The "Moscow signal" epidemiological study, 40 years on

Abstract

Overview

Between 1953 and 1979, the USSR irradiated the United States embassy in Moscow with microwaves, sparking significant debates on the health impacts of non-ionizing radiation. This historical incident remains a crucial reference point in understanding electromagnetic field effects on human health.

Findings

• The International Agency for Research on Cancer (IARC) in 2011 labeled radiofrequency electromagnetic fields as potentially carcinogenic.
• Recent studies suggest a reclassification of these fields from "possibly carcinogenic" to "carcinogenic."
• The initial 1978 epidemiological study by Lilienfeld et al. found no significant mortality increases but highlighted other health concerns which remain unresolved.
• New statistical analyses provide more insights but do not fully resolve the health impact questions.

Conclusion

The case of the "Moscow signal" illustrates the complexities of assessing low-intensity microwave radiation's health impacts. Despite methodological limitations and incomplete data, the findings lean towards recognizing potential non-carcinogenic effects like electrohypersensitivity. Continued research is essential, particularly analogous studies such as recent incidents involving embassy personnel in Havana.
