PROPERTIES OF RADTriage^TM, A SMART RADIATION DOSIMETER

• 
• Sensors: Three (two for monitoring radiation and one for treatment conditions)
• Warning Sensor: Develops blue color to monitor 2-50 rads. Provides early warning to users.
• Casualty Sensor: Develops purple color to monitor 50-1,000 rads. Helps first responders to guide medical treatment.
• FIT Indicator: Multipurpose indicator (1) develops blue color to monitor shelf life and false positives
   from overexposure to high temperatures and UV light and (2) central dot changing from blue-to-red
   monitor false negatives and inactivation of blue sensor.
   
• Lowest limit of detection:
• Visual:
• Warning Sensor: 2 rads first bar (1 rad can be noticed)
• Casualty Sensor: 50 rads first bar (25 rads can be noticed)
• Spectroscopy or optical densitometry: Warning Sensor: ~ 0.5 rad
• Dose Integration: Integrating/cumulative
• Response time: Instant
• Response retention: Full
• Dimensions: Length 8.5 cm, Width 5.5 cm, Thickness 0.1 cm, Weight: 5 grams 
• Energy dependency: Independent of energy (Over ~30 KeV X-ray)
• Post radiation effect: 90-95% color development within minutes, the rest within a hours
• Effect of Dose rate: Negligible, if any
• Effect of temperature of radiation: Negligible (less than 0.1%/^oC over -20^oC to +60^oC)
• Laundry resistance: Passes a few residential laundry cycles
• Maximum storage temperature: ~90^oC for ~six hours
• Effect of average humidity: Negligible, if any
• Support equipment: None needed for estimation of the dose
• Archiving: By heating at 120^oC followed by a rapid cooling to room temperature

Other unique features

• Tamper resistant
• Tamper evident
• Scratch-off bars on both the sensors to monitor/detect UV exposure/false positives
• Inaccessible bars under both the sensors to monitor/detect UV exposure/false positives in case of disputes
• A few other internal indicators to monitor false positives, false negatives and tampering
