Toenail Clippings Offer Clues to Radon Exposure and Lung Cancer Risk
Scientists have discovered that toenail clippings can reveal long-term exposure to radon, a radioactive gas linked to lung cancer, potentially aiding early diagnosis in non-smokers or those unaware of their exposure. The method detects lead isotopes from radon decay in toenails, showing promise for broader screening and risk assessment.
