In positron-emission tomography (PET) used in medical research and diagnosis, compounds containing unstable nuclei that emit
positrons are introduced into the brain, destined for a site of interest in the brain. When a positron is emitted, it goes only a short
distance before coming nearly to rest. It forms a bound state with an electron, called "positronium", which is rather similar to a
hydrogen atom. The binding energy of positronium is very small compared to the rest energy of an electron. After a short time the
positron and electron annihilate. In the annihilation, the positron and the electron disappear, and all of their rest energy goes into two
photons (particles of light) which have zero mass; all their energy is kinetic energy. These high energy photons, called "gamma rays", are
emitted at nearly 180° to each other.
What energy of gamma ray (in MeV, million electron volts) should each of the detectors be made sensitive to? (The mass of an electron
or positron is 9 x 10-31 kg.…
