What else can I help you with?
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.
Antimatter practical use for pet scans?
In PET scans, antimatter (positrons) is used in the form of a radiopharmaceutical to create images of metabolic activity in the body. When the radiopharmaceutical is injected into the body, the positrons emitted from it annihilate with electrons in the body, producing gamma rays. These gamma rays are detected by the PET scanner to create detailed images of organs and tissues.
What rays have more energy beta or gamma rays?
Gamma rays have more energy than beta rays. Gamma rays are a form of electromagnetic radiation with the highest energy in the electromagnetic spectrum, while beta rays are high-energy, high-speed electrons or positrons.
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 do gamma rays consist of only electrons pure energy only protons beta particles?
Gamma rays consist of pure energy in the form of electromagnetic radiation. They do not consist of electrons or protons. Beta particles are high-energy electrons or positrons emitted during certain types of radioactive decay, but they are not present in gamma rays.
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 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.
Radioactive substances that emit positrons are used in scans?
Positron emission tomography (PET) scans use radioactive substances that emit positrons to detect metabolic activity in the body. These substances are injected into the body and, as they decay, they emit positrons that interact with electrons to produce gamma rays. The gamma rays are then detected by a PET scanner to create detailed images of the body's functions.
When nuclear fusion occurs what form of radiation is released from the star?
Positrons and neutrinos are released by nuclear fusion.
What kind of rays does uranium 235 and plutonium 239 release?
Uranium-235 and plutonium-239 release alpha, beta, and gamma rays during the process of radioactive decay. Alpha particles are helium nuclei, beta particles are high-energy electrons or positrons, and gamma rays are electromagnetic radiation.
How are gamma rays readable by photomultiplier-scintillator combinations produced by positron emission tomography?
the tracer courses through the bloodstream to the target organ, where it emits positrons. The positively charged positrons collide with negatively charged electrons,
When do radioactive isotopes occur?
A radioactive isotope is an unstable atom which emit radiations as alpha, beta, gamma, neutrons, positrons etc.
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)
Antimatter practical use for pet scans?

These gamma rays are detected by the PET scanner to create detailed images of organs and tissues.
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 rays have more energy beta or gamma rays?
Gamma rays have more energy than beta rays. Gamma rays are a form of electromagnetic radiation with the highest energy in the electromagnetic spectrum, while beta rays are high-energy, high-speed electrons or positrons.
