Behavior of Strontium-90 in Mugwort.

Search 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 ...

Interpretation of levels of strontium-90 in human bone.

Concentration of Strontium-90 at Selected Hot Spots in Japan

This study is dedicated to the environmental monitoring of radionuclides released in the course of the Fukushima nuclear accident. The activity concentrations of β(-)-emitting (90)Sr and β(-)/γ-emitting (134)Cs and (137)Cs from several hot spots in Japan were determined in soil and vegetation samples. The (90)Sr contamination levels of the samples were relatively low and did not exceed the Bq⋅g...

Simulating 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. ...

Strontium-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...
