[EMERGING]Emerging
Classification published for radiofrequency electromagnetic fields
An international expert working group classified radiofrequency electromagnetic fields as possibly carcinogenic to humans (Group 2B), a classification the monograph describes as reflecting limited evidence.
How to read this
This library reports what studies found. An entry describes a study's design, its findings in its own terms, and its limits. Nothing here is a claim about what a Sage Co. home does, delivers, or prevents.
Last reviewed August 30, 2026.
What they studied
- An International Agency for Research on Cancer monograph produced by a working group reviewing published epidemiological, animal, and mechanistic studies of radiofrequency electromagnetic fields.
- The review covered occupational, environmental, and personal-device exposure sources.
- The working group applied IARC's standard evidence-classification framework.
What they found
- The working group classified radiofrequency electromagnetic fields in Group 2B, possibly carcinogenic to humans.
- The monograph characterizes the human epidemiological evidence as limited and the experimental animal evidence as limited.
- The monograph states that the classification reflects the strength of evidence for a hazard, not an estimate of risk at any particular exposure level.
What this study does not establish
- A hazard classification, not a dose–response assessment and not an exposure guideline.
- The evidence base is described by the working group itself as limited; later reviews by other bodies reach differing conclusions.
- Exposure sources reviewed are largely personal devices and transmitters, not residential wiring or fixed building systems.
- This entry reports the classification. It is not a statement about any building Sage Co. designs or constructs.
