to reduce the power of radiation from the monitor. But what to do with
other parts of the monitor, as well as the system unit? All of them too
are sources of radiation.

as! Moreover, the laptops are closest to the human body,
which clearly does not reduce the degree of danger.

narcotic. It may appear in an adult, but more often
children suffer. Closure, lack of interests and friends in
