Beta
A beta particle is a negative electron. A positive electron is a Positron.
A radiation consisting of a single electron is known as beta radiation. This type of radiation occurs during beta decay when a neutron transforms into a proton, electron, and antineutrino. Beta radiation is commonly emitted by radioactive substances and has the ability to penetrate materials and cause ionization.
No, a delta particle is not a fast moving electron given off by a nucleus during radioactive decay. The electron described here is a beta particle, and specifically a beta minus particle. It is given off in (no surprise) beta minus decay. A link to a related question can be found below.
It is still called an "electron".On the other hand, an electron that results from radioactive decay is also known as "beta radiation"; but please note that "beta radiation" may also refer to an antielectron.
gamma radiation!
An electron is fired into the reactor core containing the radioactive material, usually uranium, and as it hits the radioactive nucleus the uranium atom breaks down forming two daughter nuclei and emitting another electron (beta radiation particle) which continues as a chain reaction.
This particle is a neutron:neutron-----------proton + electron + neutrino
Alpha emission is a 4helium nucleus, which behaves like a particle. Beta emission is an electron, which behaves like a particle. Gamma emission is a photon, which behaves like a particle. Experiments can also be set up to show their wavelike properties (for alpha, beta, and gamma radiation).

When a hydrogen-3 nucleus undergoes radioactive decay, it emits a beta particle (specifically an electron) and an anti-neutrino to transform into helium-3.
In unstable neuclei where there are 'too many' neutrons, a neutron will convert to a proton and an electron - that electron is ejected from the nucleus and is called a beta particle. It is important that we call this electron a beta particle because it is derived by radioactive disintegration in the nucleus and not an 'orbital' electron.
