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 primarily emits alpha radiation, which consists of two protons and two neutrons. This type of radiation has a low penetrating power and is highly ionizing, making it hazardous if ingested or inhaled.
A post-mortem examination suggested Mr Litvinenko had died after being poisoned with the radioactive substance polonium-210.
Polonium-210 has 126 neutrons.
Polonium-210 has 84 protons, 84 electrons and 126 neutrons.
Polonium-210 decay to lead-206.
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 become lead-206 after the emission of an alpha particle.
The symbol Po-210 represents the radioactive isotope of polonium with an atomic number of 84 and a mass number of 210. Polonium-210 is a highly toxic substance that emits alpha particles during radioactive decay.
Polonium is a natural radioactive element.
POLONIUM-210
The specific radioactivity of polonium-210 is 4,5.10E3 Ci/g.
