1.  RADTriage  is  the  only  credit  card  sized,  instantly  color  developing,  emergency  dosimeter  for monitoring  medically  significant  dose  of  ~20  mSv  (diagnostic/tolerable  dose such  as  a CT  scan) through ~10,000 mSv (fatal dose) to minimize panic and worry, and to triage radiation exposure for medical treatment during a radiological incident.

2.  RADTriage is a user friendly, light weight (3 grams), failproof (no moving or electronic parts), wearable 24/7,  always ready without  a power source, stockpileable  for  ten  years, practically  non-destructible  and  readily  deployable  dosimeter for  a radiological  emergency.  

3.  It  is  tamper-resistant  and  tamper-evident.  It  does  not  need  a  reader, batteries,  calibration  or maintenance.
