Student Learning Outcomes

  • Identify and describe various types of regulatory provisions and radiation safety measures for adult patients associated with fluoroscopy.
  • Describe the radiation equipment used for pediatric patients.


Exploration of radiation safety measures in the field of fluoroscopy for both fixed and mobile units. Emphasis will be placed on time, distance, shielding, radiobiology, isometric curves, and inverse square law, as well as reduction of radiation exposure to both patients and personnel. Restricted to licensed California Radiologic Technologists to meet continuing education requirements set forth by the Department of Public Health's Radiologic Health Branch.

Course Objectives

The student will be able to:

  1. Identify radiation safety measures for the pediatric patient
  2. Describe how fluoroscopic equipment functions and can be utilized safely
  3. Define and discuss the regulations and guidelines associated with mobile image intensified units
  4. Describe the regulatory provisions and radiation safety measures of fluoroscopic equipment and the adult patient
