May I remind you, that you yourself have in the course of your work for the
infamous "Gammameßstelle" in Vienna recorded quite a few spectra - didn't
you save them..... (No pun intended, I am just teasing you...) You should
know that my laboratory has collected hundreds if not thousands of spectra
during the "critical time". I only remember that E Henrich has changed all
the time the storing routines, going from PDP 11 RL01 to RL02 etc. I do not
know what happened with all those backup media, but I am rather sure that
they cannot be read anymore. I have not bothered to follow the tracks, but
if anybody might give you an answer when it comes to Austria it might be Mr.
Katzelberger at AGES. Otherwise I would recommend to contact for instance
the Swedish Radiation Protection Institute (SSI) or the Finnish one
(Säteiliturvallisuskeskus), where high concentrations were recorded. The
same is true for Munich-Neuherberg and many others also in some Eastern
parts of Europe.
For me it is a confirmation of my scepticism toward the more than rapid
development of digital storage techniques because at every change
information gets lost.
I heard that you have a new job? Gratulations!

Betreff: [ RadSafe ] Airfilter gamma spectrum 1986
I am in search for a high resolution gamma spectrum of an airfilter of
around 1 May 1986, in digital format. Activity load, air volume or
sampling time should be rather high, so that as many "exotic" lines of the
Chernobyl cloud as possible are visible. (Thus this request is probably
mainly directed to colleagues in Central and Eastern Europe.)
I would need it in txt format: (channel #, counts). Energy cal. would be
a nice addition, but if unavailable I can find it out myself from the
spectrum. I am not interested in quantitative results (Bq/m^3), so
sampling time, air flow and eff. cal. are not of interest.
I need it for a report for demonstration of what a gamma spectrum in such
a situation may look like. Unbelievably, although so many measurements of
that kind were made, it is difficult to find any in *still readable*
digital format. (A case for archeology of science.)
Thanks for any hint.
