Measurements of Strontium-90 in portuguese milk samples using liquid scintillation counting technique
The objective of this study is the implementation of a method combining extraction chromatography and liquid scintillation counting (LSC) technique to the determination of 90Sr in milk samples. The strontium separation is performed using the commercially available Sr-resin (Eichrom) and the beta counting is carried out using a liquid scintillation detector system (Tri-Carb 3170 TR/SL, Packard)....
متن کاملSearch for Strontium-90 in Deciduous Teeth*
Contamination maps do not exist ; at best, strontium measurements are carried out sporadically by individual research groups. Furthermore, strontium is not at all looked for in the foodstuffsdatabase, which is used to calculate the radiation exposure of the population through taking in contaminated food. But it is known that relevant amounts of radioactive strontium were found in the teeth and ...
متن کاملSimulating the Transfer of Strontium-90 from Soil to Leafy Vegetables by Using Strontium-88
The transfer, from soil to Chinese cabbage and spinach, of radioactive strontium-90 released as a result of accidents in nuclear power stations was studied using a stable isotope of strontium, namely nuclide strontium-88 (88Sr). The study led to an experimental model for assessing the hazard of radionuclide strontium-90 (90Sr) entering the food chain and for predicting the risk to food safety. ...
متن کاملA strontium-90 sequestrant for first-aid treatment of radiation emergency.
In this study, hydrophilic porous polymer beads with phosphonic acid groups (PGMA-EGDMA-TTA-MP) were synthesized, and assessed as a radioactive strontium-90 sequestrant for the treatment of the radiation emergency. Strontium ions were rapidly absorbed into the blood from the gastrointestinal (GI) tract after oral administration to rats, and distributed to the target organ, i.e., bones. Over 40%...
متن کاملStrontium-90 and intrauterine development in the rat.
It is well known that the developing mammalian embryo is sensitive to irradiation from external sources, causing developmental anomalies and lethal effects, and that this sensitivity can vary with stage of development (Hicks, 1953; Levy et al 1953; Fraser, Kalter, Walker & Fainstat, 1954; Russell & Russell, 1954; Warkany, 1954; Wilson, 1954; Rugh, 1963). Irradiation of the embryo prior to impla...
