Is polonium 214 dangerous?
Polonium 214, the penultimate descendant, does not have enough time to be inhaled by itself into the lungs as its half-life is of only 1.6 hundredths of a second. The alpha ray emitters which fix themselves to the inside of the body are dangerous.
How does polonium kill you?
If polonium-210 enters the body, through inhalation, swallowing, broken skin, the results can be fatal. By mass, polonium-210 is one of the deadliest toxins, around 250 billion times more toxic than hydrogen cyanide.
