- Sensor Reference
The Sensor’s Colour Must be lighter than the Sensor Reference - Sensor
The Sensor instantly develops colour upon exposure to ionising radiation above 50 mSv and the colour intensifies with increased exposure to radiation. Colour development is permanent and cumulative. The exposed radiation dose can be easily estimated by matching the colour of the sensor with that of the adjacent colour reference bars. - False Reading and Shelf Life Indicator
The dosimeter expires when:
– the area surrounding the dark dots of the FIT indicator is noticeably darker than the colour reference bar to the right.
– FIT indicator is purple or red Reduced service life can come from overexposure to heat and UV/sunlight.



The RADTriage50™ dosimeter is always active and ready to use. The sensor instantly develops colour and the colour intensifies with an increase in radiation dose. The dosimeter monitors only medically significant doses (50-10,000 mSv). The colour development from exposure is cumulative and irreversible, this is especially important for individuals exposed to repeated diagnostic imaging, or long-term, lower-level radiation exposure.
