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.
What Is geological positron emission?
loss of a positron. 0:+1B
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.
Positron-emission tomography forms images of body tissues this is known as what?
PET scan
Why do positron emission and electron capture have the same effect on a nucleus?
The reason positron emission and electron capture have the same effect on the nucleus of an atom is because the resulting atom undergoes nuclear transformation, and the new element will have one less proton and one more neutron than the precursor element. Both of these nuclear changes are interesting, so let's look a bit more closely. In positron emission (also called beta plus decay), a proton in the nucleus of an atom "changes" into a neutron and a positron is ejected. This results in one less proton in that nucleus (naturally), and the creation of a new element. And because the proton had become a neutron, the nucleus has the same number of nucleons and a similar atomic weight. In electron capture, a nucleus with "too many" protons will actually "pull in" an electron and take it into its nucleus. This electron will "combine" with a proton, and a neutron will result. This will reduce the number of protons in the nucleus, and the creation of a new element -- just like in positron emission. Links to related questions can be found below.

How do positron emission and electron capture change an atom?
After positron emission or electron capture the atomic number is decreased with one.
What does the medical abbreviation PET mean?
Positron Emission Tomography
What does PET stand for brain scan?
Positron Emission Tomography
What is positron emission tomography used to diagnose?
Positron Emission Tomography (PET) scans are used in hospital mainly to detect cancers, especially cancers that have metastasised or spread into surrounding tissue.
Which imagining system combines tomography with radionuclide tracers to produce enhanced images of selected body organs or areas?
positron-emission tomography(PET Scan)
What test do you have done to see if you had a stroke?
positron emission tomography (PET)
What is the use of arsenic 74?
Arsenic 74 can be used as a positron emitter in PET - Positron Emission Tomography, the scope is to identify tumors.
