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...
متن کاملElevated in vivo strontium-90 from nuclear weapons test fallout among cancer decedents: a case-control study of deciduous teeth.
Risks to health from large-scale atmospheric nuclear weapons testing are still relatively unknown. A sample of 85,000 deciduous teeth collected from Americans born during the bomb-testing years assessed risk by in vivo measurement of residual strontium-90 (Sr-90) concentrations, using liquid scintillation spectrometry. The authors' analysis included 97 deciduous teeth from persons born between ...
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 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...
متن کاملConcentration 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...
