Overview
The Beigu BS2010 Personal Dosimeter and Dose Rate Meter is a compact, CE-compliant radiation monitoring instrument engineered for real-time measurement of both ambient dose equivalent rate (Ḣ*(10)) and accumulated personal dose equivalent (Hp(10)). Designed in accordance with IEC 61526:2010 and aligned with ISO 4037-3 reference radiation fields, the BS2010 employs a compensated Geiger-Müller (GM) tube detector to deliver reliable performance across a broad photon energy spectrum—from 48 keV to 1.5 MeV—while maintaining ≤ ±25% energy response deviation. Its dual-mode operation supports occupational health surveillance in environments where personnel are routinely exposed to ionizing radiation, including nuclear medicine departments, industrial radiography facilities, non-destructive testing (NDT) sites, and environmental remediation zones. The device operates autonomously without external calibration sources and integrates hardware-level energy compensation to minimize spectral dependence, ensuring metrological traceability under variable field conditions.
Key Features
- Simultaneous real-time display of dose rate (0.01 µSv/h – 30 mSv/h) and cumulative dose (0 – 9999.99 mSv), updated every second
- User-configurable alarm thresholds for dose rate, accumulated dose, battery low, sensor fault, and over-range conditions
- Triple-mode alert system: audible tone (≥ 85 dB at 30 cm), red LED flash, and tactile vibration—optimized for high-noise or glove-operated scenarios
- Robust angular response compliance: ≤ ±15% deviation up to 45° incidence; ≤ ±30% up to 90°, meeting IEC 61526 angular dependency requirements
- Low-power architecture (200 hours of continuous operation on a single full charge
- IP54-rated housing constructed from impact-resistant engineering thermoplastic, certified for use in humid (≤90% RH at 40°C) and sub-zero (−20°C) operational environments
Sample Compatibility & Compliance
The BS2010 is validated for use with X-ray, gamma, and high-energy beta radiation fields encountered in diagnostic radiology, radiotherapy support, industrial radiography (e.g., Ir-192, Co-60), and sealed-source applications. It conforms to national metrological verification regulation JJG 393-2021 (China) and satisfies essential requirements of the EU Radiation Protection Directive 2013/59/Euratom for personal dosimetry instrumentation. While not a TLD or OSL-based passive dosimeter, the BS2010 serves as a primary active monitoring tool for immediate dose assessment and ALARA (As Low As Reasonably Achievable) enforcement. Its firmware implements audit-ready logging (timestamped dose events, alarm triggers, and battery status), supporting GLP-aligned record retention protocols.
Software & Data Management
Data export is supported via USB-C interface using Beigu’s proprietary PC Utility v2.3 (Windows 10/11 compatible). The software enables secure download of time-stamped dose logs (1-second resolution), configurable report generation (PDF/CSV), and firmware updates. All stored records include embedded device ID, calibration certificate number, and operator-assigned user tag—facilitating integration into enterprise radiation safety management systems (RSMS). The utility enforces role-based access control and generates tamper-evident audit trails compliant with ISO/IEC 17025:2017 documentation requirements. No cloud synchronization or remote telemetry is implemented, preserving data sovereignty per institutional IT security policies.
Applications
- Routine personal monitoring for radiographers, NDT technicians, and nuclear facility maintenance personnel
- Temporary deployment during decommissioning projects or emergency response drills requiring rapid dose situational awareness
- Verification of shielding integrity in PET/CT suites and linear accelerator vaults
- Educational use in university health physics laboratories for hands-on radiation protection training
- Field screening of scrap metal or construction materials suspected of radioactive contamination
FAQ
Is the BS2010 suitable for neutron or alpha radiation monitoring?
No. The GM tube detector is optimized for photons and high-energy beta particles only. Neutron and alpha detection require specialized proportional counters or scintillation detectors.
Does the device require annual recalibration?
Yes. Per ISO/IEC 17025 and national regulatory guidance, annual traceable calibration against accredited Cs-137 and Co-60 reference sources is recommended. Calibration certificates include energy-dependent correction factors.
Can multiple BS2010 units be managed centrally?
Not natively. Each unit maintains independent local memory. Centralized fleet management requires third-party RSMS integration via exported CSV logs.
What is the minimum detectable dose rate under background conditions?
At typical terrestrial background levels (~0.1 µSv/h), the BS2010 achieves stable readings within ±10% after 60 seconds of integration—consistent with its specified 0.01 µSv/h lower limit.
Is the battery replaceable by the end user?
The lithium-ion cell is sealed and non-user-replaceable. Battery service must be performed by authorized Beigu service centers to maintain IP rating and metrological integrity.
