Rousing the dragon: Polonium production for neutron generators in the Manhattan Project

American Journal of Physics, 2019
During the Manhattan Project, the rare element polonium (Po) was synthesized by neutron bombardment of bismuth in nuclear reactors for use in neutron-generating triggers that were used to initiate the fission chain reactions in the Hiroshima and Nagasaki

Natural levels of polonium-210 in urine

Journal of Radiological Protection, 2018
This paper presents a review and analysis of available data on background levels of polonium-210 in urine. It was established that 819 measurements could be considered to correspond to natural background levels, excluding a large number of values ...

Polonium-210 in Man

Journal of Occupational and Environmental Medicine, 1965
The part played by polonium-210 in contributing to the biologically effective radiation dose received by humans in a variety of environments is described. The selection of data presented has been dictated to a large extent by the availability of post-mortem and other specimens and cannot be considered comprehensive.

The Chemistry of Polonium

Quarterly Reviews, Chemical Society, 1957
Publisher Summary The heaviest elements in every group of the Periodic Table have a special interest because of the marked change in the properties, which occurs in passing down a group, thus, in the heaviest member, the maximum group valency is achieved with difficulty, if at all.
