Radiation Exposure and Risk-Benefit Analysis
Radiation exposure occurs when individuals are exposed to ionizing radiation, which can alter
cellular structure and DNA. Sources include medical imaging (X-rays, CT scans), nuclear power,
and natural background radiation.
The risk-benefit analysis weighs potential health risks (e.g., cancer) against the benefits (e.g.,
accurate diagnosis or treatment). For example, a CT scan delivers higher radiation than a standard
X-ray but may be justified if it provides critical diagnostic information.
Protection strategies include ALARA (As Low As Reasonably Achievable), shielding, limiting
exposure time, and maintaining safe distances.
