| RADTriageTM User’s Guide
RADTriageTM is part of the Self-Indicating Radiation Alert Dosimeter (SIRAD®) family of dosimeters. It is always active and ready to use, providing a quick and easy way to detect radiation exposure. RADTriageTM is a smart dosimeter, meaning it is capable of monitoring shelf life, false positives/negatives and tampering using a False-positive, Inactivation and Tamper indicator (FIT). It is considered a personal dosimeter because the credit card sized colorimeters are designed to be carried with you at all times - in a wallet, purse or with your employee identification badge.
RADTriageTM is a warning and casualty dosimeter. It supplements rather than replaces other dosimeters or detectors you may be required to use. It may be the only dosimeter worn by people who do not routinely work with radioactive materials and radiation sources.
Checking for Damage, Defect, and/or Expiration:
Ÿ The color of the sensor must closely match the zero bars of the color reference chart.
Ÿ The central dot of the FIT, located on the right hand side of the sensor, should be blue.
® A purple or red dot indicates that your RADTriageTM has been heated to at least 90oC which renders the sensor inaccurate.
® Do NOT use the dosimeter, if this is the case. Return it to the issuing organization with a description of the problem.
Ÿ The area surrounding the blue dot of the FIT indicator should be light blue.
® A color equal to or darker than the color reference bar on the right, indicates that your RADTriageTM has expired due to UV light, and/or high temperature exposure for a prolonged period. The sensitivity of the FIT indicator to X-ray is hundreds of times lower than that of the sensor. It will also develop a very faint blue color at 500 rads.
Ÿ The typical shelf life of RADTriageTM is one year after issue date.
® Keeping your RADTriageTM in the freezer extends the shelf life to five years.
Instructions for Care:
Ÿ Write your name and receipt date on the back of your card.
Ÿ Carry RADTriageTM in your wallet, purse, or pocket. It can also hang from your neck or belt like an ID badge.
Ÿ Keep the orange protective cover in place at all times. It can be lifted, when needed, for a more accurate reading.
® The cover protects the radiation sensor from ultraviolet (UV) light, near UV light, sunlight and fluorescent light.
® Colors referenced in this manual are without the orange filter, unless otherwise stated.
Ÿ Maximize usability and longevity of your RADTriageTM.
® Do not deliberately expose it to ionizing radiation.
® Protect it from high temperatures (above 140oF/60oC).
® Avoid prolonged exposure to UV light and sunlight.
® Keep your card in the freezer when you are not using it.
* This will extend the shelf life from one year to five years.
Ÿ A normal residential laundry cycle of washing and drying, below 175oF/80oC, has a negligible effect on RADTriageTM.
® Repeated laundry cycles or exposure to temperatures higher than 175oF/80oC will damage the sensors.
® Replace RADTriageTM if it is subjected to boiling water or more than one laundry cycle.
Instructions for Use:
Ÿ When exposed to radiation the SIRAD® sensing strip instantly turns blue.
Ÿ RADTriageTM can be viewed in any light.
® For higher accuracy, fluorescent lights are recommended.
Ÿ Estimate the exposure dose by matching the color of the sensing strip with the adjacent color reference bars.
® For higher accuracy, lift the orange filter.
® The dose is read in rads/mSv (1 rad = 1 rem = 10 mSv).
® If the color does not match exactly, but rather falls between two adjacent bars, the dose also falls between the two bars.
® The dose is estimated with approximately 80% certainty
NOTE: For 90% certainty, a spectrophotometer or optical densitometer can be used.
Reporting Exposure:
Ÿ If the sensing strip turns blue, report it to the department, agency, or organization who issued the dosimeter.
Ÿ If the dose reaches 25 rads or above, seek medical attention immediately.
Ÿ If the dose reaches higher than 100 rads, report to the nearest Emergency Room.
Detectable Radiation:
Ÿ RADTriageTM responds to the following:
® Gamma and X-ray with energy higher than 300 KeV
® Electrons and Beta Particles with energy higher than 1 MeV.
Ÿ RADTriageTM is not affected by normal exposure to diagnostic X-rays or security X-ray machines.
® More than five such exposures, however, will produce a detectable color change in the sensor.

Limited Liability
Reasonable efforts have been made to make this product free from defects. It is expected to perform as specified if used as recommended and instructions are followed. In the event that the product does not perform as specified, JP Labs will replace the product. JP Labs specifically disclaims all other warranties and liabilities expressed or implied. All warranties are null and void if any of the following occur: (1) the central dot of FIT indicator is red and/or area surrounding the dot is matching or darker than that of its color reference bar and (2) RADTriageTM is tampered with in any way.
