His illness was sudden and unexplained. After his death, traces of the radioactive isotope polonium 210 (210Po) were found in the tissues of his body. It appears that the radioactive poison was administered in Litvinenko’s tea, and he died of radiation poisoning. His body contained 8.00 micrograms of 210Po (the element Po with an atomic mass of 210.0), which is 200 times the lethal ingested dose of 50.0 nanograms. How many atoms of 210Po does 8.00 micrograms represent? One gram is 109 nanograms and 106 micrograms. Poisoning of Alexander Litvinenko Note: Show all work for this question for full credit.
