I have professional qualifications. I know not to peer into an active waveguide or close to a transmitting microwave dish of a satellite uplink. You'd eventually get a cataract or two.
A phone can use a similar band to Wifi (not the same bands unless in WiFi mode) and is about x5 the power (variable), but about x20 closer.
But the phone power effective on your face isn't multiplied by 20, but by 400 (inverse square law), so the effective power is 5 x 400 = 2000 times more than the wifi on a Kobo.
There is no cancer risk. The risk on these bands is a cataract if the power was a lot higher.
A microwave oven is about 800 times to 3000 times the power of a mobile phone, but is is pulsed about 20 times higher still as it uses a magnetron.
There are a lot of lies about phones, wifi and mobile/cell on the Internet.
