Beta-Another form of radioactive decay is the emission of a beta particle, or electron.

Alpha and beta particles are almost certainly already through those packages.

They fear gamma rays and neutrons, alpha particles and beta particles.

What's more, Strontium 90 emits beta particles, not alpha.

That was the dangerous kind, because both beta particles and gamma rays could penetrate clothing and skin.

Contrary to beta particles, alpha particles have a short path length and display a high lineic energy transfer.

That process continues in the waste dumps, where used hot rods exchange neutrons and expel alpha and beta particles, gamma rays, and heat.

The existence of the balloon increases the penetration of the beta particles and maintains the source within a location away from the vessel wall.

(He also discovered beta particles.)
