Radiography: radiation safety

ffelis

Introduction

  • Radiation is a form of energy:
    • Ionizing radiation (eg X-rays) has sufficient energy to ionize atoms and cause damage to biological tissues. The source of ionizing radiation includes for example X-Ray generators and radio-active material.
    • Non-ionizing radiation (eg UV, microwaves, radio waves) is less energetic and unable to cause ionization.
  • It is essential to follow rigid safety guidelines when dealing with ionizing radiation that is a serious safety hazard because:
    • It is invisible.
    • It is painless.
    • It penetrates and interacts with biological tissues to produce:
      • Cumulative effects.
      • Latent effects, which may manifest at a later time.
