Radiation exposure can be monitored through photographic film darkening or by deploying___________________?
Show answer Hide answer
Answer: B. GM counter
Explanation
Radiation exposure can be monitored through photographic film darkening or by deploying a GM counter. A Geiger-Müller counter detects ionizing radiation particles quickly, producing audible clicks and digital readouts. The correct choice identifies the GM counter as a standard electronic instrument for radiation measurement. Ionizing radiation includes alpha, beta, and gamma rays capable of stripping electrons from atoms. Inside a GM counter, radiation ionizes filling gas, creating an electrical pulse measured by circuitry. Safety protocols require radiation workers to wear personal monitoring devices to track cumulative exposure.
Nuclear power plants and medical radiology departments enforce strict radiation safety monitoring protocols. Emergency responders carry portable radiation detectors to assess environmental hazards during nuclear accidents. Research laboratories utilize these sensitive instruments to ensure compliance with occupational safety limits. A ratio autoanalyser is a laboratory instrument used for chemical assays rather than measuring radiation. A neutron probe measures soil moisture content using neutron scattering rather than general radiation exposure. A dosimeter is a badge tracking cumulative dose, whereas the GM counter is the active detector instrument.
