Abstract
Abstract The aim of the research is to study the effect of microwave Wi-Fi radiation on humans and plants. The paper investigates national standards for permissible exposure levels to microwave radiation, measures electric field intensity and justifies the point of view regarding the safe use of microwave technologies based on multiple plant cultivation experiments at different distances from a Wi-Fi router. The results demonstrate that the radiation of Wi-Fi routers significantly impairs the growth, development, yield and unexpected drought resistance of plants at short distances from the microwave source (up to 1 m to 2 m; –33 dBm to –43 dBm; >10 V/m). Slight effects are found up to about 4.5 m from a full-power home Wi-Fi router. As a result, suggestions are made for safe and balanced use of modern wireless technologies, which can complement occupational safety and health regulations.
Highlights
Microwaves are electromagnetic waves with a frequency of 0.3–1.0 GHz to 300 GHz and the corresponding wavelength from 1 m to 1 mm

Summary
Microwaves are electromagnetic waves with a frequency of 0.3–1.0 GHz to 300 GHz and the corresponding wavelength from 1 m (in some sources 0.3 m) to 1 mm. Microwaves can be considered the shortest radio waves; more often this range is distinguished separately. Microwaves ranging from 1.8 GHz to 2.45 GHz are most widely used, and frequencies of 3.6 GHz and higher are currently becoming topical. Common microwave technologies are as follows [2], [3]: a) IEEE 802.11/Wi-Fi: 2.45 GHz and 5.8 GHz (medium radiation); b) Bluetooth: 2.45 GHz (very low radiation); c) microwave oven: 2.45 GHz (very strong radiation); d) mobile communications: 0.45 GHz to 2.1 GHz (moderate low radiation); e) wireless sensor networks currently: 915 MHz and. It is common practice to follow the recommendations on tanning time in ultraviolet rays, infrared sauna procedures, and it is time to develop and incorporate recommendations for safe use of microwave radiation into occupational safety regulations
