Cell Towers are the base stations which control cell phone communication. The generic term “cell site” can also be used – to include all cell phone towers, antenna masts and other base station forms. Each cell site services one or more “cells”.
Cell tower numbers have grown exponentially in recent years, as service providers raced to improve their coverage.
Increased cell phone traffic also contributes to cell tower density. When a cell becomes too busy, a frequent solution is to divide it into smaller cells, which then require more cell sites.
In 2009 there were over 200,000 cell sites in the USA alone, and 50,000 in U.K.
Cell tower radiation from chimneys?
Cell sites may take the form of a mast or tower, but may also be disguised, in some cases so they cannot be visually discerned at all.
You might notice the camouflaged “trees”, but perhaps not the cell sites on top of buildings, looking like elongated loudspeaker boxes.
You’d almost certainly miss the cell sites installed inside chimneys and church steeples, even flagpoles.
Where a base station is installed on top of a building where people live or work, those occupants may be quite unaware that they are in very close proximity to equipment which produces substantial electromagnetic radiation.
Cell tower health dangers
Cellular phone industry spokespersons continue to assert that cell phone towers pose no health risk. Almost all scientists in this field would disagree, at the very least claiming that no such assurance can be given.
There is strong evidence that electromagnetic radiation from cell phone towers is damaging to human (and animal) health.
A study into the effects of a cell tower on a herd of dairy cattle was conducted by the Bavarian state government in Germany and published in 1998. The erection of the tower caused adverse health effects resulting in a measurable drop in milk yield. Relocating the cattle restored the milk yield. Moving them back to the original pasture recreated the problem.
A human study (Kempten West) in 2007 measured blood levels of seratonin and melatonin (important hormones involved in brain messaging, mood, sleep regulation and immune system function) both before, and five months after, the activation of a new cell site.
Twenty-five participants lived within 300 metres of the site. Substantial unfavourable changes occurred with respect to both hormones, in almost all participants.
Over 100 scientists and physicians at Boston and Harvard Universities Schools of Public Health have called cell phone towers a radiation hazard.
Cell phone towers cancer risk
A study performed by doctors from the German city of Naila monitored 1000 residents who had lived in an area around two cell phone towers for 10 years. During the last 5 years of the study they found that those living within 400 meters of either tower had a newly-diagnosed cancer rate three times higher than those who lived further away. Breast cancer topped the list, but cancers of the prostate, pancreas, bowel, skin melanoma, lung and blood cancer were all increased.
Another study by researchers at Tel Aviv university compared 622 residents who lived within 350 meters of a cell phone tower with 1222 control patients who lived further away. They found 8 cancer cases in the group affected by the cell tower, compared with only 2 cases amongst the controls.
Very few studies have specifically concentrated on cancer risk from cell phone towers. This lack of studies is in itself a cause for concern, especially since anecdotal evidence is plentiful.
For example, in a case known as “Towers of Doom”, two cell masts were installed (in 1994) on a five story apartment building in London. Residents complained of many health problems in the following years. Seven of them were diagnosed with cancer. The cancer rate of the top floor residents (closest to the tower) was 10 times the national average.
We agree that more research is needed, but it may be slow in coming. Those who might fund major studies are the very same organisations who would be disadvantaged if a definite link between cell towers and cancer were established.
In the meantime, it is reasonable to apply the precautionary principle.
If cell towers are causing cancer, we would expect that several years of exposure (with only minor effects on people’s health) might be required, followed by an unexpectedly high occurrence of the disease amongst the exposed population.
The damage from radiation exposure accumulates over many years, but the breakdown in health happens only after all body defences and repair mechanisms have been exhausted.
At an international health conference, 33 delegates from seven countries declared cell phone towers a public health emergency.
