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 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...
متن کاملPolonium-210 poisoning in London: hypochondriasis and public health.
INTRODUCTION In November 2006, a Russian dissident died from radioactive Polonium-210 (210Po) poisoning in London. Providing reassuring messages during a public health incident may be ineffective for individuals with high health anxiety (hypochondriasis). METHODS Members of the public who called a 24-hour telephone helpline were offered a follow-up call by a health protection specialist for r...
متن کاملPolonium 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...
