Does the CPU/tower emit harmful radiation?
Q: I work in my room and I have a computer tower about 40 cm from my bed on the right side of my head and on the left is a monitor about 80 cm away. When I go to sleep, I turn off my monitor but the computer tower remains on. Do I have to keep some minimum distance from my computer tower and the monitor? Does the computer tower emit radiation like a monitor?
A:The computer central processing unit (CPU/tower) does not primarily emit significant radio frequency or other waves. However, wireless Local Area Networks (LANs) work on radiofrequency waves and may, therefore be associated with cell damage. While scientific evidence is awaited on the potential effects of these networks, it would be worth considering switching the wireless connection off when not in use. Wired Internet service providers, including broadband, are safe and may be left on.
