Yes, but not from a laptop computer.
According to the electromagnetics expert Devra Davis, anything that gets electricity going will emit electromagnetic fields. “Radiation” is a word that usually means an alpha or beta particle, gamma-ray, or X-ray coming out of a machine or substance – and those can’t come out of your computer because radiation requires energy levels at least as high as those used by computers. The lower frequency EMFs emitted by your phone don’t have enough energy to break up cells the way UV sun rays do.
