Active Monitoring with Electronic Dosimeters

An Electronic Personal Dosimeter (EPD) may be a useful tool if you work with significant quantities of radioactive material, receive notifications about high dose on your dosimeter, or wish to better understand the source of the dose you receive.  Contact your primary Health Physicist, or email, to discuss the EPD loaner program.  For information on an existing EPD on loan from the ORS, see the help sheet linked here.
