Which Ray has highest ionizing power?
Alpha particlesAlpha particles have approximately four times the mass of a proton or neutron and approximately 8,000 times the mass of a beta particle.
Because of the large mass of the alpha particle, it has the highest ionizing power and the greatest ability to damage tissue..

Which has greater Ionising Power Alpha or Beta?
Alpha particle has more ionising power than beta particle. This is because alpha particle has more mass and charge than beta particle.
Why is Alpha more Ionising than gamma?
Alpha particles are bulky, so they interact heavily with the surrounding materials. This means they can ionize a lot of atoms on the very short distance they travel. … That’s why alpha radiation is much more harmful to the human body than gamma radiation (by a factor of 20).
