What type of radioactive decay has the largest and most damaging particles?

Answer 1

The largest radioactive emission is the alpha particle, which consists of two protons and two neutrons, and is, in effect, a helium ion.

The term radioactive particle is used for a small radioactive mass made up of radionuclides. This is different from a radioactive emission, and is not specific as to size.

Answer 2

Gamma radiocative dacay is the most powerful form of decay, It can penatrate the entire body. Beta is the next more powerful decay, but can esaily be avoided by wearing a layer of clothing, Alpah is the next more powerful, but can be blocked by a piece of paper. However, If Alpha or Beta decay is inside the body, It will cause a great deal of damage and will lead to a fatal sickness such as Radiation poisioning, bone cancer, rotting of the bone marrow, lung cancer, etc... Raduim one of the most radioactive materials, yet does no harm to the body unless indigested. For example in the early 1900's The U.S. Radium Corporation was being sued for having thier workers lick the paint brushes used to paint radium on watch dials (because of is iluminesence) and it caused them rotting of the jaw bones and they all died. Know as the Radium Girls they took their case to the national level and a famous play was writen about the entire incedent.
