Radiation physics

Introduction Radiation comes in different forms of energy in motion. Doses of radiation and the area of interest are important considerations when imaging patients, particularly during percutaneous procedures. Methods Reference texts in essential physics, principles of radiation imaging, and radiation dosimetry were reviewed. Results Dose, exposure to radiation, and total body radiation delivery are reviewed and graphically tabulated. Conclusion Each institution will monitor radiation dose delivered to the individual; however, individual physicians have the responsibility to protect themselves and their patients against excessive radiation exposure by knowing appropriate dosages and biological risks.
