Question
Explain why positron-emitting isotopes are not usually produced in nuclear reactors.
Step 1
Positron-emitting isotopes, also known as positron emitters, are radioactive isotopes that decay by emitting positrons, which are the antimatter counterparts of electrons. This process is known as beta plus (β+) decay. Show more…

The nuclide ${ }^{7}$ Be is unstable and decays into ${ }^{7} \mathrm{~L}$ i by electron captore. Why does it not decay by positron emission?
Why is the following situation impossible? In an effort to study positronium, a scientist places 57 $\mathrm{Co}$ and 14 $\mathrm{C}$ in proximity. The 57 Co nuclei decay by $\mathrm{e}^{+}$ emission, and the 14 $\mathrm{C}$ nuclei decay by $\mathrm{e}^{-}$ emission. Some of the positrons and electrons from these decays combine to form sufficient amounts of positronium for the scientist to gather data.
Explain why most fission products formed in a nuclear reactor decay by beta emission rather than undergoing another kind of nuclear decay.
