All nuclear decay has some kind of particle or particles associated with it. Even the metastable decay of 4399Tcm, a gamma at 142.7 Kev, is considered to be a particle emission, because a gamma is a photon, and a photon is an elementary particle, per our understanding of modern quantum mechanics and particle physics, even though it has no mass at rest state.
Radioactive decay; beta decay is a type of radioactive decay in which a beta particle (an electron or a positron) is emitted
gamma decay
because the total enegy of the decay is carried by beta particle and the nutrino.

Beta Particle
This is beta decay, specifically beta plus decay. The beta particle that appears is the positron, which is the antimatter particle of the electron. Links can be found below for more information.
the decay of neutron into proton givesz small praticle called negative beta particle
An electron during beta decay.
An alpha particle
A beta particle is either an electron, or a positron (aka "anti-electron").
A beta particle is produced in a process called beta decay, in which a neutron becomes a proton or vise versa. There are two forms of beta decay:normal beta decay - a neutron becomes a proton, a beta particle (i.e. electron) and an antineutrinoantibeta decay - a proton becomes a neutron, an antibeta particle (i.e. positron) and a neutrino
