DoseRAE is a lightweight, direct-reading electronic personal dosimeter that provides superior dose monitoring accuracy. The sensitive and sturdy Geiger-Mueller tube of the DoseRAE provides accurate dose readings with a resolution of less than 0.02 µSv (2 µR).

DoseRAE alerts the wearer with a loud 75+dB alarm and big, bright flashing LEDs. DoseRAE tracks stay-time, the amount of time left until the dose alarm level is reached if the wearer stays in the current radiation field.
