April 2004: It is clear that the mast has been decommissioned. There
are no antenna. It may have been sold as a job lot to NTL.

The only affect that I observed, entirely anecdotal, was when we transmitted 400 watts (PEP) on 10 metres (28.5Mhz). This may have disorientated local homing pigeons, to the annoyance of a local fancier. The pigeons sat on Douai Abbey roof for some hours after we stopped transmitting, and then they flew home. I have no research on that subject.
The devices on the Bovingdon tower look like directional microwave dishes. These are usually low power devices. If there is a risk from the mast, it must be so small that it should be ignored, when set against all the other risks we take on every day. The medical profession causes many times more radiation than all other nuclear fall out put together, and may account for up to 500 extra cancer deaths in the U.K. If logic drove all risk assessment the Parish Council would be questioning my requests for X-rays rather than directing its concerns about the radio mast.
Sources of known cancer causing Radiation. The Grey area is natural radiation. Note that vast bulk of the man-made radiation is medical. Radio waves are not known to cause cancer.
It is impossible to prove a negative, we can never say there is no risk given by radio transmissions. We have plenty of other known risk factors to work on, before considering that the risks of radio wave radiation to be a significant cause of cancer.
The following is from Hansard.
"Radio/Microwave Masts and Waves
Mr. Cousins: To ask the Secretary of State for Health what recent research he has commissioned into the health effects of radio masts and waves and microwave masts and waves. 
Yvette Cooper: A study on the incidence of leukaemia near all 20 high power TV/FM radio transmitters in Great Britain was published in 1996 by the Small Area Health Statistics Unit (SAHSU). This study found that there was no observed excess risk of leukaemia within 2 kilometres of all the transmitter sites looked at as a group. The Committee on Medical Aspects of Radiation in the Environment (COMARE) evaluated the results of the SAHSU study. In their statement COMARE reiterated their previous advice that there is no firm evidence of a carcinogenic hazard from exposure to electromagnetic fields (EMF) from TV and radio masts emissions.
Last year a report on mobile phones and health was published by the Independent Group on Mobile Phones, chaired by Sir William Stewart. The Stewart report provided a rigorous and comprehensive assessment of existing research considered the possible effects on health of mobile phones and base stations (masts). The report concluded that the balance of evidence indicates that there is no general risk to health of people living near base stations on the basis that exposures are expected to be small fractions of guidelines. Among its conclusions the Stewart group commented that the upsurge of mobile phone technology should be matched by good quality research. We have responded by setting up a new programme jointly funded by industry. The first call for proposals was issued on 9 February.
The Department is also continuing to provide financial support for the World Health Organisation International Electromagnetic Fields (EMF) Project which is comprehensively reviewing EMF effects, including those of radio waves. "
