Ask HN: What's the current consensus on Wifi and safety for humans?

Every once in a while, the issue of Wifi and other EMF comes up. As someone with small kids, I revisit this every once in a while.

It's practically impossible to isolate one's environment now, especially if living in an urban centre.

A quick search of Pubmed:

(1) Environmental Radiofrequency Electromagnetic Fields Exposure at Home, Mobile and Cordless Phone Use, and Sleep Problems in 7-Year-Old Children. (2) Modeled and Perceived Exposure to Radiofrequency Electromagnetic Fields From Mobile-Phone Base Stations and the Development of Symptoms Over Time in a General Population Cohort. (3) Mobile phone radiation causes brain tumors and should be classified as a probable human carcinogen (2A) (review). (4) Outdoor and indoor sources of residential radiofrequency electromagnetic fields, personal cell phone and cordless phone use, and cognitive function in 5-6 years old children.

Any subject matter experts here who can provide an update on this topic?
