Irradiation and contamination

Irradiation and contamination

Side-by-side comparison of irradiation from a sealed source and contamination by radioactive dust on skin and in lungs Radioactive materials are useful in medicine, safety devices, and electricity generation, but the risk depends on how the radiation interacts with matter. A key first step is separating irradiation from contamination.

  3. /6.2 Uses and hazards

Step-by-step lessons on OCR GCSE Physics 6.2 Uses and hazards, covering 6.2.1 Contamination and irradiation, 6.2.2 Half-life and radiation hazards, 6.2.3 Medical uses of nuclear radiation, 6.2.4 Nuclear fission and chain reactions, and 6.2.5 Nuclear fusion. Each one builds up to exam-style questions. Paper 2 and Paper 4 include synoptic questions that draw on Topics P1–P4, so revisit earlier topics before final exams rather than treating each paper as self-contained.
