210Po AND 210Pb ACTIVITY IN CHINESE CIGARETTES
Health Physics, 2009The radon decay products lead-210 ((210)Pb) and polonium-210 ((210)Po) are known components of tobacco. China is the world's largest producer and consumer of cigarettes, yet no comprehensive published reports of the (210)Pb and (210)Po activity concentrations in Chinese cigarettes are available.

210Po AND 210Pb INHALATION BY CIGARETTE SMOKING IN ITALY
Health Physics, 2007210Po and its precursor 210Pb in cigarette smoke contribute a significant radiation dose to the lungs of smokers. In this work, the concentration of 210Po was determined in 17 of the most frequently smoked cigarette brands in Italy. Samples of tobacco, fresh filters, ash, and post-smoking filters were analyzed; 210Po was determined by alpha ...

210Po and 210Pb Intake by the Portuguese Population
Health Physics, 1995Through analysis of 210Po and 210Pb in the diet, the average ingestion rate for the Portuguese population is estimated at 1.2 and 0.47 Bq d-1 per capita for 210Po and 210Pb, respectively. Detailed analysis of foods indicate that seafood alone contributes up to 70% of the 210Po ingestion rate, whereas cereals, vegetables, and meat altogether contribute ...

210Pb targets for nuclear spectroscopy
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1987Abstract The preparation of metallic 210Pb targets by vacuum evaporation condensation is described. Lead-210, which is highly radioactive, is available as nitrate in 3M HNO3. Solid Pb(NO3)2 is extracted from this solution and subjected to a reductive evaporation procedure. A special-shaped evaporation crucible yields a collection efficiency of 2.8 mg/

Journal of Radioanalytical and Nuclear Chemistry, 2018
As a continuation of previous work (Kmak et al. in J Radioanal Nucl Chem 314:985–989, 2017), an isotope generator column based on the 210Pb decay chain has been made to produce highly radiopure 210Po. Two replicate studies were performed on AG 50Wx8 columns with an average yield of 90.4 ± 1.9%.

210Pb (rad) in Inhabitants of a Caribbean Island
Health Physics, 1965Abstract The mean concentration in vertebrae of Puerto Ricans was 0.118 pC 210Pb/g ash. The value in males, 0.133 pC/g ash, was significantly higher than the 0.088 pC/g ash in females. These values are significantly lower than those in similar groups of mid-continent (Midwestern U.S.) residents, 0.196 for males and 0.156 for females.

The activities of 210Po and 210Pb in cigarette smoked in Tunisia
Radiation and Environmental Biophysics, 2020In this study, the activity concentration of polonium 210 in cigarette for Tunisian consumers was investigated by alpha spectrometry. After chemical digestion of tobacco, 210Po was extracted, auto-deposited on disc and measured. The activity of 210Pb was assessed after radioactive equilibrium was achieved.

Zeitschrift für Physik A Hadrons and Nuclei, 1997
High spin states in nuclei in the 208Pb region were populated in deep inelastic collisions of 136Xe and 208Pb projectiles with thick 208Pb targets at about 50 MeV above the Coulomb barrier. Prompt and prompt-delayed γ-ray coincidences were measured. Four new states above the 8+ isomer in 210Pb were found and spins and parities assigned from theoretical

Levels of 210Po and 210Pb in cigars
Journal of Radioanalytical and Nuclear Chemistry, 2002210Po and 210Pb concentrations have been determined in 58 cigar brands manufactured in 11 countries. Cuban and American cigars showed the lowest 210Po content. The mean levels of 210Po in Brazilian, European and Dominican cigars were almost identical and somewhat lower than the levels observed for cigars from other Latin American countries.

210Pb and 210Po in medicinal plants
Radiochemistry, 2015The activity concentrations of 210Pb and 210Po in 16 samples of medicinal plants sold in St. Petersburg pharmacies were determined. The activity concentrations of 210Pb and 210Po, recalculated to the sample fabrication dates, vary in the range from
