Impact of high-voltage lines

What risks might mean high voltage, either in high or medium voltage lines, power transformers?

High and medium voltage electrical emit electromagnetic radiation, noxious, more or less, depending on their power and distance.

High voltage can also ionize particles suspended in the atmosphere, pollutants that can be harmful if breathed by living beings.

For example, particles of combustion fumes of vehicles in cities, or particles of insecticides and pesticides from farm fields sprayed.

These particles can be transported by wind, after ionized by high-voltage lines, going to be breathed at distances greater than those laid down as removal of the high-voltage lines.

If the power transformers offer protection against the risk of electrocution, this is not enough to be safe?

Are two different subjects, a risk of electrocution and the risk of electromagnetic radiation.

Radiation protection must be studied taking into account the existing radiation fields, because these are not eliminated by walls or doors, this is ask specific solutions.
