The unstable nuclide is called the parent nuclide; the nuclide that results from the decay is known as the daughter nuclide.The daughter nuclide may be stable, or it may decay itself.Ernest Rutherford’s experiments involving the interaction of radiation with a magnetic or electric field (Figure 2) helped him determine that one type of radiation consisted of positively charged and relatively massive α particles; a second type was made up of negatively charged and much less massive β particles; and a third was uncharged electromagnetic waves, γ rays.We now know that α particles are high-energy helium nuclei, β particles are high-energy electrons, and γ radiation compose high-energy electromagnetic radiation.Figure 3 summarizes these types of decay, along with their equations and changes in atomic and mass numbers.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).

The alpha particle removes two protons (green) and two neutrons (gray) from the uranium-238 nucleus.The loss of an inner shell electron leaves a vacancy that will be filled by one of the outer electrons.As the outer electron drops into the vacancy, it will emit energy.The scans it produces can be used to image a healthy brain (b) or can be used for diagnosing medical conditions such as Alzheimer’s disease (c).(credit a: modification of work by Jens Maus)O () and incorporated into a glucose analog called fludeoxyglucose (FDG).

  1. The documents could be a turning point in the yearslong campaign by anti-human-trafficking groups and Congress to crack down on Backpage’s persistent hosting of prostitution ads — including postings of underage girls and boys that have been linked to a slew of gruesome murders in the US and abroad.
