PET Scan Positron emission tomography (PET) scans use radiation to diagnose and track health conditions and monitor medical treatments by revealing how parts of a patient’s body function ( Figure 4 ). Alpha decay occurs when the nucleus of an atom spontaneously ejects an alpha particle. The oxide formed offers a high resistance to corrosion. The population is decreasing by 8% every year, therefore. And so what that tells us is that when we started, we had four plus 28. 2Al + 3H 2 O --> 2Al 2 O 3 + 3H 2. Like magnesium, aluminium burns in oxygen with a brilliant white flame. The most stable isotope is 222 Rn, which is a decay product of 226 Ra, a decay product of 238 U. What separates this type of decay process from alpha or beta decay is that no particles are ejected from the nucleus when it undergoes this type of decay. Nuclear binding energy is the energy required to split an atom’s nucleus into protons and neutrons. Write a balanced nuclear equation to represent this decay reaction.
