Gross alpha/beta measurement systems are specialized radiation counting solutions designed to measure total alpha and beta activity in environmental, industrial, and radiochemical samples. These systems are essential for applications where rapid screening or regulatory compliance is required, allowing users to quantify total radioactivity without performing full isotopic analysis. ORTEC provides a comprehensive portfolio of systems tailored to different operational needs: 1. Manual Counting Systems Designed for laboratories with low sample volumes and long counting times, these systems offer high sensitivity and simplicity. 2. Automatic Counting Systems Equipped with automated sample changers, these systems enable efficient processing of large sample batches, making them ideal for high-throughput laboratories. 3. Multi-Detector Systems (MDS) High-end solutions featuring multiple detectors (4–16 channels) for simultaneous measurements, delivering:

• High sensitivity

• Ultra-low background

• Maximum throughput

These systems utilize advanced detection technologies such as:

• Gas-flow proportional detectors → high sensitivity for alpha/beta particles

• Dual-phosphor scintillation detectors → efficient and flexible measurement

They are specifically engineered for low-background counting, ensuring accurate detection of very low radiation levels—critical in environmental and regulatory applications. With integrated software platforms, users can perform:

• Automated data acquisition

• Real-time counting control

• Compliance-ready reporting

System Types Manual single-sample systems (e.g., MPC-900 series) Automatic systems with sample changers (e.g., WPC-1050, WPC-1150) Multi-detector systems (MDS: 4, 8, 12, 16 detectors)
