Gamma rays. Since they are electromagnetic waves, they travel at the speed of light.
Gamma Ray
Beta radiation is made from electrons (or positrons for inverse beta radiation). Alpha radiation is a helium nucleus, and gamma radiation is a high energy electromagnetic ray.
The gamma ray is not a particle but is just an EM wave that transmits energy.
From Physics Forums The alpha particle has a 2+ charge, beta has 1- charge, and the gamma is neutral (no charge). The beta particle could also have a 1+ charge if it undergoes positron emission [a proton turns into a neutron and a positron (the "anti-electron")]
Alpha and Beta Radiation are types of ionizing radiation. They are both charged particles though Alpha is heavier than the particle Beta.
aplha, beta, gamma
Alpha and beta are not electromagnetic radiation.
Gamma Ray
ernest Rutherford is the answer....
a. an alpha particle

The gamma ray is not a particle but is just an electromagnetic wave that transmits energy.
The gamma ray because a photon does not have electric charge and is thus does not experience force in a EM field. All the others are charged particles
Alpha, beta, gamma, X-ray, neutron.
Various radioactive substances such as Plutonium and Uranium give off a combination of alpha, beta and gamma rays as the isotope decays.
The alpha particle is much more massive than a beta particle. A beta particle is an electron, which has very little mass. An alpha particle is a helium nucleus, and consists of two protons and two neutrons.
