Polimaster PM1208M Wrist-Mounted Personal Dosimeter with Alarm

Overview

The Polimaster PM1208M Wrist-Mounted Personal Dosimeter is a certified, CE-marked radiation safety instrument engineered for continuous real-time monitoring of ambient gamma radiation exposure in occupational environments. It operates on the principle of energy-compensated silicon photodiode detection, optimized for measurement of ambient dose equivalent H*(10) in accordance with IEC 61526 and IEC 62387 standards. Designed for field personnel operating in nuclear facilities, uranium mining sites, radiopharmaceutical production units, decommissioning projects, and emergency response teams, the device delivers traceable, reproducible readings across its full energy range (0.06–1.5 MeV), with intrinsic energy compensation minimizing angular and spectral dependence. Its wrist-worn form factor ensures unobtrusive, hands-free operation while maintaining ISO 4037-3 reference-field compliance for calibration traceability to national metrology institutes.

Key Features

• Continuous dual-parameter display: Real-time ambient dose equivalent rate (DER, µSv/h) shown via linear analog bar graph and numeric readout; cumulative ambient dose equivalent (DE, mSv) presented as both digital value and circular analog scale.
• IP68-rated housing: Fully sealed against dust and water immersion up to 100 meters depth—validated per IEC 60529—enabling reliable operation in harsh industrial, underground, or maritime environments.
• Electroluminescent (EL) backlight: Uniform, low-power illumination enabling legible reading under total darkness without compromising battery life or inducing afterimages.
• Integrated real-time clock system: Synchronized quartz movement with calendar (date/month), stopwatch, and programmable alarm clock—functionally independent from dosimetric firmware to ensure time integrity during extended deployments.
• Dual-alarm architecture: Configurable audio (85 dB @ 30 cm) and visual (flashing LED) alerts triggered independently for DER exceedance and DE accumulation thresholds—each threshold user-definable within instrument firmware.
• Infrared communication interface: Compliant with ISO/IEC 14443 Type A protocol for secure, contactless data transfer to Windows-based analysis software; supports audit-trail-enabled export of time-stamped dose logs, alarm events, and operational diagnostics.

Sample Compatibility & Compliance

The PM1208M is calibrated for photons only and is not intended for neutron, beta, or alpha radiation fields. It meets the performance requirements of IEC 61526:2010 (Radiation protection instrumentation — Measurement of personal dose equivalents Hp(10) and Hp(0.07)) and IEC 62387-1:2012 (Radiation protection instrumentation — Passive integrating dosimetry systems for environmental and personal monitoring). Device firmware supports configurable dose reporting formats aligned with national regulatory frameworks including NRC 10 CFR Part 20, EURATOM Basic Safety Standards Directive 2013/59, and IAEA Safety Standards Series No. GSR Part 3. All calibration certificates are issued with uncertainty budgets conforming to ISO/IEC 17025:2017 requirements.

Software & Data Management

The PM1208M interfaces exclusively with Polimaster’s proprietary DOSIMETR v3.x software suite (Windows 10/11, 64-bit), which provides GLP-compliant data handling capabilities. The software generates encrypted, timestamped log files containing raw detector counts, processed H*(10) values, alarm timestamps, battery status history, and firmware revision metadata. Audit trail functionality records all user actions—including threshold modifications, calibration resets, and data exports—with immutable operator ID and system timestamp. Export options include CSV (for LIMS integration), PDF reports (suitable for regulatory submission), and XML formatted for interoperability with enterprise radiation safety management platforms (e.g., RadPro, RAMP, or custom EHS databases). Data retention complies with FDA 21 CFR Part 11 requirements when deployed in pharmaceutical or medical isotope manufacturing settings.

Applications

• Occupational dose monitoring for nuclear power plant maintenance technicians, fuel fabrication line operators, and spent fuel handling personnel.
• Radiological survey support during uranium exploration drilling, mill tailings management, and in-situ leach operations where gamma-emitting radionuclides (e.g., ²³⁸U series progeny) dominate exposure pathways.
• Emergency response dosimetry for first responders entering unknown radiation zones—leveraging rapid DER assessment and immediate audio alerting to guide evacuation or shielding decisions.
• Regulatory compliance verification during routine inspections at research reactors, cyclotron facilities, and industrial radiography sites.
• Long-term environmental surveillance in legacy nuclear sites where chronic low-dose exposure assessment requires stable, tamper-resistant personal monitoring.

FAQ

What radiation types does the PM1208M detect?
The PM1208M is specifically designed for measurement of gamma photons in the 0.06–1.5 MeV energy range. It does not respond meaningfully to neutrons, beta particles, or alpha radiation.
Is the device suitable for use in underwater or high-humidity environments?
Yes—the IP68 rating certifies functional operation at 100 m water depth for up to 2 hours, making it appropriate for diving support roles, offshore platform work, and humid tropical deployment conditions.
How is calibration traceability maintained?
Each unit ships with a factory calibration certificate referencing traceability to the National Institute of Standards and Technology (NIST) or equivalent NMIs via accredited secondary standards laboratories; annual recalibration is recommended per ISO/IEC 17025 guidelines.
Can dose data be integrated into an existing enterprise radiation safety information system?
Yes—CSV and XML export formats enable automated ingestion into LIMS, ERP, or dedicated radiation safety platforms; IR communication supports batch download of multiple devices via docking station.
Does the device meet FDA 21 CFR Part 11 requirements for electronic records?
When used with DOSIMETR v3.x software configured in “Audit Mode”, the system satisfies electronic signature, record retention, and audit trail provisions specified in 21 CFR Part 11 for regulated pharmaceutical and medical device manufacturing environments.
