RDS-SIM: Training Simulator for the RDS Detector and PDR 83

The RDS-SIM is a high-fidelity training simulator designed to replicate the full operational behaviour of the RDS detector, including configurations commonly referred to as PDR 83. It enables teams to train with the Ludlum Measurements Radiological Detection System without the need for ionising gamma or beta radiation sources.By accurately simulating detector response, alarms and probe behaviour, the RDS-SIM prepares operators to use RDS and PDR 83 systems confidently in real radiological and nuclear response environments.

Safe and Flexible Radiation Training

The RDS-SIM responds to safe electronic simulation sources that represent gamma and beta radiation signatures. This removes regulatory, environmental and health and safety constraints associated with live radiation training, while maintaining realistic detector behaviour.

Training can be conducted indoors, outdoors or in complex operational environments, including public spaces and live facilities.

Developing Critical Radiological Skills

Using the RDS-SIM, instructors can deliver high-quality training in:

  • Survey and localisation of radioactive sources
  • Isodose rate mapping
  • Shielding assessment
  • Safe demarcation of contaminated areas
  • Inverse square law response
  • Dose and dose rate management
  • Effects of shielding materials such as brick, wood and glass

These skills are essential for teams using RDS Ludlum Measurements systems during real incidents.

Advanced Simulation with Probes and Sources

The simulator supports encoded signals representing specific beta and gamma radionuclides. When the simulated beta window cover is opened, the RDS-SIM correctly responds to the beta component, reinforcing correct operational technique.

Additional simulation probes, including beta photon, sensitive gamma, neutron and FIDLER types, further extend training realism and scenario depth.

Multi-Detector and Scenario-Based Training

The RDS-SIM can be used with compatible dosimeter, survey meter and spectrometer simulators, enabling multi-detector and multi-isotope training within the same scenario. Chemical hazard releases can also be introduced to support combined CBRN exercises.

Wide area exercises with PlumeSIM

Integration with PlumeSIM allows teams to participate in real-time, instrumented wide area field exercises. This supports table-top and live training for radiological dispersal device scenarios and coordinated emergency response.

 

Cost-Effective Training for RDS and PDR 83 Users

The RDS-SIM operates on the same battery supply as the real instrument and requires no preventative maintenance or recalibration. This reduces cost of ownership and avoids accidental damage to operational RDS detectors and PDR 83 units, helping maintain readiness.

Who the RDS-SIM Is Designed For

The RDS-SIM is ideal for organisations that deploy RDS detectors or PDR 83 systems, including:

  • Emergency response and civil defence organisations
  • Nuclear and radiological incident teams
  • Military and defence units
  • Training centres and academies
  • Agencies using Ludlum Measurements RDS equipment

Understanding the RDS Detector and PDR 83

The RDS detector is a portable radiological detection system manufactured by Ludlum Measurements, widely used for radiation survey, reconnaissance and emergency response. In many operational contexts, the system is also known as PDR 83, particularly when configured for beta photon survey and dose measurement tasks.

The RDS-SIM ensures that training reflects the real-world use of RDS Ludlum Measurements instruments, preserving familiar workflows, controls and operational decision-making.
