Hello, thank you for your mail.
So I went immediately to the ministry of radiation protection in
Luxembourg and took the 7912 with me. We dismantled the power supply
there after ckecking the radiation outside the housing, and the
responsible person measured the beta and gamma radiation inside with
a geiger counter. Nothing could be detected except the normal natural
radiation. He took some probes of the dust and put them into a 'low
level counter' which measures the alpha and beta radiation (? the
measurement unit was bq, the instrument is normally used to measure
the 'natural' radiation from elements present in the earth in some
regions), and here too nothing could be detected apart from the normal
Are the symptoms I described typical for a contamination? Do you have
experienced simliar situations, or do you have other experience in this
field? Do you think the measurements I described are sufficient? The
responsible person proposed to make a measurement of the contamination
of the air in my room if I wanted to be really sure about it, but he did
Anyway, I'm afraid it seems that I still don't know what the source of
the problem is...

and post this later, if it doesn't show up on web:
WHERE is ".lu" ??
RUN, do not walk - to somewhere local where you can borrow a geiger
counter. If you can't find one, I can send you a Monitor4, about the
size of a calculator -- but that will take DAYS - depending upon where
.lu IS. If there is a Radiation exposure .org nearby or even many miles
away: CALL THEM NOW !!!
SWAB your entire body with damp paper towels and put these in Ziplock
bag. Have your family (?) do likewise - it may be a false alarm and
your symptoms (of flu, etc) merely coincidence.. but the salty taste is
hardly likely from 'flu'.
SAVE all dust in a Ziplock bag. *BAG that counter* and maybe tape the
door to that room SHUT, pending more INFORMATION. I spent one career in
physics research / accelerators: you are describing symptoms of a
possibly Bad emitter of betas and gammas - IF>> alphas also are present:
HOPE you did not touch your tongue, eyes with your dusty fingers..
Outside body, alphas are not much of a problem; typ. a piece of paper
will shield from their also massively *greater ionizing power*: they are
Helium nuclei, after all = Heavy.
This is an EMERGENCY SITUATION, IMO and from what you said. I will cc:
this to your e-mail as well as the forum. E-mail me for a phone
exchange, when you get this. Sounds as if you are unaware of some
radiation basics, which you next need to find out.
SAVE everything you had that equipment around since purchase - packing,
RECEIPTS etc - IF your instinct is right and the symptoms too - someone
has made an utterly UNACCEPTABLE ERROR, beginning with SANDIA LABS, who
may be paying your air fare for decontamination. They may be NEXT place
you call, after local help...
