Does Computer Radiation Cause Cancer?
Computer radiation belongs to non-ionizing radiation and generally does not cause cancer. From a physics perspective, radiation refers to the energy produced by electromagnetic wave frequencies, which is transmitted in the form of waves or subatomic particles through a vacuum or medium. Based on the frequency and wavelength of electromagnetic waves, radiation is classified into two types: ionizing radiation and non-ionizing radiation.
Ionizing radiation can cause the separation of atoms and molecules in matter, damaging human cells and potentially causing cancer, such as X-rays, beta rays, and gamma rays. Non-ionizing radiation, however, has relatively longer wavelengths, lower frequencies, and lower energies. It generally does not harm cells or damage DNA within cells, thus is not likely to cause cancer. The radiation emitted by computers, mobile phones, radars, and televisions falls into the category of non-ionizing radiation.
Research indicates that the public's exposure to extremely low-frequency electric field levels and non-ionizing radiation poses no practical health risks. Although radiation from computers does not cause cancer, prolonged sitting in front of a computer screen can cause other physical harm, such as vision loss, muscle strain, and lumbar disc herniation. It is recommended to control computer usage time, standing up and engaging in appropriate activities every 30 to 40 minutes. Additionally, it is important to develop good lifestyle habits, such as regular exercise, correcting poor posture, and maintaining a balanced diet.
