1 Introduction
1.1 Product Description
RadTarge II | Personal Electronic Dosimeter is a series of all-digital electronic personal dosimeters
(EPD) covering a wide range of gamma and X-ray radiation that combines four functions in one:
Dose equivalent rate meter
Accumulated dose meter
Active self-reading dose meter
Active self-alarming dose meter
RadTarge II uses a high-performance YSO scintillation crystal combined with a state-of-the-art silicon
photomultiplier (SiPM) and multi-voltage threshold (MVT) algorithm to detect a wide range of
radiation doses.
RadTarge II protects users and notifies them of their environmental conditions instantly and
accurately. Proportional, real-time detection and measurement provide meaningful readouts that
focus on the awareness and safety of the user during critical times. The fast response and wide dose
rate range maximize the safety of your team. Audible, visual, and vibrating alarms alert the wearer of
alarm conditions. Intuitive navigation allows users to adjust settings in the field.
This pager-like, direct-reading EPD accurately detects and measures radiation exposure for workers
and responders in potentially hazardous environments. Its backlit LCD provides a clear indication of
the wearer’s equivalent dose rate and accumulated dose.
RadTarge II runs for 200 hours of continuous use on a full charge. Additional capabilities, including
data logging and personnel tracking, are available with the installation of RadSuite-Dose | Personal
Dose Management Software.
