Health Implications of Frequencies Used in SpaceX’s Sat-To-Cell Starlink Service

SpaceX’s Starlink service, a pioneering satellite-to-cellular communication system, brings into focus the use of specific radio frequency (RF) bands, particularly the 1910-1915 MHz and 1990-1995 MHz ranges.

Intriguingly, these frequency bands encompass the 1947.47 MHz and 1977 MHz frequencies, which have been scrutinized in scientific studies for potential health impacts.

What are the implications of Starlink’s use of these frequencies for cell-to-sat service?  Drawing a parallel with existing research has raised concerns about the biological effects associated with similar RF ranges. We will delve into SpaceX’s technological leap with the cautionary findings of these studies, examining the balance between innovation and health safety in an increasingly connected world.

Overview of the Study on UMTS Frequencies:

A recent scientific inquiry into the biological effects of radiofrequency radiation has brought to light findings that are critical in the context of emerging telecommunications technologies like SpaceX’s Starlink. A notable study focused on the genotoxic effects of Universal Mobile Telecommunications System (UMTS) signals, specifically at the frequencies of 1923, 1947.47, and 1977 MHz.

This study revealed significant concerns, particularly an observed induction of DNA damage at the 1977 MHz frequency. Such findings are pivotal as they suggest potential health risks associated with RF radiation at levels and frequencies similar to those used in modern cellular communication systems.  The study’s relevance is amplified in light of SpaceX’s Starlink service utilizing adjacent frequency bands, raising crucial questions about the safety of these technological advancements of putting cell phones in space.

Starlink’s Frequency Range and Health Concerns:

As SpaceX’s Starlink gears up to utilize frequency ranges that include 1947.47 MHz and 1977 MHz, there is growing concern about the potential health implications. These frequencies, as highlighted in previous scientific studies, have been associated with DNA damage in human lymphocytes. This correlation raises significant questions about the broader health implications of continuous exposure to these RF frequencies. This section will explore how the frequencies used by Starlink overlap with those examined in the study, and what this overlap might mean for public health, especially considering the global scale of Starlink’s deployment. The examination of these frequencies within the Starlink context underscores the importance of a cautious approach to the deployment of satellite-based cellular services.

 Regulatory Considerations and Public Health:

The deployment of SpaceX’s Starlink system, using frequencies near those implicated in health risks, brings regulatory considerations into sharp focus. This section will discuss the role of regulatory bodies like the Federal Communications Commission (FCC) in overseeing telecommunications advancements while safeguarding public health. We’ll delve into the process of how such technologies are evaluated for health impacts, the existing guidelines for RF exposure, and the potential need for these standards to be revisited in light of new research findings. The section aims to highlight the balance that regulators must strike between fostering technological innovation and ensuring public safety, particularly when confronted with emerging evidence of health risks associated with certain RF frequencies.

The Need for Further Research and Precaution:

Given the potential overlap of Starlink’s frequencies with those shown to cause DNA damage in scientific studies, there is an urgent need for further research and precautionary measures. This section will address the necessity for ongoing, independent studies to better understand the long-term health impacts of exposure to these specific RF frequencies. It will also explore the concept of the precautionary principle in public health policy, advocating for cautious implementation of new technologies until their safety can be more conclusively established. The aim is to underscore the importance of a proactive approach in safeguarding public health in the face of technological advancements that utilize frequencies with known health concerns.


In conclusion, the deployment of SpaceX’s Starlink service using frequencies close to those shown in studies to have potential health risks necessitates a careful and informed approach. While technological advancements like Starlink promise significant benefits, including global connectivity, they also bring challenges in ensuring public health safety. This blog has highlighted the need for rigorous scientific research, stringent regulatory oversight, and the application of precautionary principles in the face of emerging evidence of potential health risks associated with specific RF frequencies. As we embrace the possibilities of advanced telecommunications, it remains paramount to prioritize the well-being of communities and the environment, ensuring that progress does not come at the expense of public health.

The study you are referring to is titled “Effects of different mobile phone UMTS signals on DNA, apoptosis and oxidative stress in human lymphocytes.” The authors of this study include Sachin Gulati, Pavol Kosik, Matus Durdik, Milan Skorvaga, Lukas Jakl, Eva Markova, and Igor Belyaev. This study investigated the genotoxic effects of UMTS signals at frequencies used by 3G mobile phones, specifically focusing on 1923, 1947.47, and 1977 MHz. It was published in the journal Environmental Pollution. For a detailed overview of the study, you can refer to the publication or its abstract available online.


Incorporating the findings from the Ramazzini Institute (RI) study alongside those of the National Toxicology Program (NTP), Schwarz et al., and Gulati et al., enriches our understanding of the potential health effects of radiofrequency electromagnetic fields (RF-EMF) used in mobile communications. The RI study is particularly valuable because it independently confirmed several key findings of the NTP study, lending further credibility to the observed effects.

Key Points of the RI Study:

  1. Confirmation of NTP Findings: The RI study corroborated several significant results from the NTP study, particularly regarding the carcinogenic potential of RF-EMF. By replicating these findings in a different experimental setup, the RI study reinforces the likelihood that RF-EMF exposure can lead to cancer and other health issues in certain contexts.
  2. Large-scale, Lifelong Exposure Analysis: The RI study is notable for its examination of the effects of lifelong exposure to RF-EMF at levels comparable to those encountered in the environment. This approach provides valuable insights into the potential long-term health impacts of RF-EMF exposure in real-world settings.
  3. Tumor Incidence in Specific Cell Types: Similar to the NTP study, the RI study observed an increased incidence of tumors in specific cell types following RF-EMF exposure. This finding adds to the evidence suggesting that certain cell types are more susceptible to the effects of RF-EMF.

Combined Implications of All Studies:

  • Consistent Evidence of Health Risks: The collective findings from these studies present a consistent picture of potential health risks associated with RF-EMF exposure. The fact that both the NTP and RI studies observed similar effects lends significant weight to concerns about the safety of current levels of RF-EMF exposure.
  • Need for Re-evaluation of Safety Standards: The converging evidence from these diverse studies indicates that existing safety standards and guidelines for RF-EMF exposure may need to be reassessed. Current standards might not fully account for the observed cell type specificity, frequency dependency, and potential long-term effects.
  • Importance of Ongoing Research: Given the complexity and variability of the effects observed in these studies, there is a clear need for ongoing research. Future studies should aim to further elucidate the mechanisms underlying these effects and to determine the full spectrum of potential health risks associated with RF-EMF exposure.

In summary, the inclusion of the RI study’s findings alongside those of the NTP, Schwarz et al., and Gulati et al. provides a more robust and comprehensive understanding of the potential health effects of RF-EMF exposure. It underscores the importance of considering a wide range of frequencies, cell types, and exposure durations in evaluating the safety of RF-EMF emissions from mobile communications and other sources.
