I used the badge during my work shift but I can’t measure the exposure until tomorrow. How should I store the badge in the meantime?

For maximum accuracy, badges are best read immediately after use. If you must store the badge, place it back in its original pouch, open-end first, fold the pouch end over a few times, tape the pouch closed, and store in the refrigerator. When ready to read the badge, let it equilibrate to ambient temperature before opening the pouch and inserting the sensor into the pocket viewer or digital reader.
