d. spiral
Scintillation counters are widely used in medical imaging used to measure radioactive contamination, radiation measurement gauges, radiation measurement testing, nuclear power plant safety, and radiation.
Scintillation is the process by which the energy of a specific radiation interacting with a certain amount of sensitive material (called a scintillator) is converted into electromagnetic waves. The frequencies of the electromagnetic waves emitted are in or near the visible spectrum.
A scintillator is a substance that exhibits scintillation, the property of luminescence, when excited by ionizing radiation. When a luminescent material collides with an approaching particle, it absorbs the energy and glows (that is, it re-emits the absorbed energy in the form of light).
