how are gamma rays different from alpha and beta particles?

Gamma rays (γ) are weightless packets of energy called photons. Unlike alpha and beta particles, which have both energy and mass, gamma rays are pure energy. Gamma rays are similar to visible light, but have much higher energy.

The key difference between gamma rays and X-rays is how they are produced. Gamma rays originate from the settling process of an excited nucleus of a radionuclide after it undergoes radioactive decay whereas X-rays are produced when electrons strike a target or when electrons rearrange within an atom.

Beta particles can be either electrons or positrons. These particles are originated from atomic nuclei during the beta decay. ... The main difference between beta particle and electron is that beta particle can have either +1 charge or -1 charge whereas electron has a -1 charge.

FYI: Beta and gamma radiation are also dangerous; they both chip away at DNA and damage living tissue. However, beta particles are smaller, move faster, and have less charge than alpha particles—they are less damaging than alpha particles by a factor of 1000. Gamma radiation is pure energy and has no mass or charge.

Alpha radiation consists of helium-4 nucleus and is readily stopped by a sheet of paper. Beta radiation, consisting of electrons, is halted by an aluminium plate. Gamma radiation is eventually absorbed as it penetrates a dense material. Lead is good at absorbing gamma radiation, due to its density.

In some fields of physics, they are distinguished by their origin: Gamma rays are created by nuclear decay, while in the case of X-rays, the origin is outside the nucleus.

Gamma rays are the strongest from of radiation. This is what makes nuclear radiation so dangerous. This high energy form of radiation can damage human tissue and cause mutations. ... Gamma rays differ from alpha and beta waves in their composition.

Because they consist of charged particles, alpha and beta radiation can also be deflected by magnetic fields . Just as with electric fields, gamma radiation is not deflected by magnetic fields.

Because the source of emission is different. Alpha rays are produced by the decay of the proton rich nucleus and beta rays are emitted by the decay of neutron rich nucleus.

Each type of radiation has a different ability to penetrate materials. ... The alpha radiation transfers more energy to an absorber than beta or gamma radiation. Alpha radiation is absorbed by the thickness of the skin or by a few centimetres of air. Beta radiation is more penetrating than alpha radiation.

Alpha and beta rays are deflected in opposite directions in a magnetic field because they are oppositely charged—alpha are positive and beta negative. Gamma rays have no electric charge and are therefore undeflected.

Forces on a charged particle. Alpha particles are positively charged, beta particles are negatively charged, and gamma radiation is electrically neutral . This means that alpha and beta radiation can be deflected by electric fields , but gamma radiation cannot.

There are four major types of radiation: alpha, beta, neutrons, and electromagnetic waves such as gamma rays. They differ in mass, energy and how deeply they penetrate people and objects. The first is an alpha particle.

Alpha particles are released by high mass, proton rich unstable nuclei. The alpha particle is a helium nucleus; it consists of two protons and two neutrons. It contains no electrons to balance the two positively charged protons. ... Gamma rays are emitted by most radioactive sources along with alpha or beta particles.

Answer Expert Verified Gamma rays consist of pure energy. Beta particles consist of one electron that is released at high speeds from an unstable nucleus and an alpha particle is a helium nucleus.

Beta particles are a type of ionizing radiation and for radiation protection purposes are regarded as being more ionising than gamma rays, but less ionising than alpha particles. The higher the ionising effect, the greater the damage to living tissue.
