ISO-CART-85 is a complete mobile radioactive waste assay system designed for high-accuracy, in-situ gamma spectroscopy measurements in field environments. Built as a turnkey solution, the system integrates:

• A large-area HPGe detector (IDM-200-V)

• A mobile transport platform (ISO-CART-II)

• Advanced ISOTOPIC analysis software

• Modular collimation and shielding system

This combination allows users to perform non-destructive assay (NDA) of radioactive materials directly at the measurement site—eliminating the need to transport samples to a laboratory. A key advantage of ISO-CART-85 is its ability to achieve free-release detection levels within practical counting times, even in field conditions. The system is highly versatile and supports a wide range of real-world measurement scenarios, including:

• Waste drums and containers

• Pipes and industrial components

• Contaminated surfaces and structures

• Soil and environmental contamination

Unlike traditional HPGe systems, ISO-CART-85 uses a Stirling-cycle cryocooler, eliminating the need for liquid nitrogen. This enables:

• Fully portable operation

• Reduced maintenance

• Continuous field deployment with battery power

The modular collimator system allows users to define the detector’s field of view and optimize measurement accuracy depending on:

• Sample size

• Geometry

• Background radiation conditions

Additionally, the optional bottle counting shield transforms the system into a compact in-field laboratory, enabling high-efficiency measurement of small samples directly on-site. With its factory calibration, flexible configuration, and proven software, ISO-CART-85 is widely used in nuclear decommissioning, environmental monitoring, and waste management projects.
