What are power lines?

A power line is a cable that carries electricity from a power station to the users of the electricity or between electric utilities in a network. The cables are passed from a tall steel lattice structure. Power lines are located high overhead or buried underground. So they do not get in the way of any human activity or are a threat to any wildlife. The wires are spread to prevent birds on perching on them and electrocuting themselves although all wires are surrounded by a layer of thick plastic as plastic is not a conductor of electricity.

About power lines

The power line frequency is extremely low as you can see from the diagram below

Conclusion

From the section ‘about power lines’ you can see that power lines produce a very low radiation, lower than radio. Hence do not damage people’s health dramatically. They produce a very low frequency so affect the human body little. There must be another factor causing diseases which hasn’t yet been discovered fully.

    This increases the likelihood of the patient receiving a significant radiation dose in parts of the body some distance away from the part being exposed intentionally. It also increases the chance of scattered radiation escaping from the patient - a potential hazard to hospital staff in the vicinity.
