The Ministry of Health recently expressed that novel industries such as IT have replaced traditional industries and become the new high incidence areas of occupational diseases. Electromagnetic radiation has become a new hazard factor for occupational diseases. Facing electromagnetic radiation, people cannot hide from microwave ovens, computers, televisions, air conditioners, mobile phones...and more. Electromagnetic radiation threatens the human reproductive system, immune system, and cardiovascular system. However, Associate Professor Chen Zhiliaiof the Obstetrics Department at the South Campus of Sun Yat-sen University’s Second Affiliated Hospital pointed out that although electromagnetic radiation is harmful, there is currently no medical evidence proving that it indeed causes pathological damage. Therefore, while those in the IT industry and white collars should pay attention to protection, they need not be unduly alarmed.
