Product Description

Safety Cards

With Two Sensors -  One for triaging radiation exposure and another for monitoring tampering

  1. Radiation Safety Sensor: Develops a green/gray color, monitors 20-10,000 mSv (2-10,000 rad) and provides early warning
  2. FIT™ (False positive/negative, Inactivation and Tamper) Indicator: Multi-indicator (1) central dot changes from dark blue-to-red if heated maximum operating temperature, 90°C (2) area surrounding central dot turns blue simultaneously monitors shelf-life expiration and/or if a false positive has occurred due to prolonged exposure to high temperatures and UV/sunlight
  • Dose Integration: Cumulative, Response time: Instant
  • Response retention: Full, Effect of Dose rate: Negligible
  • Uncertainty: Visually: Dimensions: Size of credit card (Length: 8.5 cm, Width 5.5 cm, Thickness 0.5 mm, Weight: 2 g)
  • Energy dependency: Independent of energy (Over 30 KeV X-ray)
  • Post radiation effect: 90-95% color development within minutes, the rest within hours
  • Effect of temperature of radiation: Negligible (less than 0.1%/°C over minus 20°C to plus 60°C)
  • Maximum operating temperature: ~90°C (Temperature on a car's dashboard under direct sunlight can reach as high as 80°C). FIT™ Indicator will monitor such exposure
  • Laundry resistance: Passes a few residential laundry cycles
  • Effect of average humidity: None
  • Effect of sunlight: Negligible for a week of average direct sunlight (two weeks of winter and a few days of summer sunlight). Dosimeters can be read a thousand times under sunlight. FIT™ Indicator will monitor overexposure to UV/sunlight
  • Effect of ambient light: negligible for a month
  • Support equipment: None needed to estimate dose
  • Service life: One years at 22°C or when color of FIT™ Indicator matches its color reference bars

Other unique features:

  • Tamper resistant and tamper evident. Other internal indicators for monitoring false positives, false negatives, and tampering
  • No electronics or moving parts, reliable, rugged and useful for radiation protection and triaging radiation exposure information and medical treatment
