considered that the new particle was emitted from the nucleus together with the electron or beta particle in the process of beta decay and had a mass similar...

battery) is a type of nuclear battery that generates electric current from beta particles (electrons or positrons) emitted from a radioactive source, using semiconductor...

[citation needed] Ionizing subatomic particles include alpha particles, beta particles, and neutrons. These particles are created by radioactive decay, and...

beta decay transition is the change in state of an atomic nucleus undergoing beta decay. When undergoing beta decay, a nucleus emits a beta particle and...

(often called a beta particle in this context) and an electron antineutrino: n0 → p+ + e− + ν e Again, the neutron is not an elementary particle but a composite...

Beta burns tend to be shallow as beta particles are not able to penetrate deeply into a body; these burns can be similar to sunburn. Alpha particles can...

Beta (UK: /ˈbiːtə/, US: /ˈbeɪtə/ ; uppercase Β, lowercase β, or cursive ϐ; Ancient Greek: βῆτα, romanized: bē̂ta or Greek: βήτα, romanized: víta) is the...

force acting on charged particles, typically alpha and beta particles, due to interaction with matter, resulting in loss of particle kinetic energy. Stopping...

occurs following the emission of an alpha or a beta particle. Thus, gamma decay usually follows alpha or beta decay. Other more rare types of radioactive...

deflection, it was clear that alpha particles were much more massive than beta particles. Passing alpha particles through a very thin glass window and...
