We often think of nuclear radiation as harmful, and it is. But it can also be beneficial. It can be used for energy, as tracers, for food preservation, and for treating cancer. This PowerPoint presentation, describes the detection of radiation with a Geiger counter. It also describes a nuclear power plant and explains some of its workings. Radiation's other uses are explored as well. Worksheets on this topic are available free of charge on my website at www.evanschemistrycorner.com.
