What is the positron issue?
Positron issue is a by -product of a radioactive decay known as beta plus disintegration. In the Beta Plus process, the unstable neutron and protons in the nucleus of the atomic of the excess proton to neutrons causes unstable balance. Several other particles, including positron, are issued during the conversion process. Positron is a special type of particle known as beta particles because it is a by -product of beta break -up. In addition to neutron production, Beta Plus has a break -up to neutrino and positron production. Positron is a counterpart to the electron antimatter, which means that when positrons and electrons are knocked down, they destroy and create gamma rays. This feature is important for researchers who use the Positronion emis in their work.
Radioactive disintegration causes a change in the properties of the atom because the balance of protons and neutrons in the nuclei. This process explains why an element can exist in multiple forms fromEach isotope has a different balance of protons and neutrons. Many isotopes are unstable, experiencing a rapid disintegration, and radioactive particles in this process. This process also explains the uneven distribution of elements on the ground, as unstable elements over time decompose into more stable forms, leading to higher concentration of stable elements.
The medical community uses positive emissions for the type of medical imaging study known as Positron emission tomography (PET). In this study there are isotopes known to produce positrons, into the body, and follow when they move the body and produce gamma rays. Isotopes with short -circuit lives that do not cause body damage are selected so that PET scan will not be dangerous and the study study can be combined with other imaging techniques such as magnetic resonance imaging to get a complete picture of what is happening inside the patient's body.
Scanning of petsAnd allows doctors to display the functions of the body, possibly especially in the brain. Scanning is not invasive and provides an attractive alternative to surgical surgery to see the inside of the body and can provide a large amount of useful information. Such scanning is used in medical diagnostics and medical research, while positron emission tomography is brain scanning particularly popular for neurology scientists who are interested in brain functions.
