Standard stratigraphic practice, however, requires a more significant, globall...
A tooth enamel electron spin resonance (ESR) dosimetry study was carried out with the purpose of obtaining the individual absorbed radiation doses of population from settlements in the Semipalatinsk region of Kazakhstan, which was exposed to radioactive fallout traces from nuclear explosions in the Semipalatinsk Nuclear Test Site and Lop Nor test base, China.

Activity concentrations of Cs, Sr and total beta varied seasonally being highest in spring and summer, due to enhanced transportation of aerosols containing radioactive particles from stratosphere to troposphere during w...
