RadWall S300 – Area Radiation Monitor


RadWall-S | Area Radiation Monitor is an all-digital area radiation monitor covering a wide range of gamma and X-ray radiation.

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

RadWall S300 | 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.

RadWall S300 | Area Radiation Monitor has high detection accuracy, high sensitivity, and fast response, as well as other significant advantages.

RadWall S300 | Area Radiation Monitor 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.

RadWall S300 | Area Radiation Monitor 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.

RadWall S300 | Area Radiation Monitor is 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-Monitor 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
