Many countries around the world, including Canada, have recognized this problem and have taken steps to protect the ozone layer from more damage. Efforts have focused mainly on controlling the production and use of chemicals known to damage the ozone layer. These chemicals are used mainly in refrigeration and air-conditioning.

Canada has phased out the production of all ozone-depleting chemicals, and has taken steps to control their use through regulations that are part of the Canadian Environmental Protection Act.

The earth's ozone layer protects us from the sun's harmful UV rays. But over time, the release of certain chemicals into the environment has damaged the ozone layer. As the ozone layer thins, more UV reaches the earth's surface.

Infrared (IR) light is a type of electromagnetic radiation that lies between the visible end of the light spectrum, and the microwave spectrum (Vollmer and ...

The second layer of the image displays detailed information about the range of Ultraviolet radiation, Visible light, and Infrared radiation. They are displayed along a continuum beginning with the types of Ultraviolet light, continuing with Visible light, and ending with Infrared radiation.

Ultraviolet radiation is invisible energy in the wavelength range from 100 to 400 nanometers (nm). A nanometer is one billionth of a meter. UV radiation has a shorter wavelength and is more energetic than visible light. Depending on its wavelength, it can get through the ozone layer and affect our health in different ways. The shorter the wavelength, the more harmful the UV radiation. However, shorter wavelength UV radiation is less able to penetrate the skin.

In 1987, Canada was one of 24 nations to sign the Montreal Protocol on Substances that Deplete the Ozone Layer. This was the first international agreement to limit the use of ozone-depleting chemicals. Since that time, more than 70 countries have signed the Montreal Protocol.

Our machine lights have high protection ratings to provide reliable and safe lighting for machinery and production facilities.

Ultraviolet (UV) radiation comes from natural sources (like the sun), and artificial sources (like black lights, welding equipment, lasers, and tanning equipment).

The sun is a star roughly 150 million kilometres away from the earth. Without the sun, life on earth would not exist - our planet would be frozen and dark.

Health Canada's Consumer and Clinical Radiation Protection Bureau assesses, monitors, and helps reduce health and safety risks from radiation emitting devices and other sources of radiation, including tanning equipment.

The highest energy and shortest wavelength electromagnetic radiation is the Gamma Ray. The lowest energy and longest wavelength electromagnetic radiation is the Radiowave.

The top layer of the image showing electromagnetic radiation displays the rays in order of highest energy and shortest wavelength, through to lowest energy and longest wavelength.

A nuclear reaction at the sun's core creates massive amounts of radiation, or energy. This energy (also known as the electromagnetic spectrum) includes radiowaves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays.

After the display of the range of visible light, Infrared radiation is placed last along the continuum. Infrared radiation displayed as having a range from 725 nanometres to beyond 825 nanometres.

The Public Health Agency of Canada monitors cancer in Canada and develops programs to reduce cancer risks. Health Canada promotes public awareness about sun safety and the harmful effects of UV radiation.

Along the same continuum in the image, Visible light is displayed after the Ultraviolet radiation waves. Visible light is displayed as having a range from 375 nanometres to 725 nanometres.

Ultraviolet radiation is shown to have a range of types. The types of radiation are displayed from left to right in descending order as UVC rays, UVB rays and UVA rays.
