10GHz+ a problem for ES people?

Just wonder if high radio frequencies really are a problem for ES people? Like 10 GHz and over? Are there appliances around us that emits troublesome frequencies in that high area?

Apparently. Maybe they're not used in everyday appliances but radars usually operate at radio frequencies (RF) between 300 MHz and 15 GHz. More and more cars are being equipped with radar sensing devices as well.
