What are the three main types of ionizing radiation used in diagnostic radiology?

The three main types of ionizing radiation used in diagnostic radiology are X-rays, gamma rays, and particle radiation. X-rays are widely utilized in medical imaging due to their ability to penetrate body tissues and create images of the internal structures. Gamma rays, which are emitted from radioactive materials, also penetrate tissue well and are used in certain types of imaging, such as nuclear medicine scans.

Particle radiation, which can include alpha particles, beta particles, and neutrons, also contributes to diagnostic applications, although it is less commonly used than X-rays and gamma rays. These types of radiation are significant in their ability to ionize atoms, leading to the creation of images for diagnostic purposes.

Other options presented contain forms of radiation that either do not ionize atoms (such as UV rays, infrared rays, and sound waves) or are not primarily used in diagnosing medical conditions. Therefore, option B correctly identifies the three primary forms of ionizing radiation that play crucial roles in the field of diagnostic radiology.
