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%.

210Po in Human Saliva of Smokeless Tobacco Users
Health Physics, 2017The occurrence and mobility of Po in oral smokeless tobacco products (STPs) were determined because its effects on human health must be taken into account. This research was subdivided into two parts: determination by alpha spectrometry of the Po activity concentration in 16 oral smokeless tobacco products of different brands purchased in local ...

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.

Polonium 210Po in the phytobenthos from Puck Bay
Journal of Environmental Monitoring, 2003The aim of the work was to determine the 210Po content in phytobenthos species (seaweeds and angiosperms) from Puck Bay (southern Baltic). Alpha spectrometry was used to measure and calculate the activities and concentrations of polonium 210Po in the phytobenthos.

Investigations of the potential bioavailability of 210Po in some foodstuffs
Science of The Total Environment, 1995Extraction of 210Po from lamb's liver, pig's kidneys, mussel flesh and brown crabmeat with a series of solvent systems has been used to gain some insight into the uncertainty about the gastrointestinal absorption factor for Po incorporated into foodstuffs.

Modelling the behaviour of 210Po in high temperature processes
Journal of Environmental Radioactivity, 2011In several Naturally Occurring Radioactive Material (NORM) industries, relatively high temperatures are used as part of their industrial processes. In coal combustion, as occur in other high temperature processes, an increase of the activity concentration of every natural radioisotope is produced both, in residues and by-products.

Contamination of a Soft-drink Manufacturing Plant by 210Po
Health Physics, 1990An investigation was undertaken of the contamination of equipment and flooring by 210Po, released from a static eliminator source, at a soft-drink manufacturing plant. The detection and establishment of extent of contamination, development of decontamination and control procedures and difficulties in implementing those procedures are discussed ...

To estimate the dietary intakes of 210Pb and 210Po for the Japanese adults and their annual effective doses, 210Pb and 210Po were measured for 240 daily diet samples collected at two locations of Ishikawa Prefecture in Japan over three years by duplicate portion studies.

Temporal changes of 210Po in temperate coastal waters
Science of The Total Environment, 1998The temporal variation of Polonium-210 (210Po) was examined in coastal sea water, the mussel Mytilus edulis, the winkle Littorina littorea and green alga Ulva lactuca in order to investigate the entry of 210Po into the marine food chain. More than 99% of 210Po in the water column occurred in the particulate phase.

Concentration of 210Po and 210Pb in the diet at the Marshall Islands
Science of The Total Environment, 1994The concentrations of 210Po and 210Pb have been determined in many local foods consumed by societies residing on different atolls in the Marshall Islands. The average daily intake of these two naturally occurring radionuclides from local and imported food is estimated to be 2.18 and 0.36 Bq, respectively. Local foods contribute 87% of the 210Po and 47%
