7.7 Nal Scintillation Counter Probe LB 1234
The NaI Scintillation Counter Probe LB 1234 is offering a high
γ-sensitivity in the energy range between 25 keV and 2 MeV.
This makes it the ideal device to search for and rapidly detect
radioactive sources in radiation protection, in industry, in nucle-
ar medicine, in the laboratory and at authorities. Typical appli-
cations are in the transport control, waste monitoring, border
and baggage check, the control of scrap metal, the localization
of contamination or the activity measurement. The universal
battery-powered monitor LB 134 with data storage and adjusta-
ble alarm is used as measuring and display system.
