During industrial non-destructive testing of deep-sea oil pipelines, technicians use high-energy gamma (γ\gammaγ) radiation to inspect structural welds for internal micro-fissures.
State one specific hazard to human health that arises from accidental exposure to this gamma radiation.
25 exam-style questions on Edexcel GCSE Physics 5.4 Uses and dangers of EM radiation, covering 5.4.1 Dangers of electromagnetic radiation, 5.4.2 Uses of electromagnetic radiation, 5.4.3 Radio waves and oscillations in circuits, and 5.4.4 Changes in atoms and nuclei generating radiation. Each one has a worked solution and a mark scheme showing where the marks go.
