[ from memory, this may have little to do with the facts ] I don't have my references handy (standard disclaimer) but a study was done very recently at U of Waterloo. One of the things tested was the effect of the very low frequency radiation on the unborn fetus. The simulation used chicken eggs which were incubated in front of a CRT which was running (sorry, I don't know if there was a control group, I expect there was). There was a marked increase in abnormal chicks and non-births. In general our socienty treats electromagnetic radiation very carelessly. The effects of low frequency radiation have been discounted since the radiation is non-ionizing and hence `harmless'. Microwave radiation is also underestimated but has recently been shown to cause miscarriages in mice (at currently allowed doses). I personally feel that our disregard for the effects of EMR is similar to widespread use of lead in Roman times. It may eventually poison us and we'll never even know why. If anybody asks (via mail please) I will spend some time and dig up these articles. Kevin -- Kevin Szabo' watmath!wateng!ksbszabo (U of W VLSI Group, Waterloo, Ont, Canada)
