Product Description

RadWall S300 | Area Radiation Monitor is a next-generation all-digital area radiation monitor that combines three functions in one:

  • Alarm and display unit
  • Built-in scintillation detector
  • Self-healing and self-forming mesh network capable monitor

The RadWall-S Area Radiation Monitor uses a high-performance YSO scintillation crystal combined with a state-of-the-art SiPM (YSO+SiPM) and multi-voltage threshold (MVT) algorithm to detect a wide range of radiation doses. Armed with a high detection accuracy, high sensitivity, and fast response, as well as other significant advantages. The unit communicates with a wireless radiation monitoring network for data management. Proportional, real-time detection and measurement provide meaningful readouts that focus on real-world applications. The fast response and wide dose rate range maximize the safety of your team. The high-contrast OLED display provides a clear indication of dose rate. It can be used as a standalone Area Radiation Monitor, or multiple units can be combined to form a protected mesh network communicating via ZigBee IEEE standard. The RadWall-S has an alarm and display unit (ADU), providing detection and measurement with an internal scintillation detector. Forming the backbone of a scalable RadSafe Radiation Monitoring Solution, RadWall S300 | Area Radiation Monitor includes the RadSuite Monitoring Software to accommodate applications of any size or complexity.



  • "Indicator lights"
    • Green light indicates perfect working condition
    • Yellow light indicates problem
    • Red light indicates radiation intensity over the threshold
  • Display area of atmospheric absorption dose rate indicates the current Gamma air absorbed dose rate
  • Alert level of absorbed dose rate
  • User-set alarm threshold: 100 µrad/h–100 mrad/h (1 µGy/h–1 mGy/h) at 1 μGy/h (100 µrad/h) intervals




  • As an active self-reading device, dose rate is measured in real time, enabling user to always be aware of current exposure while simultaneously transmitting data to Radiation Monitoring System (RMS)
  • Two types of alarms alert users in multiple ways: audible and visual
  • Alarm is either preset or user programmable through entire measurement range
  • Proportional, real-time detection and measurement provide meaningful readouts which focus on the awareness and safety of the user during critical times
  • Built-in wireless communication for real-time, remote radiation monitoring, personnel tracking, and automatic reporting
  • Power redundancy with both electrical supply and UPS backup
  • Scalable platform achieves a variety of high and low intensity ranges with various types of Neutron and Gamma radiation probes

  • Airports, train stations, and subways
  • Major events security and crowded areas
  • Monitoring health physics, medicine, and other fields that use radioactive sources
  • Radiological diagnosis, treatment equipment, and shielded facilities
  • Dispensing and using of radiopharmaceuticals and disposal sites of radioactive waste
  • Online monitoring of radioactive sources and radiation devices
  • Metal recycling, building materials production, and other risks of radioactive pollution
  • Production, use, storage, and disposal of radioactive sources and radiation devices
  • Immigration office
