Gamma spectroscopy. Scientist loading a sample into a high resolution gamma spectrometer. The spectrometer is lined with copper to prevent radiation leaks. Gamma spectrometry is used to test for, and measure, gamma decay from atomic nuclei. Gamma decay is the emission of gamma rays, a type of high energy electromagnetic radiation. Different elements emit gamma rays at different characteristic energies. It is these energies that the spectrometer measures and records. Gamma spectroscopy can be used to determine radiation levels in environmental and geological samples. Photographed at the National Physical Laboratory, Teddington, UK.
