>>"(Hint , why are high powered Airport Microwave Radar Transmitters are deliberately angled above the surrounding horizon on high towers with the absolute minimum power lobes sweeping ground level, and all terminal buildings and near by tall buildings where possible)."
Because, hopefully, the sky is where the planes are?
Because airport radar transmitters are seriously powerful, in the hundreds of kilowatts to megawatt range, rather than maybe tens of watts for a cell transmitter?
Because the less ground gets hit, the less reflected-back noise needs filtering out?
I wouldn't want to sit in front of a lighthouse beam, or dry my hair with a hot-air-gun, but that doesn't mean that light bulbs or hairdryers are necessarily going to kill me, just that I have a limited ability to cope with energy.
>>"We routinely use the word average , to hide all cluster spikes against the general population figures . where as a discerning mathematicians , actually uses bell curves by specific regions and towns to highlight trouble spots., because averages reveal very little information as to the true story of what is going on in any particular area!"
A discerning mathematician would understand that there will be some geographical clustering occurring even if some property is randomly spread.
A discerning epidemiologist would wonder what the cancer incidence was before a claimed cause actually existed, and what the expected figure might be from national averages - merely knowing what it is in some unspecified time after the claimed cause arrives doesn't actually provide useful information. Even then, a deviation from the average can easily be just the result of random chance.
A discerning medic might ask what the cancers were. If one was lung cancer in a lifelong smoker, and another was cancer in someone with a serious family history, that might be rather less concerning than 3 rare and less explicable cancers happening.
A discerning engineer might measure signal strengths in various places in the building, as well as in various places around the town, and make some conclusions from that. If a cancer had arisen in someone living low down in the building where any transmitter output would have been attenuated to below average city levels by passing through N floors, *that* couldn't easily be attributed to the rooftop transmitter.
A discerning neurotic would hear "3 cancers" and then demand the removal of the transmitter without bothering to look any further. They probably already 'just knew' they were dangerous even before they heard any anecdotal evidence.
