Detailed introduction
ISO-CART-85 is a new mobile measurement system for radioactive waste analysis through high-resolution gamma spectroscopy. By using a single ultra-large area high-purity germanium (HPGe) detector and a modular collimation system, the ISO-CART-85 can achieve reasonable counting times at solution emission levels in many cases, making it suitable for field measurements.
The HPGe detector is available as the ORTEC IDM-200-V, a revolutionary all-in-one integrated gamma spectrometer that does not require liquid nitrogen to cool to operating temperature. A micro Stirling cooler is used here. The built-in battery powers the cooler and highly stable digital signal processing electronics for up to 3 hours, and an external battery option or hot-swappable battery capability allows for extended battery life.
The new system ISO-CART-II for mobile measurement is ORTEC's first generation of ISO-CART, which has been further enhanced based on operational experience and is also equipped with new options, such as a practical shield option for bottle containers, enabling the system to be used as a "field counting laboratory" for on-site measurement of large numbers of test samples. The ISOPLUS software has been tested in practice and its version is now compatible with 64-bit Windows operating systems.
The ISO-CART-85 system is available "out of the box" and is traceably calibrated at our factory. Standard configuration includes:
For those who wish to use their own laptop, a "User Installed and Calibrated" version is available. If calibration is required but a laptop is not required, calibration files are available for users to install on their own computers. ISOPLUS software allows systems to be calibrated or recalibrated at any time using traceable point sources. Therefore, there is no need to return to the factory for recalibration.

ISO-CART-85 Modular Collimator: The Lightest Weight Alignment Method
System weight is a major consideration for mobile metrology systems, which by definition must be able to move. The operation of the ISOPLUS software is based on the assumption that the detector "observes" representative material of the measured object through a defined "field of view" and then determines the total material on this basis. This requires the detector to be equipped with a collimator to limit and define a suitable field of view that is representative of the sample. Another consideration is that the detector itself may be exposed to external radiation from sources other than the object being measured (such as from other nearby waste samples). This may require the use of thicker collimators. For this reason and to ensure minimum weight, a modular collimator system was designed that improves upon a thinner, low-Z material-lined field collimator with additional detector shielding and thicker collimation required for background radiation.
The ISO-2-IDM-SHD kit includes three 15 mm thick, thin-walled steel, Sn/Cu-lined field of view collimators in 2", 4", and 6" lengths to provide different fields of view, and three 2" deep, 1" wall, lead cross-section shields for the FOV collimators (ISO-2-IDM-SHD-2). Selecting the appropriate field collimator and then adding additional shielding as appropriate ensures minimum weight.
ISO-CART-85 Bottle Sample Shield Extension Option: "On-Site Counting Lab" No Return to Base Required
In mobile analytical applications it may sometimes be necessary to collect a small sample of contaminated material (e.g. soil) and then analyze it in the "usual" measurement geometry (i.e. inside a lead shield), e.g. for screening purposes, to determine if the material is contaminated below the detection limit of collimated detection. The ISO-CART-85 shield extension can be mounted on an upward-facing 6-inch modular collimator and three 2-inch lead shields to form a small counting shield, allowing measurements of 1-liter bottle containers directly on the detector end cap, in an efficient measurement geometry.
ISO-2-IDM-SHD-EXT option includes shield extension for ISO-2-IDM-SHD, and six 1-liter bottles. Pre-calibrated ISO-CART-85 systems can be used directly with this option.
