Fritz,

You did not specify, what kind of measurements you need the survey
instrument for. Is it in the field, in decommissioning work....? What kind
of material do you want to check? Water, concrete, tritium in air, surface
contamination? What is the range of radionuclide activity concentration you
expect?

Without this information it will be hardly possible to give you a good
advice. As far as I remember there exist measurement devices for tritium in
air, but they work only with very high concentrations - which is not
surprising. If it is in water you will hardly be able to avoid LSC!

Best regards,

Franz
