Polonium in cigarette smoke and radiation exposure of lungs
Polonium (Po), the most volatile of naturally-occurring radionuclides in plants, was analysed in three common brands of cigarettes produced in Portugal. The analyses were carried out on the unburned tobacco contained in cigarettes, on the ashes and butts of smoked cigarettes and on the mainstream smoke. Po in tobacco displays concentrations ranging from 3 to 37 mBq g, depending upon the cigaret...

متن کاملPolonium-210 budget in cigarettes.
Due to the relatively high activity concentrations of (210)Po and (210)Pb that are found in tobacco and its products, cigarette smoking highly increases the internal intake of both radionuclides and their concentrations in the lung tissues. That might contribute significantly to an increase in the internal radiation dose and in the number of instances of lung cancer observed among smokers. Samp...
متن کاملPolonium-210 activity in human hair samples and factors affecting its accumulation
Background: Due to the presence of radioactive minerals such as monazite, the beach sand of the west coast of Kanyakumari exhibits high natural background radiation. Hair is a good indicator of radionuclides in the human body. An attempt is taken to measure the 210Po activity in human hair samples and the factors affecting it. Material and Methods: 210Po activity was analysed in 47 ind...
متن کاملBioaccumulation of polonium-210 in marine copepods
210Po, a naturally occurring radioisotope that is ubiquitous in seawater, is especially enriched in proteinaceous tissues of marine organisms and may therefore be useful as a tracer of organic carbon flux in marine systems. Due in part to its biomagnification in marine food chains, 210Po provides the largest radiation dose to any organism under natural conditions. To better understand the exten...
