The Integrated Sample Counter is a field-deployable alpha/beta sample counter that provides high-sensitivity alpha and beta activity determinations on filters and swipes. It can determine radon working levels or it can perform real-time compensation for radon-decay products when trying to detect other alpha-emitting isotopes-of-interest. SabreISC can be configured with up to two alpha-emitting isotopes-of-interest and has the unique ability to match an unknown peak to the nearest radionuclide in the user-editable isotope table. It simultaneously measures beta and is a fully integrated instrument with a high-resolution color LCD/touchscreen and electronically-controlled sample drawer.

Benefits

Available in alpha/beta and alpha-only configurations. Activity determinations for up to two different alpha-emitting isotopes with simultaneous beta reporting. Uses an alpha peak-shape fitting algorithm that is more accurate than region-of-interest or tail-fitting methods of radon background subtraction. Can perform Radon Working Level Measurements on filters of known sample volume and age. Automatic minimum-count time mode with complete data logging (including spectral data). Live “strip chart” display of activity, detection limit, action level, and elapsed time. American or SI units. Built-in battery backup.
