Almost three months after the controversial cell phone radiation law was put on hold, the San Francisco Board of Supervisors is still actively addressing the issue through a new approach. They are considering amended legislation that would mandate retailers in the city to display informational notices on radiofrequency (RF) exposure and provide fact sheets to consumers upon request. This initiative, proposed by Supervisor John Avalos, received unanimous approval from the board’s City Operations and Neighborhood Services Committee.


  1. What is the purpose of the amended cell phone radiation law in San Francisco?
    The purpose of the amended legislation is to provide consumers with essential information about RF energy and ways to minimize exposure without making any specific claims about the dangers of cell phone use.

  2. What were some of the requirements of the original ordinance?
    The original ordinance would have mandated retailers to disclose the specific absorption rate (SAR) of each phone sold in their stores, making it the first law of its kind in the country.

  3. Why did the CTIA oppose the ordinance?
    The CTIA, representing the wireless industry, opposed the ordinance citing concerns about its constitutionality, potential misinformation to consumers, and infringement on retailers’ First Amendment rights.

  4. What stance did Ellen Marks from the Environmental Health Trust take regarding the amended legislation?
    Ellen Marks from the Environmental Health Trust supported the amended language, emphasizing the importance of informing consumers about the potential risks of long-term cell phone use.

  5. How did the CTIA respond to the amended legislation?
    The CTIA continued to oppose the ordinance, arguing that it imposes unnecessary burdens on retailers and creates a negative perception of cell phones that already comply with federal RF safety standards.

  6. What is the role of the San Francisco Department of the Environment in relation to the fact sheets for consumers?
    The San Francisco Department of the Environment will oversee the preparation and review of the fact sheets to ensure their accuracy and consistency, with retailers only required to provide them upon consumer request.

  7. When was the revised resolution passed by the San Francisco Board of Supervisors?
    The revised resolution was unanimously passed by the 11-member board on June 19.


The San Francisco Board of Supervisors is revisiting the cell phone radiation law by considering amended legislation that focuses on educating consumers about RF energy and safety measures without making definitive claims about the dangers of cell phone use. Despite opposition from industry groups like the CTIA, proponents of the law, such as the Environmental Health Trust, advocate for informing consumers about potential risks associated with prolonged cell phone use. The amended ordinance aims to provide consumers with the necessary information while ensuring retailers comply with regulations in a feasible manner. By passing the revised resolution, the board emphasizes the importance of transparency and consumer awareness in the use of cell phones.
