Are gamma rays positrons?
No, they are not.Gamma rays are photons - just like light. They are electrically neutral. They move at the speed of light. Positrons, also known as anti-electrons, have a positive charge. They move at speeds less than the speed of light.
What is the difference between alpha beta gamma rays?
Alpha rays are helium nuclei (two protons + two neutrons) and have a charge of +2; beta rays are either electrons or anti-electrons (positrons), with a charge of -1 or +1; gamma rays are high-energy light rays (photons).
What is the definition for radioactivity?
Spontaneous emission of ionizing radiation as a consequence of a nuclear reaction, or directly from the breakdown of an unstable nucleus; The radiation so emitted; including gamma rays, alpha particles, neutrons, electrons, positrons, etc
What types of particles does gamma radiation release?
Gamma radiation is not a particle, is it a high energy electromagnetic wave.
Beta radiation is made up of what?
There are 3 different types of radioactive decay. alpha decay, beta decay and gamma decay. alpha decay is composed of a helium nuclei, beta decay emit either electrons or positrons, and finally gamma decay in which high energy "rays" of photons. A positron is a positively charged electron (antimatter twin of the electron). See the natural decay series of U-238 and others to see which daughters emit beta to alpha or gamma. there is also the neutrino. I cant say we really know that much about it but basically it helps satisfy the law of conservation.
What are the particles called from a nuclear decay?
These are known as alpha, beta, and gamma rays. Alpha rays are helium-4 nuclei, beta rays can be electrons or positrons, gamma rays are high-energy electromagnetic waves.These are known as alpha, beta, and gamma rays.

How Positron emission tomography work?
A tracer courses through the bloodstream to the target organ, where it emits positrons. The positively charged positrons collide with negatively charged electrons, producing gamma rays.
When nuclear fusion occurs what form of radiation is released from the star?
Positrons and neutrinos are released by nuclear fusion.
How are gamma rays readable by photomultiplier-scintillator combinations produced by positron emission tomography?

When do radioactive isotopes occur?
A radioactive isotope is an unstable atom which emit radiations as alpha, beta, gamma, neutrons, positrons etc.
Are gamma rays positrons?
No, they are not.Gamma rays are photons - just like light. They are electrically neutral. They move at the speed of light. Positrons, also known as anti-electrons, have a positive charge. They move at speeds less than the speed of light.
If an element is radioactive what would be released from its nucleus?
Depending on the specific element and isotope it can release neutrons, alpha particles (Helium-4 nuclei), beta particles (electrons and positrons), and gamma radiation (energy in the form of electromagnetic radiation)
Where does sun comes from?
Through an internal thermonuclear fusion reaction, the sun uses four protons in a process called the proton-proton chain which results in the release of two positrons, two neutrinos, two gamma rays, helium, and energy.
Is Alpha Beta or gamma made from electrons?
Beta radiation is made from electrons (or positrons for inverse beta radiation). Alpha radiation is a helium nucleus, and gamma radiation is a high energy electromagnetic ray.
What types of radiation particles have no weight?
Gamma rays are the only ones. Alpha particles are helium nuclei, and Beta particles are electrons or positrons, all of these have mass.
Is radioactivity natural?
yes, radioactivity is natural. It is the natural process by which elements having neutron-proton ratio more than 1.5 disintegrate the nucleus to release particles like alpha particles, beta particles, gamma rays, positrons etc. This process continues until the nucleus of the atom is stable with the neutron-proton ration less than or equal to 1.5. Usually the natural process of radioactivity ends with the formation of Lead.
How does magnetism effect gamma radiation?
No. Gamma rays are photons (light particles). Photons are particles with no mass, no charge and no magnetic moment.
