Heating and the safety of medical ultrasound, Magnetic Resonance Imaging and Mobile Phones
Francis Duck, professor at the University of Bath and Honorary Medical Physics professor at the Royal United Hospital, Bath.
BRLSI Wednesday 18th May 2011

Francis Duck graduated from Nottingham and obtained a PhD from London University.

Ultrasound 2 - 20MHz radio frequency.
MRI and Mobile Phones 50MHz – 2GHZ radio frequency.

·      This can cause tissue heating via the same mechanism as microwave heating in a microwave oven. (He did not state this himself)

·      Blood travels through the capillaries to carry away heat.

[On the speaker:
I find he has a very annoying manner. He speaks very badly dithering with “um” and “err” to waste time. He also has a poor rapport with the audience. His presentation is disorganised and the gaps in his delivery seem as though he is thought disordered.]

The human body rigorously regulated temperature to +0.1°C and -0.4°C over a 24 hour period.
·      Core temperature of 43°C would cause death.
·      Exercise could raise body temperature to over 40°C.

[On the speaker and the talk:
Strange facts and numbers don’t seem to really tie together very well.
What he said about how MRI works earlier in the talk means I don’t think he is reliable.
I think he might be depressed. His attitude is bad – I think he is trying to act like a “quack” a phoney doctor.]

·      Heat is not a carcinogen
·      Heat CAN DAMAGE PREGNANCIES!
-          Very scientifically rigorous data he assures us

[On the speaker and his talk:

One problem with his style is that it is very watery he isn’t really saying anything and also one does not feel comfortable sitting back and listening to what he says – one would have better things to say than him generally on physics. It is really a 1 slide talk. As I said I was thinking of the ducks going “quack” and how I chased a sitting duck off its perch on the embankment by the river into waking up and jumping into the river the other day.]

Criticism for the Tory Government in Britain

My criticism for Jacob Rees-Mogg and the Conservative Party would be from a financial perspective; the Tories have been poor on cost control and paying off stakeholders: extravagant wages and unpaid benefits bills. There have been no real compensation cases for human rights linked to the British education and qualifications system which is indicative of systemic failure at the grassroots. This means that there is a lack of opportunity for British people to do the work that they want to do; they are not being acknowledged. And a phoney social mobility scheme is propagating due to corporate culture being given precedence over British culture in public life.. I think the outlook could be negative for British finances with another credit rating downgrade for the UK, perhaps by two notches! My point is that it's the EU Pinkerton Agents getting the better of Tory government with Donald Tusk lording it over you from his office of power in the EU you won't get treated better in Europ…

Camden Crescent and Hedgemead Park

Here are my thoughts: Did you know that Camden Crescent, originally Camden Place and Upper Camden Place (which is now round the corner) was named after the Earl of Camden, Charles Pratt, who was Chancellor of the Exchequer so sponsored the scheme with his symbol on every door and crest of the exchequer on the decoration at the centre of the crescent? Charles Pratt was actually lord of Camden Place in Chislehurst in Kent. He was mates with William Pitt the Elder from Eton and Cambridge days. It was built 1788-1792 by John Eveleigh the architect.  One third of the 22 house crescent collapsed during a landslip which claimed 136 houses on the slopes of Lansdown Hill leading to the creation of Hedgemead Park below Camden Crescent. John Eveleigh was notoriously bankrupted in Bath, being called to the coffee shop in the Bath Chronicle by his creditors. Earl Camden was famous for supporting Fox’s Libel Act of 1792 which said that libel should be tried as murder with a jury regarding the poin…
