How do you measure background radiation
WebThere are three types of survey meters: ion chambers, scintillation detectors, and fission detectors. Ion chambers contain a gas that can be ionized by radiation. The ions are … WebAlthough we cannot see or feel the presence of radiation, it can be detected and measured in the most minute quantities with quite simple radiation measuring instruments. Radiation Dose Sunlight feels warm because our body absorbs the infra-red rays it contains. But, infra-red rays do not produce ionization in body tissue.
