Radiation Safety Training Online Module

The goal of this module is to provide participants with the information to recognize radiation risk, and the skills and tools needed to safely and effectively minimize radiation doses and maintain both an actual and perceived safe working environment. It will discuss ionized radiation, radiometric quantities, sources of radiation, and the risks involved with the use of radiation equipment.
This course is intended for technologists, PAs, and nurses working in departments at Swedish (or in the surrounding hospitals/clinics) that use radiation therapy. Any health care professional that works with or in proximity to radiation therapy and examination stations may find this content beneficial.  Swedish Medical Staff, this is NOT the module required for credentialing, please see the Fluoroscopic Radiation module.

Learning Objectives
By attending this course, the participant will provide better patient care through an increased ability to:

  • Describe ionizing radiation
  • Define radiometric quantities and estimating doses of exposure
  • Review Occupational Radiation Dose Limits
  • Recognize risks and safety behaviors for radiation equipment both for staff and patients
  • Recognize the concept of ALARA (As Low As Reasonably Achievable)
  • Explain the basic principles of radiation protection
