living near high voltage powers' health issues

[fresh]

There are lines of high voltage powers standing in the middle of a park which is under construction . I don't understand why local government permits it ?? 

Besides park, there are around hundreds of thousands of people living near by. 

Is living near high voltage power a threat to people's health ?

I did some research.

this one is horrible.

https://hps.org/hpspublications/articles/powerlines.html

this one is controversial. 

which one is right ? who can give me a latest scientific answer ?

thanks !

Go with the latter because he's supporting what he's saying with expert references. The other guy is just hand waving and magnifying any risk into a tangible one that one should be seriously concerned about.

how about the last one. 

Professor Henshaw, a physicist with the University of Bristol, found that if a person spent 10 per cent of his time close to power lines, he would be subjected to up to twice the acceptable level of radioactivity. His study linked power lines to leukaemia. Henshaw says they also cause skin cancer, lung cancer, depression and increased incidents of suicide.

In other research carried out at Oxford University, it was discovered that children who had lived within 200m of high voltage lines at birth had a 70% higher risk of leukaemia than those 600 meters or more away.

  Although this is an old article it illustrates how easily one researcher can derail the understanding and feed the hysteria of a "possible" public health issue. All follow up research appears to contradict the original claims. This was a pretty big deal at the time because it lead to expensive changes in the routing of high tension power lines that were ultimately paid for by the rate payers.

 

[John Cuthber]

"Some large studies, including a large study in the United States, have failed to find any link between living near power lines and developing any sickness or diseases, such as cancer. A 1997 study found that it did not matter how close one was to a power line or a sub-station, there was no increased risk of cancer or illness."

How is radioactivity involved?

There was a summary in the New Yorker maybe 25 years ago. Yes, illnesses are greater near power lines. But, what was later found was that when you adjust for poverty levels (living there has a strong correlation with low income) the correlation vanishes. Being poor is associated with a lot of health issues.

The original research speculation was that the emf fields concentrated the naturally occurring radon that accumulates in enclosed spaces sufficient to increase the likelihood of cancers.

Quote

...He and his team have discovered that the mains leads to ordinary domestic electrical appliances, such as microwave ovens and hairdriers, are able to attract the radioactive products of radon present in air within rooms. However, Henshaw does not believe this effect results in health problems because it occurs only very close to the leads. What concerns him much more are results from another piece of research - the evidence that the same harmful concentrations of radon products may be present around overhead power lines. The electromagnetic fields around power lines have the ability to concentrate radon, and may also concentrate other harmful substances into a potent cocktail of carcinogens.  https://www.timeshighereducation.com/news/death-in-the-air/92992.article

I can see how a high voltage cable could attract dust carrying radon daughters.
I can't see how it's meant to attract an inert gas.
It's either BS or poor reporting (or both).

It does say 'radioactive products of radon' in my quote. It's me remembering wrong in my posted comment. I wrote my post from memory which was slightly in error, then I found the article link and edited it in without correcting my comment.

 radon daughters ( i googled it)

"ions that are decay products of radon. They are regarded as a potential health hazard by the U.S. Environmental Protection Agency because they tend to adhere to surfaces, such as the alveoli of the lungs, where they can cause ionizing radiation damage."

I didn't get the reliable answers of how far away from high voltage powers is safe...

is this website reliable ?
