Ionizing Radiation Detectors
- Alpha particle
A particle emitted during radioactive decay that is comprised of two protons and two neutrons, equivalent to the nucleus of a 4He atom.
- Beta particle
An electron or a positron (the positively charged antimatter twin of an electron) emitted during radioactive decay.
- Electron volt (eV)
A unit of energy measurement defined by the kinetic energy gained by a free electron when accelerated through a potential difference of 1 V; approximately equivalent to 1.602 × 10−19 J.
- Gamma radiation
Highly energetic electromagnetic radiation (energy greater than approximately 100 keV) emitted from the nucleus during radioactive decay.
- Ionizing radiation
Particles or light with sufficient energy to remove an electron from an atom or molecule.
A species of atomic nuclei, defined by the number of protons and neutrons present in the nucleus; nuclides are represented by chemical symbol and atomic mass number. Two examples are 12C (carbon-14, 6 protons and 8 neutrons) and 235U...
