NO about 0.99 the speed of light howeaver they are electrons ( or positrons ) so exibit wave properties so there velocity cannot be mesured due to uncirtanty
Beta particles cannot penetrate very far into solids because they have low velocity and moderate mass. Their interaction with the solid material causes them to lose energy and slows down their penetration capability.
The relative velocity of alpha with respect to beta is the velocity of alpha minus the velocity of beta. The relative velocity of beta with respect to gamma is the velocity of beta minus the velocity of gamma. The relative velocity of alpha with respect to gamma is the velocity of alpha minus the velocity of gamma.
A minimum shielding for beta particles typically includes materials like plastic, glass, or water. These materials are effective at stopping low-energy beta particles due to their ability to absorb and scatter the particles, reducing their penetration depth. Thicker shielding may be required for higher-energy beta particles.
Lead is a common low-density shield used to stop beta particles. Its high atomic number and density make it effective at absorbing and stopping the particles, protecting against their harmful effects.
Beta particles can pass through materials with low density such as air, paper, or even human skin. However, they have difficulty passing through denser materials such as lead, concrete, or thick metal. These materials effectively block or absorb the beta particles, preventing them from penetrating further.
Low energy beta particles, say, from tritium, are called soft beta particles.

Beta particles have a very low penetrating power; an aluminium foil of 3-4 mm is a sufficient shielding.
Alpha particles can be blocked by a block of lead due to their relatively low penetrating power, while beta particles may require a thicker shield, such as a piece of aluminum or plastic, depending on their energy. Lead is not as effective at blocking beta particles as it is for alpha particles.

An Alpha Particle is a fast, bare Helium nuclei composed of two protons, two neutrons, and no electrons, that is ejected at high velocity from a decaying nuclei. A Beta Particle is an electron or positron, ejected at extremely high velocity from a decaying nuclei. Both alpha particles and protons are Bosons. Both beta particles and electrons are Leptons. Their relationships are similar because the electron and proton are both components of atoms. The beta and alpha particles are both fragments ejected from decaying atoms.
Beta particles have a negative charge, while alpha particles have a positive charge. Beta particles are electrons or positrons, while alpha particles are helium nuclei consisting of two protons and two neutrons.
Beta particles are not stopped by a paper sheet.
Beta particles are high-energy electrons emitted during beta decay. Beta particles are typically absorbed by materials that are capable of stopping or slowing down the fast-moving electrons, such as materials with high atomic numbers like lead or thick layers of shielding materials like concrete. The penetration ability of beta particles is relatively low compared to gamma radiation.
