Radiation caused by WiFi smartphone s etc.?

I’m 15 years old. Just had WiFi extended fitted outside my bedroom wall because we can’t get signal upstairs. I feel like there might been tooo much radiation and I want to know ways I can prevent myself. I can’t turn the WiFi off as my parents will find out so other than being in the garden is there any other ways... show more I’m 15 years old.

I can’t turn the WiFi off as my parents will find out so other than being in the garden is there any other ways I can protect myself. Also I own a phone, iPad and laptop and microwave so already get a bit of radiation. I’m really scared. I’ve already chose wired headphones over wireless, what Adele’s can I do?
