Which method is commonly used for detecting radiological threats?

• A. Infrared cameras
• B. Geiger-Muller counters
• C. Thermal imaging
• D. Sonar devices

Answer: (B)

The method commonly used for detecting radiological threats is through Geiger-Muller counters. These devices are specifically designed to measure ionizing radiation, which includes alpha particles, beta particles, and gamma rays. They function by utilizing a gas-filled tube that generates an electrical pulse when radiation enters it, providing a readout that indicates the level of radiation present in the environment. Geiger-Muller counters are widely used due to their portability, ease of use, and effectiveness in detecting various types of radiation, making them a critical tool for safety personnel in identifying potential radiological hazards. Other methods, while useful in their own contexts, do not have the capability to detect radiation directly. For instance, infrared cameras and thermal imaging are more suitable for detecting temperature differences rather than radiation, and sonar devices are employed for underwater detection, thus they are not applicable for radiological threat assessment.
