“…The 210 Po concentrations ranged from 0.10 to 0.39 mBq g À1 (mean: 0.23 AE 0.08 mBq g À1 , n ¼ 15) ( Table 1). This mean value is of the same magnitude as found in blood (Hasson and Cherry, 1966;Little and McGandy, 1966;Parfenov, 1974;Shabana et al, 2000). We observed that liquefied semen samples had a density almost equal to one.…”

“…In smokers, Po-210 levels are in fact significantly higher in blood (by 30%) [65, 80], urine (6-times higher) [81], liver, kidney, heart, and psoas muscle [82]. Little and McGandy estimated that Po-210 concentration in blood is 63.64 mBq/kg of blood in smokers and 28.12 mBq/kg of blood in non-smokers [83].…”

The alpha-radioactive polonium 210 (Po-210) is one of the most powerful carcinogenic agents of tobacco smoke and is responsible for the histotype shift of lung cancer from squamous cell type to adenocarcinoma. According to several studies, the principal source of Po-210 is the fertilizers used in tobacco plants, which are rich in polyphosphates containing radio (Ra-226) and its decay products, lead 210 (Pb-210) and Po-210. Tobacco leaves accumulate Pb-210 and Po-210 through their trichomes, and Pb-210 decays into Po-210 over time. With the combustion of the cigarette smoke becomes radioactive and Pb-210 and Po-210 reach the bronchopulmonary apparatus, especially in bifurcations of segmental bronchi. In this place, combined with other agents, it will manifest its carcinogenic activity, especially in patients with compromised mucous-ciliary clearance. Various studies have confirmed that the radiological risk from Po-210 in a smoker of 20 cigarettes per day for a year is equivalent to the one deriving from 300 chest X-rays, with an autonomous oncogenic capability of 4 lung cancers per 10000 smokers. Po-210 can also be found in passive smoke, since part of Po-210 spreads in the surrounding environment during tobacco combustion. Tobacco manufacturers have been aware of the alpha-radioactivity presence in tobacco smoke since the sixties.

“…Our obtained results of 210 Po activities in human blood are higher than results from Arabia, where the activity of 210 Po ranged from 0.91 to 4.56 pCi/l (from 33.67 mBq dm −3 to 168.72 mBq dm −3 ) in blood of smokers with an average value of 1.83 ± 0.63 pCi/l (67.71 ± 0.63 mBq dm −3 ). Blood samples of non-smoker showed 210 Po activity ranging from 0.61 ± 3.14 pCi/l (22.57–116.18 mBq dm −3 ) with an average value of 1.29 ± 0.61 pCi/l (47.73 ± 0.61 mBq dm −3 ) [ 18 ]. The mean value of smoker is significantly higher (about 30 %) than in non-smokers.…”

The determination of polonium 210Po in human blood samples is presented and discussed in this paper. The human blood samples were collected from patients of Medical University of Gdańsk with ischaemic heart disease (morbus ischaemicus cordis, MIC). The polonium concentrations in analyzed human blood samples are very differentiated. 210Po is of particular interest in public health and although is present in the environment in extremely low amounts, it is easily bioaccumulated to the human body. The study shows that the amount of 210Po that is incorporated into the human body depends on the food habits and some difference in its levels could be observed between smokers and non-smokers.
