Title: 5G Wireless Communication and Health Effects-A Pragmatic Review Based on Available Studies Regarding 6 to 100 GHz

Authors: Myrtill Simkó; Mats-Olof Mattsson

Author: Simkó et al.

Date: 2019-09-13

Kind: Narrative review

Why: Before treating a new frequency band as understood, it helps to see how much biological research exists and what it actually tested.

Scope: A structured pragmatic review of 94 in-vivo and in-vitro publications at 6–100 GHz, with studies concentrated around 30–65 GHz.

Summary: The authors report responses in 80% of animal and 58% of cell investigations. They highlight skin and eye heating questions, sparse coverage in some frequency bands and environmental research needs.

Limitations: Those percentages count reported biological responses, not harmful outcomes or independent replications. Study quality and temperature controls were often insufficient, and the review cannot establish non-thermal harm or a meaningful overall safety verdict for 5G.

Topics: 5G research gaps; Skin and eyes; Exposure assessment

Exposures: Millimetre waves; 6–100 GHz; 5G-related bands
