Cancer by stations is problem
As SF Brown, of Oswestry, "spent 47 years of (his) working life in high powered wireless stations" (Letters August 19, 2006), he'll know that the three most powerful transmitters in the UK are at Crystal Palace, Sutton Coldfield and Wenvoe.
There have been several studios confirming elevated rates of cancers in these three locations. Just because Mr Brown has "not known of one complaint of ill-effects" does not mean that there haven't been any.
The London Borough of Bromley is very healthy in general, and yet Crystal Palace ward had the highest under-85 death rate in that borough during 1999-2003 according to the ONS data obtained by Philip Dunne MP. Many of those deaths will have been cancers.
If Mr Brown checks the 1999-2003 death rates of the 8,800 electoral wards in England & Wales, he'll find the majority of wards with high death rates are near sources of industrial PM2.5 pollution such as oil refineries, incinerators, cement works and power stations.
The UK government only acknowledges self-inflicted health damage.
