What is radiation?

Radiation is the transfer of energy from a radioactive source, by way of electromagnetic waves or fast-moving subatomic particles. There are several types of radiation, each with different effects – and requiring different levels of containment.

Quantifying radiation

Radiation is measured essentially in two ways: by the amount of energy conveyed from a radioactive source, and by the effect of that radiation on atoms and molecules. These two sets of measurements allow regulators to set standards for personal and environmental safety.

Effects on the body

Radiation at high doses can damage living tissues, principally through burns or damage to DNA. However, radiation has always been a part of our environment, and the levels that we are routinely exposed to are far below levels shown to carry any risk.

Radiation regulations

Canada’s nuclear industry is proud to have one of the top global nuclear regulators ensuring public and environmental safety. The Canadian Nuclear Safety Commission is a leader in comprehensive radiation protection, and not only keeps Canada safe, but also acts as a benchmark for other countries.
