SVHD (/W) Intelligent Ultra High Dose Probe

SVHD (/W) Intelligent Ultra High Dose ProbeIt is a high-performance detector designed specifically for nuclear retirement and underwater applications. Its dose rate measurement capability enables safe and accurate navigation in complex environments, ensuring reliable performance. The SVHD (/W) probe is capable of measuring dose rates up to 1000 Sv/h and can withstand cumulative doses of up to 5 kSv. The probe offers two configurations: SVHD/W (waterproof type) suitable for spent fuel pool detection, and SVHD (standard type) optimized for small space dismantling tasks, both supporting plug and play functionality and can be quickly integrated into third-party systems.

1. High dose rate measurement: capable of measuring the equivalent value of H * (10) dose rate from 1 mSv/h to 1000 Sv/h.

2. High cumulative dose: has a long service life and can withstand cumulative doses up to 5 kSv.

3. Multiple configurations: SVHD/W: used for underwater fuel inspection, IP68 rating, waterproof to 8 atmospheres (in boron water).

SVHD: Used for dismantling and decommissioning tasks, IP64 rating, with a diameter of only 11 mm, making it easy to pass through shielding plugs.

4. Simple deployment: The compact design of the probe (with a diameter of 11 mm) is highly suitable for use in 15 mm ducts and S-shaped shielded intersections with a diameter of 65 mm and a radius of 400 mm.

5. Easy to install and quick to use: The detector/cable assembly can be disconnected from a remote electronic box for easy installation through shielding, and can be replaced with similar spare parts when the detector reaches cumulative dose. After replacing the detector, recalibration is required.

6. Plug and play function: After calibration, the probe can be used as a plug and play device to initiate quality assurance measurements (rem/h or Sv/h), depending on the area settings of the instrument.

7. Compatibility with third-party systems: can be easily integrated into other systems.

1. Display unit: Sv/h, Sv or rem/h, depending on the connected instrument. The equivalent value of H * (10) environmental gamma dose rate complies with ICRP60 standard.

2. Source of emission: Gamma rays

3. Detector: Energy compensated silicon diode

4. Energy range: Gamma energy range is 65 keV to 1.3 MeV, with an error range of -29% to+67%, and an angle range of 0 ° to ± 45 °,Compliant with IEC 60846 standard.

5. Sensitivity: 22 c/s per mSv/h (137Cs) or 45 μ Sv/h/c/s

6. Measurement range: 1 mSv/h to 1000 Sv/h (100 mrem/h to 100000 rem/h), with an error range of -15% to+22% below 400 Sv/h and ± 30% between 400 Sv/h and 1000 Sv/h.

7. Response time:<2 seconds (initial value 1 mSv/h changes by 10 times)

<4 seconds (initial value 0.1 mSv/h changes by 10 times)

<30 seconds (with a 10 fold change between the initial value of 10 μ Sv/h and 100 μ Sv/h)
