“…In soils, 210 Po is in equilibrium with 210 Pb, suggesting that the 210 Pb in the soil is the main source of 210 Po irreversibly adsorbed on clay and organic colloids in the soil (Parfenov, 1974). The average activity concentration levels of 210 Po in various soils are in the range of 20e240 Bq kg À1 (Al- Arifi et al, 2006;Hasanen, 1977;Karunakara et al, 2000;Myrick et al, 1983).…”

“…This explains the high uranium concentrations in tissues of smokers than those of non-smokers. There are some studies that indicate high concentrations of uranium and alpha emitters in different biological samples of smokers that including blood, urine, hair, and tooth [36,37]. Figure 3 explains the average uranium content in the abnormal and normal tissues samples as a function of residential site.…”

The technique of nuclear fission track analysis with solid state nuclear track detectors CR-39 has been applied to determine concentrations of uranium in cancerous samples of human tissues that excised from patients in the three key southern Iraqi governorates namely, Basrah, Dhi-Qar, and Muthanna. These provinces were the sites of intensive military events during the Gulf Wars in 1991 and 2003. The investigation was based on the study of 24 abnormal samples and 12 normal samples for comparing the results. These samples include four types of soft tissues (kidney, breast, stomach and uterus). The results show that uranium concentrations in the normal tissues ranged between (1.42-4.76 lg kg -1 ), whereas in the cancerous tissues ranged between (3.37-7.22 lg kg -1 ). The uranium concentrations in the normal tissues were significantly lower than in the abnormal tissues (P \ 0.001).

“…The main intake route of natural 210 Po and 210 Pb is ingestion with foodstuffs, although some studies have reported that smoking also represents a significant route of intake (Al-Arifi et al 2006;Khater 2004). According to the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR), the annual intake of 210 Po ranges from 18 Bq in Argentina to 220 Bq in Japan.…”

A study to determine activity concentrations of (210)Pb and (210)Po in the urine of certain Finnish population groups was conducted, to investigate the variation in natural background level of urinary excretion. The study participants were divided into three groups mainly based on their diet. The first group comprised recreational fishermen and the second group represented people consuming more reindeer meat than an average Finn, while people using drinking water with very high activity concentrations of (210)Po were selected for the third group. The fourth group was a control group. The mean urinary excretion of (210)Po in groups 1 and 2 was 73 and 100 mBq d(-1), respectively. These values were higher than the value of the control group (20 mBq d(-1)) and the mean values reported in the literature. The mean daily urinary excretion of (210)Pb in groups 1 and 2, 70 and 52 mBq d(-1), was also slightly higher than that in the control group (32 mBq d(-1)). In contrast, the excretion rates of both (210)Po and (210)Pb for the members of group 3 were one to two orders of magnitude higher than those reported in the literature. This was clearly due to the elevated levels of natural radionuclides in their drinking water. The present study demonstrates the importance of possessing good knowledge of the background levels, in order to allow the determination of the additional exposure due, for example, to the malevolent use of radiation.
