Radiofrequency Safety Standards

Mobile communications devices such as smartphones have become much more pervasive over the last decade. Misinformation has continued to circulate, however, about the safety of exposure to wireless technology. Unfortunately, many of these misconceptions are based on previously-debunked myths about radiofrequency (RF) energy.

In reality, the RF energy that mobile devices emit is both strictly regulated and hundreds of times below the limit at which health effects could occur. To make it easier for Canadians to access such up-to-date information on the topic, the Canadian Wireless Telecommunications Association (CWTA) has put together the following summary of facts about RF exposure, as well as the findings that government agencies and international bodies have reported to date.

 

Radiofrequency (RF) energy and wireless communications

Electromagnetic energy (EME) refers to the different kinds of energy released into space. Some EME, like energy released from the Sun and other stars, lightening, and the Earth’s magnetic field, is naturally occurring, while other types of EME, such as radar, TVs, mobile phones, microwaves and x-rays, is generated by human-made sources.

Radiofrequency (RF) energy is the form of EME used in communications technologies like television, radio and mobile phones. It has been used for more than 100 years beginning with the introduction of broadcast radio.

Are RF energy and wireless communications safe?

The potential health effects of RF energy used for mobile phones and other wireless services has been studied for decades. Research by Health Canada and international bodies including the World Health Organization has produced no substantiated evidence of harmful effects from RF technologies used within existing safety standards. There is consequently no basis for finding that mobile wireless communications poses a health hazard to the Canadian public.

Is 5G Safe?

5G or “fifth generation” refers to the next generation of mobile wireless standards and technologies. The advanced capabilities of 5G will result in even faster mobile data speeds, enable innovative new products and services, and help connect more Canadians to the internet. But as with the introduction of other new technologies, 5G can be the subject of misunderstanding and, in some cases, deliberate misinformation. Contrary to this misinformation, there are no established health risks from the radiofrequency waves used in 5G networks in accordance with applicable safety standards.

How does the Government of Canada ensure your safety?

Canada’s approach to RF safety is among the most stringent in the world. Health Canada has established guidelines for safe exposure to RF energy, known as Safety Code 6 (SC6), which utilizes very conservative limits set at least 50 times below the threshold of any potential adverse health effects.

Innovation, Science and Economic Development Canada (ISED) uses Safety Code 6 in setting its standards and regulations for RF exposure limits for wireless devices and associated infrastructure, such as antennas. All wireless devices must meet ISED’s requirements and be certified before being sold in Canada. Antenna installations must also meet ISED’s requirements at all times as a condition of a carrier’s license.

Canada’s mobile network operators consistently monitor their networks, and ISED audits wireless devices and antenna installations to ensure compliance with safety standards.

Are Canada’s RF safety standards similar to those in other countries?

Canada’s science-based safety standards are consistent with the safety standards used in other parts of the world, including the United States, the European Union, Japan, Australia and New Zealand.

If RF energy is safe, why is there a need for safety standards?

RF energy is non-ionizing, meaning it does not affect the chemical bonds between cells and tissue. However, at high levels of exposure, RF energy can cause heating of the body. For this reason, governments set exposure limits. In Canada, those limits are at least 50 times below the level at which heating caused by RF energy is known to have an observed effect.

How can I limit my wireless RF exposure?

Health Canada does not call for taking specific steps to avoid RF from wireless networks, as exposure levels in Canada are far below the safety limits set by the federal government. Individuals may choose to limit their personal exposure to wireless RF, however, by shortening the length of wireless phone calls; substituting calls with text messages; or using accessories such as headsets, speakerphones or earpieces to increase the distance between a user and the device.

Canadians can also check the SAR rating (an indication of the amount of RF energy that the device emits) for specific mobile products. SAR ratings can be found using the Innovation Canada Radio Equipment List page and searching for the alphanumeric Certification Number printed on each device. (SAR values may not always represent the exact amount of RF energy absorbed during everyday use, since they are based on the energy that a device emits when on its highest power setting.)
