Radioactivity coincidence counter system. Physicist using a coincidence counter system to produce a primary standard for radioactive tracer solutions. The disc contains a sample of radionuclides, also known as radioactive isotopes (atoms with an unstable nucleus). Radionuclide tracers are often used in environmental monitoring, radiopharmaceuticals production, nuclear physics and medicine. Photographed at the National Physical Laboratory in Teddington, UK.
