Why are positrons produced from some nuclei but alpha or beta radiation come from other nuclei?
Positrons are a type of beta radiation (along with electons). Let's check things out to figure out why some nuclei are positron emitters. Positron emission (beta + decay) follows after the conversion of a neutron in an atomic nucleus into a proton. In atomic nuclei that have an excess number of neutrons to be stable, this is a common form of decay. It directly assists an unstable nucleus in getting closer to the "line of stability" of the N-Z plot. As beta + decay has a higher probablity for nuclei with excessive numbers of neutrons, beta - decay has a higher probability for nuclei with shortages of neutrons. In general, alpha decay is reserved for the heaviest radionuclides. We see radium, uranium, plutonium and a number of other elements from the upper end of the Periodic Table as having alpha decay as a possibility among their methods of decay.

What are the 3types of radation?
The three main types of radiation are alpha, beta, and gamma radiation. Alpha radiation consists of helium nuclei, beta radiation involves electrons or positrons, and gamma radiation is electromagnetic radiation. Each type has different properties and levels of penetration.
What types of atoms realease nuclear radiation?
Atoms with unstable nuclei, such as uranium, radium, and plutonium, can release nuclear radiation. This radiation can take the form of alpha particles (helium nuclei), beta particles (electrons or positrons), or gamma rays (high-energy photons).
What are the three major types of radiation in order weakest to strongest?
The three major types of radiation in order from weakest to strongest are alpha, beta, and gamma radiation. Alpha radiation consists of helium nuclei and is the weakest, beta radiation consists of fast-moving electrons or positrons, and gamma radiation is high-energy electromagnetic radiation.
What are the types of radiactivity?
The three main types of radioactivity are alpha radiation, beta radiation, and gamma radiation. Alpha radiation consists of helium nuclei, while beta radiation consists of electrons or positrons. Gamma radiation is a high-energy form of electromagnetic radiation.
Is beta the same kind of radiation as alpha but does not have particles?
No Alpha radiation is essentially a helium nucleus - a couple of protons and neutrons bound together as a particle Beta radiation is an electron or positron - still a particle but not the same kind of particle as alpha.
What is radioactivity and what is the difference between alpha beta and gamma radiation?
Alpha radiation is helium-4 nuclei - i.e., each alpha particle consists of 2 protons and 2 neutrons.Beta radiation is either electrons or positrons (= anti-electrons). Gamma radiation is high-energy photons.
Is Alpha Beta or gamma made from electrons?
Electrons are not directly involved in the creation of alpha, beta, or gamma radiation. Alpha radiation consists of helium nuclei (2 protons and 2 neutrons), beta radiation is made of electrons (beta-minus) or positrons (beta-plus), and gamma radiation is a high-energy electromagnetic radiation.

What are types of nuclear radiation?
The most common are: gamma radiation (high energy photons), beta particles (high energy electrons or positrons) and alpha particles (high energy helium nuclei).
What is the Method used in alpha beta gamma?
Alpha, beta, and gamma refer to the types of radiation emitted by radioactive materials. Alpha radiation consists of helium nuclei, beta radiation consists of electrons or positrons, and gamma radiation consists of high-energy photons. Each type of radiation has its own properties and can interact differently with matter.
What are the three major types of radiation in order weakest to strongest?

What type of radiation emitted by radioactive nuclei is negatively charged?
A Beta- particle is an electron, which has negative charge.Here are some other types: Alpha is a helium nucleus, which is 2 protons and 2 neutrons (having positive charge). Positron is the antiparticle to electron. Positrons have positive charge. Gamma does not have charge. Neutrons do not have charge. Neutrinos do not have charge.
What are the types of radiactivity?

What are Waves usually given off during nuclear reactions?
Three common types of waves given off during nuclear reactions are gamma rays, alpha particles, and beta particles. Gamma rays are high-energy electromagnetic radiation, alpha particles are helium nuclei consisting of two protons and two neutrons, and beta particles are high-energy electrons or positrons.
What radioactive emission is not a particle?
Gamma rays are not particles, but highly-ionizing electromagnetic radiation of a very short wavelength.The other major atomic "radiation" is in the form of alpha particles (He nuclei) or beta particles (electrons, or positrons).
Is beta the same kind of radiation as alpha but does not have particles?
No Alpha radiation is essentially a helium nucleus - a couple of protons and neutrons bound together as a particle Beta radiation is an electron or positron - still a particle but not the same kind of particle as alpha.
