The city council of Mill Valley, CA, a wealthy city north of San Francisco, voted unanimously to effectively halt installation of new small cell towers to accommodate 5G technology over health concerns. The "urgency ordinance" will bar applications for 5G towers while the city drafts a more permanent rule.
The city council had received 145 pieces of mail concerned about negative health impacts, reports TechCrunch, compared to just five letters in support of small cells. The concern is over the impacts of exposure to electromagnetic fields, although the small cell antennas for 5G emit less radiation than those used for 4G.
With the vote, Mill Valley became the third community in Marin County to pass a similar ordinance, following San Anselmo and Ross.
The health concerns about 5G are exacerbated because the service will require more small cells placed throughout cities, closer to residents than have been necessary for other wireless technologies. Critics have said that the radiation could cause increased risk of cancer, fatigue, headaches and other effects, although research has been inconclusive (that has not stopped the California Department of Public Health from issuing controversial warnings about the health effects of personal cell phones). The National Cancer Institute summed up the field by saying a "limited number of studies" showed evidence of a "statistical association of cell phone use and brain tumor risks," but added that "most studies have found no association."
