Shielding in Radiology
About this Program
Medical uses of radiation have grown rapidly over the past two decades, and it remains the largest source of manmade ionizing radiation exposure to the U.S. population. Additionally, non-ionizing radiation from Magnetic Resonance Imaging (MRI) also presents unique hazards. Engineering controls from properly designed and installed safety barriers (radiation shielding) are among the most effective strategies for protecting individuals from the hazards unique to Radiology. MRI safety is imperative. Therefore, understanding the design and evaluation of shields for radioactive sources, x-ray-producing equipment, and MRI systems—issues covered in effective radiation safety training courses—is essential for maintaining a safe imaging environment.
This 4-part rad safety training webinar provides an in-depth look at shielding common Radiology modalities, including radiography, mammography, fluoroscopy, CT, MRI, Nuclear Medicine, SPECT/CT, PET/CT, and Radiopharmaceutical Therapy. Plus, our radiation safety course is designed to provide continuing education for potential CAMPEP credits.
The instructors who lead our webinars, including these radiation safety training sessions, are true professionals with years of experience in their fields. They are ready, willing, and able to share their radiation shielding expertise with you.
