Polonium-210 is an alpha emitter.
I am pretty sure it Alpha radiation because you cannot be effected by it if it is outside the body, all other types of radiation can penetrate the skin
Polonium-210 has 126 neutrons.
The half life of polonium 210 is 138,376 days.
Polonium-210 has 84 protons, 84 electrons and 126 neutrons.
He was poisoned with a polonium-210 pellet when he was stabbed with the point of an umbrella. He died shortly afterward from radiation poisoning.
Polonium-210 decay to lead-206.
Polonium-210 become lead-206 after the emission of an alpha particle.
Polonium -210, this unstable isotope of Polonium (named after Poland) is an alpha emitter with a half life of 138.376 days, it decays into Pb.
Polonium is between the most poisonous materials; the LD5o for polonium-210 is 1 microgram.
