AW: [ RadSafe ] Subsea detector required

[Franz Schönhofer]

Joe,

I cannot tell you a supplier, but I would recommend to contact the Marine
Environmental Laboratory (MEL) of the IAEA in Monaco, preferably Joan-Albert
Sanchez-Cabeza (please give him my regards). I know for sure, that the
laboratory was working with a submersible Ge(?)-detector and wanted to use
it also during the International Mururoa Project of the IAEA in 1996. I do
not know for sure, whether they actually were successful on Mururoa,
throughout the three weeks I was on Mururoa and Fangataufa with my
terrestrial working group, partially overlapping with the aquating working
group, I have not heard of it. What I have heard, was that there were
problems, because the sea floor within the atoll was of course not flat, but
full with small and big coral "towers" and other obstacles.

Joan Albert was then not yet working at MEL, but he sure knows who was and
probably is still involved in the project on ocean floor measurements.

Good luck!

Franz

Dear members

UKAEA are planning to undertake some investigative work offshore of
Dounreay in Oct/Nov 2007. Part of this work would need a radiation
detector with spectral capability (NaI, CdZn, BGO..) which is protected
for
work in seawater up to 60 metres depth. It would also need to fit down
an
unlined borehole about 75mm wide, and preferably attached to a 1-inch
wide
camera, so the narrower the detector the better.
Our regular suppliers have been unable to provide the kit, either
because
their detector/housing is too large, or they cannot provide long enough
signal cable (we need approx 100 metre cable to ship).
Can anyone recommend a supplier of detector and associated MCA, either
to
purchase or to borrow for a couple of months?

kind regards

Joe Toole
