 The question still is, what`s negligable ???
 The genetic mutation process is an probability based process. And
 on the other hand X-ray Radiation forced by acceleration of electrons
 with low voltage can also lead to SOME (of course `few`) high-energetic
 Photons. Since there aren`t any studies known to me about the risk
 I am very careful about that thing. 
 And even if the X-Ray Radiation wouldn`t be dangerous there still
 remains the (ordinary) electro-magnetic field problem. 
 For example: It isn`t allowed (in some states) to build a school
 under an high-voltage-cable. Or the problem mentioned in my
 first message about the mobile telephones. 
 
 I don`t want to frighten anyone here but I think that it`s really
 necessary to look for information about the problem cause brain
 cancer isn`t funny at all.
