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).
