Is Wi-Fi dangerous?




Is Wi-Fi dangerous?

It seems that some of the public are still concerned that the radiation produced by Wi-Fi signals may be dangerous to our health.  Perhaps some straight forward data from researchers and a governmental health department can dispel this myth. The unwarranted concerns over Wi-Fi are another example of internet spawned fear mongering from the uninformed.

According to Health Canada and other international regulators there is no known health risk from the low frequency radio waves that are produced by Wi-Fi signals. Health Canada notes that the radiation produced by Wi-Fi in all publicly accessible areas are well below the exposure limits and no precautionary measures are necessary. “The limits specified in the guidelines are based on an ongoing review of thousands of published scientific studies on the health impacts of RF energy.” A number of these studies are available at the Health Canada and the World Health Organization websites.

Although no known link to low level radio frequency energy and human cancers has been identified through extensive scientific research, health regulators such as Health Canada, the World Health Organization and the International Agency for Research on Cancer (IARC) will continue to monitor research in this area and update any guidelines as necessary.

Top 10 globally relevant science books for non-scientists


By Kristin Tangen-Steffins

Technical language used by scientists can make current research and ethical issues difficult for the non-scientist to digest. Here is a list of interesting, informative and entertaining books written on a wide range of pertinent issues. Topics include basic biotechnology references, current technologies, dangers of human progress, resolution of misguiding historical information, the failure of humanity and the socio-economic impacts of major plagues.


The common thread is that all of these issues are relevant on a global scale. Our world is becoming smaller by means of digital communication. If more people become versed in significant global issues, there is a greater chance we can work together to overcome dangers to humanity, our environment and perhaps learn from our mistakes. Shared knowledge leads to increased collaboration, tolerance and positive solutions.
