Tag: Ionizing radiation

According to the International Atomic Energy Agency (IAEA), medical uses of ionizing radiation account for the largest proportion of human-made radiation exposure. Understanding **what does medical exposure mean** is crucial for patients, caregivers, and medical professionals alike, as it is a deliberate and medically supervised process.

Radiosensitivity in human tissue is inversely proportional to the degree of cell differentiation. This principle explains why the brain, along with the muscle and nervous system tissues, is the bodily organ least affected by radiation due to its highly specialized, non-dividing cells.

According to the U.S. Nuclear Regulatory Commission, ALARA is a fundamental regulatory requirement for all radiation safety programs. This guiding principle, which stands for "As Low As Reasonably Achievable," is designed to minimize exposure to ionizing radiation and protect both workers and the public.
