No, electrical wires located below the window of your office do not pose a significant danger or emit harmful radiation. The electromagnetic fields generated by standard electrical wiring used in buildings, such as power cables and electrical wires, are generally considered to be safe and have negligible health effects on humans.
The levels of electromagnetic fields produced by typical household or office electrical wiring are generally low and diminish rapidly with distance. The intensity of electromagnetic fields decreases significantly as you move away from the source, such as electrical wires. Therefore, the electromagnetic fields generated by the electrical wires below your office window would likely be very weak by the time they reach your office space.
In many countries, there are regulations and safety standards in place to ensure that electrical wiring installations comply with electromagnetic field exposure limits that are deemed safe for humans. These standards aim to minimize any potential health risks associated with exposure to electromagnetic fields.
However, it's worth noting that if you have concerns about electromagnetic fields or any other potential health risks related to your workplace, it's a good idea to consult with occupational health and safety experts or relevant authorities who can provide specific guidance based on your location and circumstances.
