Illicit Trafficking of Natural Radionuclides
AIP Conference Proceedings, 2008Natural radionuclides have been subject to trafficking worldwide, involving natural uranium ore (U 238), processed uranium (yellow cake), low enriched uranium ( 20% U 235), radium (Ra 226), polonium (Po 210), and natural thorium ore (Th 232). An important prerequisite to successful illicit trafficking activities is access to a suitable logistical ...

Natural radionuclides in drinking waters in Serbia
Applied Radiation and Isotopes, 2012Gross alpha and beta activities, (3)H, (226)Ra, (232)Th and (40)K activities were measured in bottled mineral water produced in Serbia in order to assess its radiological quality. In 11 samples of tap water and in 1 sample of spring waters gross alpha and beta activity were determined.

Natural radionuclides in mineral waters
Science of The Total Environment, 1985Concentration levels of natural radionuclides in mineral waters have been studied in several European countries. In the Federal Republic of Germany in recent years a nationwide investigation was carried out by several institutions. The concentrations of 226Ra, uranium isotopes, 210Pb and 210Po found are similar to those in other European countries ...

Natural Radionuclides in the Environment
1982From the point of view of environmental research the significance of natural radioactive elements in the environment is twofold: one is the effects of ionizing radiation from these radionuclides to organisms living on the earth, especially man, and the other is the possible applications of natural radionuclides existing in situ as tracers for ...

Natural radionuclides in industrial and rural soils
Science of The Total Environment, 1977Radium-226, lead-210, uranium and thorium are dispersed in the environment by fly ash emitted by coal fuelled power stations. Concentrations of these nuclides have been determined in fly ash from three power stations and in soils collected in six industrial and twenty rural regions.

Radionuclides in natural terrestrial ecosystems
Science of The Total Environment, 1984p6osystems to be found in the maritime temperate zone are described. The part played by vegetation, animals and soils in the distribution and movement of radionuclides is discussed, with particular reference to natural systems. Biomass activities have been compiled for 137Cs and 239 + 240Pu in woodland and moorland ecosystems.

Activity size distribution of some natural radionuclides
Radiation Protection Dosimetry, 2013In this study, the results concerning the activity size distribution of the long-lived ((210)Pb) radon decay product aerosols and the thoron decay product aerosols ((212)Pb) and ((7)Be) of the outdoor atmosphere are presented. Also, the mass size distribution of the aerosol particles is determined.

Natural radionuclides in bottled water in Austria
Journal of Environmental Radioactivity, 2003Concentration levels of 226Ra, 222Rn and 210Pb were analyzed in domestic bottled waters commercially available in Austria. Concentrations up to 0.23 Bq/l, with a geometric mean of 0.041 Bq/l were found for 226Ra. Concentrations for 222Rn ranged from
