How to Reset a Dosimeter

A dosimeter measures an individual's exposure to something within the environment. There are numerous varieties of dosimeters. The most familiar provides a measuring tool to detect radiation exposure for lab and x-ray technicians. Other possible models monitor sound, ultraviolet light and electromagnetic charges. Resetting the dosage scale back to zero between uses will give you an accurate reading every time you use a dosimeter. You should refer to the user's guide for your model for detailed instructions.
