Which type of radiation detector produces bright flashes of light when exposed to radiation?

A. Moderating rod
B. Geiger counter
C. Scintillation counter
D. Film badge

Answer :

Final answer:

Option c) A scintillation counter is a device that emits bright flashes of light in response to radiation, differentiating it from other detectors like Geiger counters and film badges.

Explanation:

The type of radiation detector that produces bright flashes of light when exposed to radiation is a scintillation counter. A scintillation counter includes a scintillator, which is a material that emits light when excited by ionizing radiation. This light is then converted into an electric signal by a sensor. It is different from a Geiger counter that detects radiation by ionization of gas in a tube, and a film badge, which uses photographic film to measure exposure.
