Introduction to Radiation

COURSE NO: Y03-004
Introduction to Radiation
Course Highlights

This online engineering PDH course provides an overview of the types of radiation, the health effects due to exposure and the way it is regulated.


Radiation has always been present and is all around us. Life has evolved in a world containing significant levels of ionizing radiation. We are also exposed to man-made radiation from sources such as medical treatments and activities involving radioactive material.


The health effects of radiation are well understood. Since the early 20th century, radiation’s effects have been studied in depth, in both the laboratory and among human populations. Because of the known health risks of radiation, it must be carefully used and strictly controlled. A balance must be struck between radiation’s societal benefits and the risks that radiation poses to people, health and the environment.


The Canadian Nuclear Safety Commission (CNSC) regulates the use of nuclear energy and materials to protect the health, safety and security of Canadians and the environment; and to implement Canada's international commitments on the peaceful use of nuclear energy. It also sets dose limits to prevent workers and the public from excessive radiation exposure.


This 3 PDH online course is applicable to safety engineers and professionals who are interested in learning more about nuclear safety.
Learning Objectives

This PE continuing education course is intended to provide you with the following specific knowledge and skills:

  • Understanding the definitions of atoms, isotopes and radioisotopes
  • Familiarizing with the types of radiation: non-ionizing and ionizing radiation
  • Knowing the natural and man-made sources of ionizing radiation
  • Understanding the health effects of radiation exposure and how it causes cancer
  • Familiarizing with the epidemiological evidence of the effect of the radiation exposure
  • Identifying the radiation dose limits and the typical radiation doses produced by natural and man-made sources
  • Learning the types of radiation doses: absorbed, equivalent and effective dose
  • Familiarizing with the rules regulating radiation
