Consider that the half-life of polonium-210 is 140 days. what approximate daily percentage of decay does polonium-210 demonstrate? % (round to two : use the rule of 70 backwards by dividing by the half-life period instead of the rate.) what percentage of the original amount of polonium-210 would be left after 425 days of decay? % (round to two decimals.)
