  "term": "Beta Particle",
  "field": "Environment",
  "definition": "1. An electron or positron emitted by the nucleus of a radioactive atom. Beta particles can be stopped by a layer or two of clothing or by a few millimeters of a substance such as aluminum. They can go through the skin and cause radiation damage, such as skin burns. As with alpha particles, beta particles are most hazardous when they are emitted inside the body by inhaled or ingested radionuclides.\n\n2. A form of particulate ionizing radiation made up of small, fast-moving particles. Some beta particles are capable of penetrating the skin and causing damage such as skin burns. Beta-emitters are most hazardous when they are inhaled or swallowed.",
