Electrostatics

1.   The problem of static cling can be a real nuisance. One possible solution is to do what the electonic service guys do when handling equipment such as mobile phones and connect a wire to the GROUND or earth the surface you want free of static electricity.

The other technique you could use is to apply some CONDUCTIVE chemicals that manufacturers deliberately use to reduce the effect of static electricity on their plastics.

Alternately make the surfaces large so that the charge is distributed widely so that the charges cannot develop throughout the surface easliy.

2.   The reason why you're feeling a shock is not because of the electromagnetic radiation but becasue of what's called STATIC ELECTRICITY. To explain this briefly to you, as you may be aware the TV works by 'spraying' a stream of electrons on to the front of your monitor using what's called an 'electron gun' These electros scan across your screen several thousand times per second which gives you the sensation of an image by what's called 'persistence of vision. Actually these electrons emit visible light when they hit the phosphors colored red, blue and green. In fact three 'electron guns' work together to give us the typical color vision.

Some of these electrons just decide to remain on glass and give it a net negative charge. When you brush your hand across the front it is these electrons which are trying to jump into your hand that gives you this sensation of feeling a wave or a shock. That's why some monitors have an earth connection in the front to prevent this static.

Coming to your original problem of measuring the EMR (electromagnetic radiation) on your computer monitor it is not going to be easy. I tried this in fact some years ago as part of a project and you can find some more information about it by clicking on my FAQs and looking for Ultraviolet radiation (UV).

There is not only UV but also the visible that you and I are seeing. The visible is easy to measure with a light sensitive meter using a probe, but the UV is not directly measurable. That's why I was trying to use some fluorescene sodium that I had access to convert the UV to visible light just like the TV monitor does with electrons or a fluorescent light does with the UV at homes and our workplaces.

May be if I had spend some thousand dollars or more buying a sensitive UV meter, it MAY have made a difference but one can't be too sure. Scientists have definitely confirmed to us that TV and computer monitors are a source of UV and that can be hazardous along with the x-rays they emit too.
