  "id": "MLC-T-CHM-001079",
  "term": "Background radiation",
  "field": "Chemistry",
  "definition": "Ionizing radiation originating from natural sources, such as cosmic rays, terrestrial radionuclides in rocks and soil, and naturally occurring radioactive isotopes within the human body. It also includes radiation from man-made sources like medical procedures and nuclear fallout. This ubiquitous radiation contributes to the overall signal detected in radioanalytical measurements.",
