If we wanted to implement stricter standards for mobile devices... If we were to establish a safety level of half of the current 1.6 watts per kilogram, there would be one problem: we would need special devices made only for Canada. Indeed, Canada would be the only country in the world to have such strict standards, much stricter than other countries. Mobile phone manufacturers, such as Nokia and Ericsson, would have to manufacture devices specifically for Canada and no other country, which would make the cost of these phones prohibitive.
As you know, companies make phones for billions of users all over the world. These suppliers would have to make special phones just for Canada, and they would be less powerful.
