What kind of radiation does a CRT/TV monitor emit?
As for cell phones,
There is no issue, unless you happen to have a 400W cell phone (like some hams have, K band)
Cell phones are 0.6watts to 3watts, you are mostly water, water can dissipate far more heat then this (you start to get problems if you have a genetic abnormality/ you deal with KW magnitrons
That and they are microwaves, and thus do not have enough energy to damage anything (they are non-ionising and therefor the only risk is of heating)
(sorry but you just had to be set strait with the facts)
