Portable Radiation Detector
Survey Meter MSV-100G
MSV-100 is a portable wide-range radiation survey meter designed to detect radioactive materials and contamination caused by radiation. As the world’s first hybrid radiation monitor applying both a semiconductor sensor and a Geiger-Müller counter tube (GM-Tube) simultaneously (Dual Sensor), it provides fast response and high precision across both low and high dose ranges for alpha, beta, gamma, and X-ray radiation. It is also an ICT-based hybrid radiation monitor designed to enhance user safety.
Applications
Suitable for radioactive material transportation, nuclear industry workers, nuclear power plants, nuclear research institutes, non-destructive testing (NDT), emergency rescue teams, civil defense organizations, fire departments, hospitals, defense sectors, anti-terror organizations, and police agencies.
Developed using SFT Technology’s patented technologies, including “1:N Sharing of Radiation Detection Data, Realistic Recognition Device and Method” and “Portable Radiation Measurement Device Using GM-Tube and PIN Diode with Remote Radiation Transmission/Reception System and Method (Survey Meter with GPS and CDM).”
Main Functions
- High-precision measurement with fast response characteristics
- First in Korea to apply dual sensors combining semiconductor and GM-Tube technology
- Excellent sensitivity for alpha, beta, gamma, and X-ray detection
- Alarm function for dose limit exceedance and cumulative dose measurement
- Wireless communication function for transmitting location and radiation measurement data to the radiation monitoring server
- Remote monitoring through smartphone app connectivity via Bluetooth and remote PC monitoring system (hybrid radiation exposure monitoring device)
- Backlight and vibration functions
- Intuitive information display for enhanced user convenience (PUI)
- The upper part of the device is mainly designed for display, calculation, and operation functions, with rubber sealing applied for dustproof and waterproof protection during outdoor activities
- The lower part of the device is designed to be combined with different module types according to user requirements for each model
