DoseGUARD™ Plus

 

Application

The new DoseGUARD Plus personal alarm dosimeter has been designed to meet the requirement in hospitals to measure the personal dose in Brachytherapy and radiopharmaceutical applications.
The DoseGUARD Plus covers a photon energy response range from 20 keV to 6 MeV, which includes low energy photon emitters like I-125 and Pd-103, and it is also sensitive for beta particles from 250 keV to 1.5 MeV.
The optional DCPS software gives access to the complete features of the instru-ment and allows the individual configuration of the instrument.

Features
• Multiple PIN diode detectors
• Sensitive to x-ray and gamma radiation, beta particle
• Photon energy response 20 keV to 6 MeV
• Beta energy response 250 keV to 1.5 MeV
• Variable alarms for dose and dose rate
• Suitable for all commonly used radionuclides (including I-125,Tc-99, I-131, Sr-90/Y90, …)
• Records whole-body (HP10) and surface dose (HP0.07)
• Dosimeter configuration software(DPCS) with infrared reader for customization of dosimeter settings
• Dose profile history with settable interval from 2 sec to 35 hours - stores up 579 records
• Lightweight and robust design
• Displays either Sv or rem (change via DPCS)

The instrument meets the requirements of relevant international standards(IEC1283, ANSI 13.11, 13.27and 42.20).
