It's the other particle that Po-210 (the chemical symbol for Polonium) emits that is lethal. A very energetic alpha particle. Alpha emission is a third way nuclei have of relieving internal stress.

alpha decay. In alpha decay. Thus polonium-210 (mass number 210 and atomic number 84, i.e., a nucleus with 84 protons) decays by alpha emission to lead-206 (atomic number 82). Read More.
