I will ask my brother tomorrow, he used to climb them along with transmission towers in Aussie.
He told me once that a TV transmitting tower gives off more radiation than a power or cell tower, but will double check with him tomorrow

When you climb an AM radio tower, you either have to power it down, or wear an RF Armour suit which is the same theory as the faraday suit pictured back up the thread, but the modern versions look just like a thickr version of a HAZMAT suit. It is easy for a piece of paper to catch fire when you are only a couple of metres away from the antenna, or someone to get burnt. As you move away from the antenna (like 10-20 metres, it becomes very safe) Some FM towers in the states are like this also where they broadcast in very rural areas with several kilowatts of power.

I dont know if we have any kordia engineers here but they would probably tell you they have to power down certain transmitters before they are allowed onto certain levels of a transmission tower.

The house creeking is normal at night and in the morning. We used to live in a wooden house when i was a child and i can remember not being able to sleep because the house was cooling down at night and warming up during the day.
The best way i can describe it is a rock dropping onto a sheet of corrogated iron, without any bouncing or resonating. Just makes the sound randomly every so often for a few hours each evening and morning.
Or possibly also could be described as someone standing on an upper floor in the roof, very slowly putting their weight onto a floorboard prolonging a single creeking sound out over a couple of hours.

Now i am probably starting to sound like i have smoked too much of the bad stuff.

If any of you live in the Henderson, Massey area in Auckland, is that big red and white tower a transmission tower? At night it has red lights shinning. It doesn't look like a radio tower because i can't see any major antennas. I go past it and am still battling with that!

Tell us where it is by looking it up on google earth and giving us gps coordinates, or google maps with a street number (zoom right in to see street numbers) and we can look it up in the RSM database for you.

Would I buy a house under or near a powerline? No ways. Its not a proven hazard but its one of those things I would not tempt. Do some reasearch on magnetic fields and then come to your own conclution.

Besides the health risks. You have extremely high voltage wires running directly above your bedroom. Should something go wrong and one of those cables come loose and fall on your house, well there is probably no health risk there either.

Here it is.. How to find coordinates in Google maps?? but the photo is from google maps using street view opposite 366 Triangle Road, Massey, Auckland.

It is location ID 10071 in the RSM database at http://www.rsm.govt.nz/smart-web/smart/page/-smart/domain/licence/SelectLicencePage.wdk?fromHome=Yes

10071 registers 5 AM radio stations for Radio Network Ltd, Radioworks, A chinese station, maori station, and the NZ racing board.

Radio Network and Radioworks are the big national networks like Newstalk ZB and Radio Live - all the brandname stations

I used to work around those towers in the 1970s. They are definitely AM radio towers, and in those days used to carry two stations, but I expect it will now be more. Most powerful was 1YA with 20kW carrier power, then 1YC and 1ZB (on a separate tower across the motorway) with 10kW each.

In the 70s, we used to climb onto the AM towers while they were live just by using a wooden ladder. The bottom of each tower is less than a metre off the ground because they sit on a large ceramic insulator.

I expect nowadays, this would not be allowed, and you would have to use a suit as Ray says, but in those days it was routine to just use a wooden ladder. I went up the 500 foot tower down in the Bay of Plenty once during the day and took a whole bunch of photos from the top. The views were spectacular, as you can imagine.

The entire tower IS the antenna, and the tallest one near Triangle Road is 500 feet high. It needs to be this long because of the wavelength of AM radio signals.

I remember this topic was on Closeup or Campbell Live last year some time. As I recall they mentioned a study that show childhood leukaemia rates are 4x as high for those living close to large power lines, but I can't find that study online (just an older one showing a doubling of the incidence rate).
I wouldn't mind living near them myself, but wouldn't take the slight risk with my young children.

mattwnz: Energy saver bulbs are also fluorescent, so should also glow under the same conditions.

Probably wouldn't work because the Field Strength which causes Fluoro bulbs to light, works on a Volts per Metre basis. With a standard Fluoro tube at close to a metre long, a decent voltage builds up to power the discharge. With a CFL, the distance from one end to the other is very short because it is in a coil, so there probably wouldn't be enough voltage unless you were in an immensely powerful electrical field. If that was the case, it would probably be most unwise to live there!

I do remember the fluoro tubes in the ACU huts beneath those masts at Henderson lighting up by themselves though. It gave a quick visual indication that the mast was live, so provided a useful warning.
