Radiation Monitoring Watch (RMW) is a lightweight, compact, and low power gamma radiation monitoring gadget in the form factor of a wristwatch. It indicates prevailing dose rate, accumulated dose and current date & time. RMW also alerts the user with an audible alarm when the dose rate or accumulated dose exceeds the preset threshold.

Features
•    Continuous monitoring of the ambient gamma dose and dose rate.
•    Detects Gamma-Radiation through Geiger-Muller tube detector.
•    Audible alarm on preset accumulated dose and dose rate.
•    Water Resistant
•    Compact and light weight
•    Operates on a commercially available 3V coin cell.
•    Auto exit from “Set Mode” to normal operating mode after 30 sec of inactivity.

Specifications
•    Energy Range: 60 keV to 1.5 MeV.
•    Gamma dose rate measurement range:  0.04 µSv/h to 4mSv/h.
•    Sensitivity: 0.16CPS/µSv/h.
•    Alarm type: Audio.
•    Current consumption at background radiation level: 70 µA.
•    Battery life: more than 6 months (at background radiation level)
•    LCD refresh rate 10 seconds.
•    Auto adjustment of response time in the range of 10to 150 seconds.
•    Battery: Single CR 2450 Lithium battery (coin cell).
•    Dial Diameter: 52mm.
•    Weight: 65g (watch with battery).
•    Display Size: 1.28”.
•    Display Resolution: 128 pixels *128 pixels.

Applications
•    The Radiation Monitoring Watch is a compact hand wearable gadget. It can assist Emergency Response Personnel, Police &Security Staff, and First Responders while attending radiological emergency. It can also be used by the visitors to a Nuclear Facility.
