Jet aircraft are one of the most disturbing sources of noise in our environment. People who live in communities near airports have become increasingly concerned about potential health effects from aircraft noise.

Cell phones, cell phone towers and antenna installations are used to enable the wireless communication needs of Canadians. Learn about the safety of cell phones, cell phone towers, antennas and 5G technology.

With more Canadians using Compact flourescent lamps (CFLs), some have begun to question their safety, including the level of UV emissions, the electric and magnetic fields (EMFs) they create, and the presence of mercury in the lamps.

Some people are concerned that daily exposure to electric and magnetic fields (EMFs) may cause health problems.

There is no safe way to tan. Health Canada recommends you do not use tanning equipment (like sunlamps or tanning beds). However, if you do, it is important to know the risks.

Hand-held lasers and laser pointers are popular in Canada. First introduced in the 1960s, lasers are now used in many ways in our everyday lives. Unfortunately, many people who use them don't know about their potential dangers. High powered hand-held lasers are considered a danger to human health...

Radiation is energy that comes from a source and travels through material or space. Every day, Canadians come in contact with radiation in both their living and work environments.

The Canadian Nuclear Safety Commission (CNSC), formerly the Atomic Energy Control Board (AECB), has legislative control of nuclear fuel cycle materials and man-made radionuclides. However, naturally occurring radioactive material (NORM) is exempt from CNSC jurisdiction except for the import,...

This guide covers basic information on the following: hazards associated with radiation emergencies, radiation health effects, radiation detection and measurement, protection of workers, and management of radiation emergencies in Canada.

This Safety Code has been prepared to provide specific guidance to large medical radiological facilities where diagnostic and interventional radiological procedures are routinely performed using radiographic, radioscopic or computed tomography equipment.

Industrial radiography to date is an established practice that provides benefits concurrent with radiation risks. The radiation protection objective, therefore, is to keep the risks as low as reasonably achievable (ALARA) while maximizing benefits.

Diagnostic X-ray imaging is an essential part of present day medical practice. However, mammographic X-ray procedures must be carefully managed, because X-radiation has the potential for damaging healthy cells and tissues, and great care must be taken to obtain optimal image quality for...

This Safety Code has been prepared to provide specific guidance to the dentist, dental hygienist, dental assistant and other support personnel concerned with safety procedures and equipment performance.

This document is one of a series of safety codes prepared by the Bureau of Radiation and Medical Devices to set out requirements for the safe use of radiation-emitting equipment.

This code is accompanied by the Technical Guide for Interpretation and Compliance Assessment of Health Canada's Radiofrequency Exposure Guidelines, to assist users in understanding and assessing the safety of electromagnetic exposures in working and living environments.

Radon is a radioactive gas that is found naturally throughout our environment. It is produced by the decay of uranium found in rocks and soil. Since radon is a gas, it can move freely through the soil enabling it to escape into the atmosphere or seep into buildings. Radon is invisible, odourless...

Health Canada's Radiation Protection Bureau leads the National Radon Program, which is committed to reducing radon-induced lung cancer risk in the public through research and promotion of radon testing and mitigation in homes and buildings.

This document is intended for persons and organizations carrying out radon measurements in buildings that have a high occupancy rate and/or residency period for members of the public and are, therefore, considered “dwellings” for the purposes of radon testing

This document is intended for persons and organizations carrying out radon testing in residential homes. The purpose of the testing is to evaluate radon levels in order to determine the need for remedial action to protect the occupants.

Every region in Canada has homes with elevated radon; make sure yours isn’t one of them. Radon is the #1 cause of lung cancer in non-smokers. Reducing radon in your home is straightforward.
