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 ...

Strontium-90 concentration measurements in human bones and teeth in Greece.

Strontium-90 concentration was measured in human bones and teeth collected in Greece during the period 1992-1996. One hundred and five bone samples, mainly cancellous bone, and 108 samples, taken from a total of 896 individual teeth were processed. Samples were classified according to the age and sex of the donors. Samples were chemically pre-treated according to a specially devised method to e...

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...

Fallout, A Study of Superbombs, Strontium 90, and Survival

ness of a volume that attempts to construct too many bridges to too many of these interesting sites of investigation. The first section is concerned with melanin and is well done, especially the chapter by J. I. Harris on the chemistry of MSH, which is really an abbreviated primer on peptide "amino-acid sequence analysis." Brunet's chapter on melanogenesis is interesting and contains, in a note...
