At High Technology Sources Ltd (HTSL), we are dedicated to providing solutions for radioactive isotopes, cutting-edge shielding, and sophisticated Non-Destructive Testing (NDT) equipment. Our commitment to precision and reliability is exemplified in our latest innovation: the GardU Gamma Automated Radiography Drive Unit. Designed to meet the evolving needs of industrial gamma radiography, the GardU System offers unparalleled safety and efficiency.
Why Automated Gamma Radiography?
In the field of industrial radiography, safety and compliance are paramount. Automated systems in interlocked exposure bays enhance safety and ensure adherence to radiation protection standards. According to the HSE IRR17 ACoP, “Where reasonably practicable, work involving exposure to external radiation should be carried out in a room, enclosure, cabinet or purpose-made structure which is provided with adequate shielding.”
While not legally required, many exposure bays are equipped with automated winding mechanisms linked to safety systems. These systems offer several benefits, including:
- Electronic Timing of Exposure: Precision in exposure duration.
- Safety Interlocks: Automatic retraction of the source if the safety circuit is broken, utilising magnetic door switches, grab wire safety ropes, or emergency stop buttons.
- Audio/Visual Indicators: Pre-warning and exposure notifications.
- Exposure Control: Ability to abort and resume exposure, ensuring fail-safe operations.
The GardU System: Advanced Automation for Enhanced Control
The GardU System is a game-changer in the world of gamma radiography. This fully automated exposure control system is designed to operate with all current isotope projectors, offering both stationary and portable options. Key features of the GardU System include:
- Fully Site Portable: Ideal for both on-site and in-bay applications.
- Advanced Control: Equipped with Siemens HMI and PLC for intuitive operation.
- Automated Exposure Control: Ensures precise and repeatable exposures.
- Visual Status Indicators: Provides real-time updates on source direction and position.
- Integrated UPS: Guarantees continuous operation even in the event of power interruptions.
- IRR17 Compliance: Meets stringent safety and regulatory standards.
HMI and Remote Control
The GardU System features a state-of-the-art Human-Machine Interface (HMI) with a TFT widescreen display, LED backlighting, and IP65 protection. The system is designed for ease of use with an uncluttered menu layout and intuitive controls. Additionally, the GardU Remote Control unit allows operators to manage the system from a safe distance, enhancing safety and compliance with ALARP (As Low As Reasonably Practicable) principles.
