Illicit Trafficking of Natural Radionuclides

AIP Conference Proceedings, 2008
Natural 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 ...

Evaluation of radiological risks due to natural radionuclides in the soil of Khanaqin district, Diyala, Iraq

Physica Scripta
This study aimed to evaluate the radiological impacts in Khanaqin, located in the Diyala Governorate, Iraq. The specific activities of natural radionuclides of 238U, 232Th, and 40K in soil samples were investigated by collecting thirty composite soil ...

Soil-Soybean Transfer Factor of Natural Radionuclides in Different Soil Textures and the Assessment of Committed Effective Dose.

Radiation Protection Dosimetry, 2020
From three different soil textures (clay, silt and sand), 36 soil and soybeans samples were accumulated from the agricultural area of EL-Mynia governorate in Upper Egypt, between (27°36'19.44″N; 30°30'14.14″ E) and (28°48'28.45″ N; 31°00'32.27″ E).

Natural radionuclides in drinking waters in Serbia

Applied Radiation and Isotopes, 2012
Gross 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, 1985
Concentration 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

1982
From 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, 1977
Radium-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, 1984
p6osystems 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, 2013
In 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.
