Yes, I would.
The question was about high-voltage transmission lines. For that, we're not interested in power density. We're not talking about microwave energy; we're talking about extremely low-frequency electric and magnetic fields. Canada's guideline on that is about 833 milligauss—that's the strength of the magnetic field. Studies are showing that there's an increased risk of childhood leukemia between two and four milligauss; an increase in breast cancer up to 12 milligauss; and an increase in miscarriages at 16 milligauss. All of these values are well below the 833 milligauss that Health Canada uses for magnetic fields.
So there is a concern about people who live near them. The childhood leukemia has been recognized internationally. Low-frequency magnetic fields have been classified as a class 2B carcinogen, meaning a possible carcinogen.
