Free Online Course - Radiation Emergencies

About this course

Radiation is all around us, both natural and man-made. Although everyone is exposed to radiation every day, misunderstanding about radiation is common. This course will provide learners with an overview of issues in relation to radiation emergencies. In particular, it introduces the basics of radiation, health effects of acute exposure to radiation and measures in response to a radiation emergency.

What you will learn

There are three sections in this e-learning module on radiation emergencies:

  • Section One is an introduction about the basics of radiation. For instance, the difference between ionizing and non-ionizing radiation and the different ways to measure radiation.
  • Section Two is about the health effects of acute exposure to radiation. For instance, the mechanisms by which ionizing radiation damages our cells and the clinical manifestations of acute exposure are introduced.
  • Section Three discusses the measures in response to a radiation emergency. For instance, the principles of emergency department preparedness, the use of personal protective equipment and the procedures to decontamination are presented.

Target Audience

Although this module is primarily for first responders to prepare for radiation emergencies, it is also suitable for the general public who are interested in knowing more about this topic. Healthcare professionals may also find this module useful in case they want to refresh their knowledge on radiation.


Upon successful completion of this course, you will be able to:

  • Explain the causes and consequences of a radiation emergency
  • Identify the health risks of a radiation emergency
  • Demonstrate the procedures for preparedness and protection for a radiation emergency
