When beta particles penetrate into a material, energy is transfered to the material and layers near the surface are ionized, corresponding to the penetration depth of the particles. Neutrinos were originally thought to be massless. As a result, beta radiation has a lower chance of penetrating deep within the body than alpha radiation. However, because they are charged particles, they encounter a greater interaction with matter. Charged particles are influenced by magnetic fields in order to move. As a general rule, a beta-emitting . They are much more deflected than the heavier alpha particles. stopped by clothing, or a few mm of aluminum. The rule of thumbs. What is the charge of an alpha particle. It is 1/100 that of alpha particles and 100 times as that of gamma rays. They are negatively charged particles. Because the electric field is a force that pushes particles in a specific direction, this is the case. -Alpha particles contain a stream of He++ ions, which are positive ions. In electron emission, also called negative beta decay . Why does the beta particle have a charge of? Beta particles occur with either negative or positive charge (- or +) and are known to be either electrons or positrons, respectively, therefore beta decay represents radioactive decay, in which a beta particle is emitted. Beta particles are more penetrating than alpha particles, but are less damaging to living tissue and DNA because the ionizations they produce are more widely spaced. Beta Particles. Alpha particles have a very low penetration power. Quarks are the only known particles whose electric charge comes in fractions of the elementary charge. If it's moving, THEN it's electric current, and current feels a force toward or away from magnets. Beta rays are high energy and speed electrons.
