Alpha spectroscopy C016 / 3753
Alpha spectroscopy. Scientist loading a sample that has been dried onto a metal disc into an alpha spectrometer. Alpha spectrometry is used to test for, and measure, alpha decay from atomic nuclei. Alpha decay is the emission of an alpha particle, which consists of two protons and two neutrons. It is a form of radioactive decay. Different elements emit alpha particles at different characteristic energies. It is these energies that the spectrometer measures and records. Alpha spectroscopy can be used to determine radiation levels in environmental and waste samples. Photographed at the National Physical Laboratory, Teddington, UK

EDITORS COMMENTS
This print captures a moment of scientific exploration at the National Physical Laboratory in Teddington, UK. In this image, an esteemed European male scientist is seen diligently loading a dried sample onto a metal disc within an alpha spectrometer. The process being conducted here is known as alpha spectroscopy, which involves testing and measuring the alpha decay from atomic nuclei. Alpha decay refers to the emission of an alpha particle consisting of two protons and two neutrons. As a form of radioactive decay, different elements emit these particles at distinct characteristic energies. It is precisely these energies that the spectrometer measures and records with great precision. The significance of alpha spectroscopy extends beyond theoretical knowledge; it plays a crucial role in determining radiation levels in environmental and waste samples. This invaluable technique aids researchers in comprehending radioactivity levels present in various substances. The photograph showcases not only cutting-edge equipment but also highlights the dedication and expertise possessed by scientists like our protagonist who tirelessly work towards unraveling complex chemical mysteries. With his focus unwavering, he represents countless individuals committed to advancing our understanding of physics and radionuclides. Captured by Andrew Brookes for Science Photo Library, this image serves as a testament to human curiosity and ingenuity while shedding light on the fascinating world of alpha spectroscopy at one of Britain's most prestigious research institutions – the National Physical Laboratory.
