WebThey have high energy and can kill cancer cells, as well as bacteria on food. They can also be used as a medical tracer. When gamma rays are used as medical tracers, a chemical containing the rays is injected into the body of a patient. An image is then formed when the gamma rays travel out of the body and are detected by a gamma camera. WebAn isotope emits gamma rays that easily pass through the body. The rays reach a detector outside the body, for example an x-ray machine or a ‘gamma camera’. In this way, the radioactive... summer jobs for school employees
