The radioactivity in tobacco leaves collected from 15 different regions of Greece and before cigarette production was studied in order to find out any association between the root uptake of radionuclides from soil ground by the tobacco plants and the effective dose induced to smokers from cigarette tobacco due to the naturally occurring primordial radionuclides , such as 226Ra and 210Pb of the ...

Measurements of fallout radioactivity in Greenland in 1977 are reported. Strontium-90 (and Cesium-137 in most cases) was determined in samples of precipitation, sea water, vegetation, animals, and drinking water. Estimates are given of the mean contents of 90Sr and 137Cs in the human diet in Greenland in 1977.

in this work, 137cs activity concentration of soil in five depths and in six meteorology stations in terms of bq/kg has been measured. for each thirty soil's samples, parameters such as kind of soil, density and hydraulic coefficient of transmission were determined. correlation coefficient between 137cs activity concentration and raining average, hydraulic coefficient of transmission and s...

Quantification of uncertainties in doses from intakes of radionuclides is important in risk assessments and epidemiologic studies of individuals exposed to radiation. In this study, the uncertainties in the doses per unit intake (i.e., dose coefficients) for ingestion of 131I, 137Cs, and 90Sr by healthy individuals have been determined. Age-dependent thyroid dose coefficients were derived for 1...

In a recently published letter [1], it was noticed that in volume 1181 of The Annals of the New York Academy of Sciences (2009), dedicated to the Chernobyl accident, references to non-professional publications (mass media, websites of unclear affiliation, etc.) were used to back up scientific views. Another theme which was commented on in the letter [1] was the reduction of radiocesium levels i...

The impact of the radioactive fallout caused by the accident at the Chernobyl NPP on the Baltic Sea is discussed in this paper. The fallout from Chernobyl was very unevenly distributed in the drainage area of the Baltic Sea; the Bothnian Sea and the eastern part of the Gulf of Finland received most of the deposition. This was reflected in the activity concentrations of the main fallout nuclides...

BACKGROUND After the Chernobyl nuclear accident on April 26, 1986, all children in the contaminated territory of the Narodichesky region, Zhitomir Oblast, Ukraine, were obliged to participate in a yearly medical examination. We present the results from these examinations for the years 1993 to 1998. Since the hematopoietic system is an important target, we investigated the association between re...

The radionuclides released from the Fukushima Daiichi nuclear power plant in 2011 pose a health risk. In this study, we estimated the 1st-year average doses resulting from the intake of iodine 131 (131I) and cesium 134 and 137 (134Cs and 137Cs) in drinking water and food ingested by citizens of Fukushima City (∼50 km from the nuclear power plant; outside the evacuation zone), Tokyo (∼230 km), a...
