“…The confirmation of the incidents of thyroid cancer (41), hepatocellular carcinoma (42), leukemia (43), and risks of acute and chronic exposure to uranium (44), has emphasized the importance of awareness of somatic and genetic consequences of contamination with uranium isotopes. Its correlation with atmospheric testing of nuclear weapons has been reconfirmed in recent reports of the levels of actinides, clearly associated with years of nuclear testing and radioactive fallout in the sea mammals of the northern Pacific (45). The revisited Hiroshima and Nagasaki studies indicate that not only the physical but also psychological impact of the chronic consequences of the use of nuclear weapons have been associated with a prevalence of psychiatric disorders, anxiety, and somatization of symptoms among the victims who were present in the Japanese cities at the time of explosion (46).…”

The internal contamination with depleted uranium (DU) isotopes was detected in British, Canadian, and United States Gulf War veterans as late as nine years after inhalational exposure to radioactive dust in the Persian Gulf War I. DU isotopes were also identified in a Canadian veteran's autopsy samples of lung, liver, kidney, and bone. In soil samples from Kosovo, hundreds of particles, mostly less than 5 mm in size, were found in milligram quantities. Gulf War I in 1991 resulted in 350 metric tons of DU deposited in the environment and 3-6 million grams of DU aerosol released into the atmosphere. Its legacy, Gulf War disease, is a complex, progressive, incapacitating multiorgan system disorder. The symptoms include incapacitating fatigue, musculoskeletel and joint pains, headaches, neuropsychiatric disorders, affect changes, confusion, visual problems, changes of gait, loss of memory, lymphadenopathies, respiratory impairment, impotence, and urinary tract morphological and functional alterations. Current understanding of its etiology seems far from being adequate. After the Afghanistan Operation Anaconda (2002), our team studied the population of Jalalabad, Spin Gar, Tora Bora, and Kabul areas, and identified civilians with the symptoms similar to those of Gulf War syndrome. Twenty-four-hour urine samples from 8 symptomatic subjects were collected by the following criteria: 1) the onset of symptoms relative to the bombing raids; 2) physical presence in the area of the bombing; and 3) clinical manifestations. Control subjects were selected among the sympotom-free residents in non-targeted areas. All samples were analyzed for the concentration and ratio of four uranium isotopes, 234 U, 235 U, 236 U and 238 U, by using a multicollector, inductively coupled plasma ionization mass spectrometry. The first results from the Jalalabad province revealed urinary excretion of total uranium in all subjects significantly exeeding the values in the nonexposed population. The analysis of the isotopic ratios identified non-depleted uranium. Studies of specimens collected in 2002 revealed uranium concentrations up to 200 times higher in the districts of Tora Bora, Yaka Toot, Lal Mal, Makam Khan Farm, Arda Farm, Bibi Mahro, Poli Cherki, and the Kabul airport than in the control population. Uranium levels in the soil samples from the bombsites show values two to three times higher than worldwide concentration levels of 2 to 3 mg/kg and significantly higher concentrations in water than the World Health Organization maximum permissible levels. This growing body of evidence undoubtedly puts the problem of prevention and solution of the DU contamination high on the priority list.

“…AMP is an inorganic compound that selects the caesium exclusively and has high adsorption capacity (Suss and Pfrepper, 1981). This method has been widely applied to sea-water samples in order to enrich the Cs concentration (Aoyama et al, 2000;Nabyvanets et al, 2000;Djingova and Kuleff, 2002;Baskaran et al, 2003). However, this radiochemical extraction for a soil sample should be emphasized by its effective background suppression, thereby significantly lowering the minimum detection limit.…”

We investigate the caesium concentrations in soils in mountain areas near Gori nuclear power plant in Korea, focusing on the measurement limits to the 134 Cs. In order to lower the minimum detectable amount (MDA) of activity for the 134 Cs, we have used the ammonium molybdophosphase (AMP) precipitation method to get rid of the 40 K existing in natural radioactivity, which reduces the MDA activity about ten times smaller than those without the AMP precipitation method. The MDA results for the 134 Cs were found to be in the range between 0.015 and 0.044 Bq/kg-dry weight. In order to diminish the background, we also have measured a part of the soil samples in Yangyang, a small town in the east coast of Korea. However, it turns out that in order to detect the 134 Cs in the samples the MDA should be reduced to the level of mBq/kg-dry weight.
