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 کاملAn experimental study on the bioaccumulation and turnover of polonium-210 and lead-210 in marine shrimp
The experimental accumulation of 210Po and 'lOPb from seawater alone and from seawater and food was studied in the laboratory with the benthic shrimp Lysrnata seticaudata. Shrimp accumulated both radionuclides from water for 21 d, reaching whole body concentration factors [CF = (Bq g' of shrimp wet wt)/(Bq ml-' filtered water)] of 139 k 28 for "OPo and 682 + 149 for 'l0Pb. When uptake was from ...
متن کاملSuspected radioactive contamination: evaluation of 45 Israeli citizens potentially exposed to polonium-210 in London.
The lethal poisoning of Alexander Litvinenco with the radioactive element polonium-210, and the risk that many civilians (including Israeli citizens) who were in the same location in London at the same time were exposed to radiation, was an unprecedented event in the western world. This was only the second known death due to 210Po, a natural alpha radiation-emitting element. A task team was cre...
