Geiger-Muller detectors are particularly useful in scenarios that involve detecting and measuring radiation, especially in environments where contamination control is a priority. They operate efficiently when a high voltage is applied, which allows for the ionization of the gas within the detector. This ionization process leads to the production of a measurable electrical pulse in response to incoming radiation, making it a vital tool for quickly and accurately detecting radioactive materials.

The effectiveness of Geiger-Muller detectors in contamination control is due to their sensitivity to low levels of radiation, enabling them to identify contaminated surfaces or environments. This capability is crucial in fields such as nuclear industry, research laboratories, and medical facilities, where managing and monitoring radiation exposure is essential for safety.

While the role of high voltage is significant for the detector's functionality, the integration of both high voltage operation and contamination control reflects the broader application of Geiger-Muller detectors in practical scenarios, and therefore, the answer encompasses these relevant aspects.
