Introduction
Excessive radiation exposure (misadministration) to the patient is always a matter of
concern in radiation therapy. The Dual-Diode Dosimeter eliminates this concern by
providing a dosimetry system specifically designed to verify the amount of radiation
received by the patient during treatment.
Applications
Measurements are presented on a large digital display with a range of 0 to 2000 Rad or
Rad/minute. The electrometer accepts either one or two diode detectors, which are
selected using a front-panel switch. Calibration and zero adjustments, as well as dose
or dose rate selection, are all readily accessible on the front panel.
While the Dual-Diode Dosimeter is not intended as a primary calibration device, it can
also be used to accurately determine therapy machine output.
