The emission of a positron also results in the creation of?
If you are talking about beta+ decay, then the emission of a positron is accompanied with the emission of an electron neutrino.
Where does the positron produced during positron emission come from?
In positron emission, the positron is produced from the nucleus of an atom when a proton is converted into a neutron and a positively charged positron. This process helps to make the nucleus more stable by decreasing the number of protons.
What Is geological positron emission?
Geological positron emission refers to the emission of positrons (positively charged electrons) from rocks or minerals. This phenomenon can be used in geological studies to understand rock properties, such as porosity and composition, by measuring the rate of positron emission. It is a valuable tool in geophysical exploration and understanding the subsurface structure of the Earth.
Mercury-201 undergoes positron emission?
In positron emission, a proton in the nucleus is converted into a neutron, leading to the emission of a positron and a neutrino. Therefore, in the case of Mercury-201 undergoing positron emission, the nucleus transforms into a new element with one less proton and one more neutron in its nucleus.
What radionuclide decays to Br-73 by positron emission?
Work backwards. Positron emission means (essentially) a proton decayed into a neutron/positron pair. The mass number remains the same, but the atomic number goes down one to Bromine. Krypton has an isotope that fits this bill.

What does the medical abbreviation PET mean?
Positron Emission Tomography
Which imagining system combines tomography with radionuclide tracers to produce enhanced images of selected body organs or areas?
positron-emission tomography(PET Scan)
What is the nuclear equation of positron emission of ca-37?
The nuclear equation for positron emission of Ca-37 is: 37Ca -> 37K + e^+ + v + γ This reaction involves the emission of a positron (e^+), resulting in the conversion of a calcium-37 nucleus to a potassium-37 nucleus, along with a neutrino (v) and a gamma ray (γ).
What is the nuclear equation for positron emission by sulfur 31?
If molybdenum-91 undergoes beta plus decay, or positron emission, the equation will look like this: 4291Mo => 4191Nb + e+ + ve In this reaction, a proton in the nucleus of the Mo-91 atom undergoes a change mediated by the weak interaction or weak force. This involves an up quark changing into a down quark, and the proton becomes a neutron. Nuclear transmutation takes place, and the Mo-91 atom becomes an atom of niobium, Nb-91. The positron, represented by e+, and a neutrino, the ve, will be ejected from the nucleus. Links can be found below if you wish to check facts and do some additional investigating.
What test do you have done to see if you had a stroke?
positron emission tomography (PET)
The emission of a positron also results in the creation of a?
When an atomic nucleus releases a positron, it has undergone beta plus decay. This nuclear transformation event also will release a neutrino. Use the link below for more information.
What are the advantages of Positron emission tomography?
PET scans can see inside the brain
