7.3 Biological dosimetry using chromosomal aberrations
4 min read•july 31, 2024
Chromosomal aberrations are like radiation's fingerprints on our DNA. They're changes in our chromosomes that happen when we're exposed to radiation. Scientists can count these changes to figure out how much radiation someone's been exposed to.
This method, called biological dosimetry, is super helpful when we don't have other ways to measure radiation exposure. It's used in emergencies, for worker safety, and in long-term health studies. It's a key tool in understanding how radiation affects our bodies.

Biological dosimetry measures using in living organisms exposed to ionizing radiation
Complements physical dosimetry by estimating absorbed dose based on biological effects rather than direct radiation measurements
Proves particularly useful in scenarios lacking physical dosimeters or during accidental radiation exposure
Enables retrospective dose estimates, allowing assessment of past radiation exposures
Supports radiation protection efforts, emergency response to radiation accidents, and long-term health risk assessment of radiation workers
Plays a crucial role in epidemiological studies by establishing dose-response relationships for various health effects of radiation exposure
Applications in Radiation Protection and Research
Assesses occupational exposure in radiation workers (nuclear power plant employees, medical radiologists)
