My laptop is always sitting in my lap and I%26#039;ve begun to worry about the effect of radiation on my stomach/ovary area. Have I harmed myself by putting my laptop in my lap?|||Laptops don%26#039;t have radiation.|||I%26#039;ve never heard of this, but you may have something. Cell phones, microwave and the tv supposedly cause cancer.|||I have not heard that. However my computer professor told us that men have a decreased sperm count from a laptop on the lap.|||I wouldn%26#039;t think so. Your laptop does not emit any kind of energy (other than heat energy) that could cause this kind of damage in your cells. I think you are just fine. As for lowered sperm count in men as one other poster suggested, it is from the heat that they produce. Those things get HOT!

Ugh. Another edit. As for one posters comment on %26quot;optical radiation%26quot;. Um, that%26#039;s not a real thing.

Laurel F%26#039;s answer is really good, and informative.|||I wouldn%26#039;t put it there. I recently saw a segment on the nightly news, that men can get testicular cancer from doing so.|||The lap top gives off optical radiation from the screen which would affect your eyes. But in reverse it gives off magnetic radiation which can actually reduce your chances of cancer according to some doctors magnetic radiation is a form of treatment for some cancers. But you can also ask a doctor who would know a little more about this than me. Preferably an OB-GYN.|||First, I would be far more concerned about your cell phone—get an earpiece!

If you are that worried, do what I did…go to Target and spend $15 on a lap desk which will keep if off of your skin.

Also…you can really screw up your laptop if the vents get blocked which happens a lot on the couch, bed, etc., with soft fabrics moving around. A lap desk will create a hard, even surface which allows for ventilation.|||The laptop doesn%26#039;t produce enough radiation to cause cancer. It%26#039;s not the additive effects of radiation that really matter but the magnitude of dose received as a single exposure. Hope it answers your question.
