DoseAlert™ RX-80 Personal Radiation DosimeterGeiger-Mueller real-time dosimeter — light / audible / vibration alarms
DoseAlert RX-80 portable electronic personal radiation dosimeter. Geiger-Mueller tube spans 0.05 to 6 MeV gamma and X-ray; real-time LCD readout shows instantaneous dose rate (0.1 µSv/h to 36 mSv/h) and integrated dose (up to 100 Sv). Three independently configurable alarm modes — light (high-visibility LED on the upper corner, visible to surrounding people too), audible buzzer, vibration — trigger on programmable DER and DE thresholds. Rechargeable 2 × AAA NiMH battery delivers 800-hour typical life, 4-hour dock-station charge; USB-connected DoseAlert software archives the dose history and generates per-operator reports. The active companion to the passive TLD / OSL badge — immediate feedback during the working day.
Key Features
- Geiger-Mueller tube detector — proven, robust detection across the radiation-safety energy band (0.05 to 6 MeV gamma and X-ray)
- Real-time LCD shows BOTH instantaneous dose rate and integrated dose — operator sees the field as it is, not just the cumulative readout at month-end
- Three independently configurable alarm modes — light (high-visibility LED on the upper corner), audible buzzer, vibration — pick the right combination per environment
- Programmable threshold alarms on dose-rate (DER) AND integrated dose (DE) — operator gets warned both BEFORE the environment escalates and AFTER an accumulated-dose budget is consumed
- Dose-rate range 0.1 µSv/h to 36 mSv/h — covers diagnostic NM background through high-activity PRRT dispensing without changing instruments

- Integrated dose accumulation up to 100 Sv — well beyond a working lifetime
- Dose measurement accuracy ± 15–20 % of reading
- Rechargeable 2 × AAA NiMH 1000 mAh — 800 hours typical battery life at ≤ 0.3 µSv/h average; 4-hour full charge in the DoseAlert Dock Station
- Compact 95 × 55 × 16 mm, 150 g — clip-on form factor for chest-height wear over lab coat or apron
- IP31 ingress-protection rating — tolerates spills, humidity and the hot-lab fume-hood environment
- Operating temperature -20 °C to +60 °C — robust against cold-chain corridors and warm hot-lab cabinets
- 10-year mean service life — long capex amortisation horizon for the radiation-safety budget
- Periodic automatic self-test of detector and batteries — failure mode surfaces at power-on, not at the quarterly badge read
- On-board real-time clock — every dose record in non-volatile memory carries a timestamp the AERB inspector can audit
- USB connectivity via the DoseAlert Dock Station; DoseAlert PC software archives dose history, generates per-operator reports for the occupational-dose file
- High-visibility LED on the upper corner — alarm indication is visible to both the wearer AND surrounding personnel, which matters in shared dispensary spaces
- Suitable for nuclear-medicine hot-lab staff, theranostic ward nurses, cyclotron operators, radiopharmacy technicians and RSO field work
- Calibration certificate supplied; in-country annual calibration support available through Saxsons

Applications
The active companion to the passive badge — real-time feedback during the working day
Nuclear-medicine hot-lab staff
Real-time dose-rate readout during high-activity dispensing days (theranostic prep, Lu-177 / I-131 patient dosing). The operator sees the current radiation environment and adjusts behaviour mid-shift, rather than learning the cumulative exposure at the next badge read.
Theranostic ward — Lu-177 / I-131 nursing staff
Continuous dose-rate monitoring during patient bedside care. The vibration-only alarm at a configurable rate threshold gives a non-audible cue to step back — useful in patient-care environments where audible alarms would be disruptive.
Cyclotron operator
Beam-on / beam-off interlock work, target service, hot-cell access — the RX-80 records actual occupational dose during high-rate events and timestamps every record, complementing the passive badge.
Radiopharmacy clean-room
F-18 / Ga-68 / Lu-177 dispensing and QC work. The real-time readout flags an unusual dose-rate spike — useful for detecting an unshielded vial or a damaged shielding cap before the cumulative dose accumulates.
RSO field work
Inspection visits to wards, source-storage areas, waste rooms. The dock-station-archived history records dose vs. timestamp across the whole inspection day rather than relying on the inspector's recollection of where they walked.
Trainee dose-awareness
New radiopharmacy / NM-technologist trainees benefit from real-time dose feedback — the RX-80 makes the otherwise-invisible field visible during the first months of clinical work.
Why DoseAlert™ RX-80 Personal Radiation Dosimeter?
A Geiger-Mueller tube is the proven, robust detector for the radiation-safety energy band. Spans 0.05 to 6 MeV — covers everything from diagnostic-NM gamma to PET annihilation lines and high-energy bremsstrahlung. Energy compensation keeps response flat across the band; what the LCD shows tracks the dose-equivalent quantity the AERB inspection cares about.
Three alarm channels — independently configurable — let the operator pick the cue that fits the environment. Vibration-only at the theranostic patient bedside; audible + light in the hot lab; high-visibility LED in shared dispensaries so colleagues see the alarm too, not just the wearer. The LED sits on the upper corner of the device, deliberately visible to surrounding people.
Rechargeable 2 × AAA NiMH delivers 800 hours of typical use at routine dose-rate levels. A full hot-lab shift (8 h/day, 5 days/week) runs ~10 weeks per charge. The DoseAlert Dock Station does a full top-up in 4 hours — drop it in overnight, pick it up in the morning, ten more weeks of work.
