WiFi emitters produce electromagnetic radiation  Five middle school students in Denmark nurtured the seeds of water celery in rooms with and without WiFi emitters  After 12 days, they found that the germination rate of seeds in the room without WiFi emitters was 95 4%, and that the germination rate of seeds in the room with WiFi emitters was 85 3%  As a result, many people worry that the radiation of WiFi will affect the health of the human body
However, many experts believe that the above experiments are not rigorous, and it can not be concluded that the radiation of WiFi is harmful to the human body based on the experiment
Other conditions should be kept unchanged in the same room, and the experiment should be repeated with and without WiFi emitters.
