All in all probably right - ish.

But we don't intend to replicate that set up.

Can you tell a similar story about the largest Nuclear Site in Europe,
the French Commercial Reactors at Gravellines ?

Do you have the co-ords of the hotspots on the coast near Dounreay
I'd like to go and check them out.
you should see about 2-3 times background for that area.

Not at all easy to measure without an ultra low-background counter
and/or concentrating the sample then.


Not at all. If you get 5 clicks per minute on yer trusty geiger at home,
and 15 a minute there...


Depends on the accuracy you need. FWIR the standard deviation is equal
to the square root of the total counts. IE roughly speaking to get an
accuracy of 1.4% you need to aquire 10,000 counts. Might as well call
it 1-2 days and check into a hotel for a night or two. A problem with
counting as long as that is that the counting instrument can pick up a
burst of counts from EMI or detector malfunctions and you'd never
know, whats more the instrument has probably never been tested in such
a stringent application.

Thats how my friend did it back in the 70's. Hew was looking for
evidence of Nooclear CoverUps. Being a good leftie and all.

He found nothing at all except at sSellafiled, About 3x background. On
the beach


All the nuclear stations (except Trawsfynneth) sample fish in aquatic
environment, you can usually see a boathouse near the sea some
distance from the reactors with a nuclear counting lab and a small
boat in it. We equipped the Magnox stations with them.

The greens would have "Oi polloi" believe they have a monopoly on
environmental monitoring.

Dounreay was too far to travel too.


I've heard that there is a quarry somewhere near the Aberdeen ring rd.
(Anderson drive ?) that is reputed to be "red hot". I've not found it
yet, which is one reason I asked our learned friend where his supposed
"hotspots" near Dounreay are, but he appears to want to keep his
little twinkling light under a bushel.


Of course it all depends on precisely what you mean by "Hotspot".


Nice emotive term. A coal ash tip is hotter, and so is dartmoor.
