by Radioisotope Dilution in Children
Archives of Pediatrics & Adolescent Medicine, 1957Most measurements of the total body water in man using dilution techniques have been made using antipyrine or deuterium oxide (D 2 O) as tracers. In adult subjects, Schloerb and co-workers, using D 2 O, obtained mean values of 61.8% and 51.9% of the body weight in male and female subjects, respectively.

Science, 1981
An average age of 9.41 million years was obtained from radioisotope (potassium-argon) age determinations of three glass concentrates of a tuff from the upper part of the marine Rionegrense at Punta Cracker in Golfo Nuevo, Argentina. This age correlates with the Tortonian marine stage of Europe and the Chasicoan Land Mammal Age of South America.

Mikrochimica Acta, 1971
Extraction of scandium and calcium radioactivities with 1% HDEHP in benzene from nitric acid solution was investigated. The effect of potassium titanium oxalate concentration on the extraction from 1.5M nitric acid was studied. From the data obtained, two procedures based on batch solvent extraction and extraction chromatography were developed for ...

Advances in X-ray Analysis, 1970
AbstractAn x-ray spectrometer with experimental results is herewith described using a radiosotope source Fe55 having a halflife of 2.6 years. As a result of the disintegration, the managanese x-rays are capable of exciting fluorescent x-rays of such elements as sulfur, chlorine, potassium, calcium, scandium and titanium in aqueous solutions.
