Old-fashioned CRT screens can cause a noticeable “flicker” of images, which is a major cause of computer eye strain. Even if this flicker is imperceptible, it still can contribute to eye strain and fatigue during computer work.

No, but their older counterparts, Cathode Ray Tube (CRT) monitors, do give off a small amount of radiation. The streams of electrons hitting the phosphor in the screen produce X-rays, but these are way below harmful levels.

Cathode ray tubes literally would bathe the inside of the glass tube with electrons. When they hit the front glass, they caused the material to fluoresce, releasing colored light visible on the front of the glass. A byproduct of all this electrical charge inside, was static electricity on the outside.
Do CRT TVs emit radiation?

No, but their older counterparts, Cathode Ray Tube (CRT) monitors, do give off a small amount of radiation. Coils in the monitor also emit some electromagnetic radiation.
Does a computer emit radiation when turned off?
Laptops can emit an EMF (electromagnetic field) radiation level of up to 150mG (milliGauss). Especially when your laptop is turned on and charging, the EMF is significantly higher than when it is turned off and unplugged.
Which is better CRT or LED?
