Let's Talk Tritium

Consultation has concluded

Let's Talk Tritium is now closed. Thank you to everyone who submitted questions.

Have you heard of tritium? Tritium is a rare isotope of hydrogen, and the only radioactive form of this widespread natural element. The Canadian Nuclear Safety Commission (CNSC) regulates tritium releases into the environment to protect you and your community and wants to hear from you.

Worried about exposure to tritium?

Wondering about potential uses of tritium?

Send the CNSC your questions and its experts will answer them here.


Background on tritium

Cosmic rays produce tritium when they interact with gases in the upper atmosphere. In Canada, tritium is a by-product created by nuclear reactors and tritium processing facilities.

Tritium has several industrial uses, including glow-in-the-dark lighting, like in exit signs or airport runway lights, and as a biomedical tracer in research.

CNSC experts study the environmental behaviour and health effects of tritium in collaboration with national and international partners.

The CNSC recently updated its tritium resources to provide more information on this important isotope.
