What is nuclear radiation detector - Huaqiang Electronic Network

Nuclear radiation detectors, also known as radiation detection devices, are essential tools used to measure and monitor levels of ionizing radiation. There are different types of radiation alarms available in the market. One common device is the radiometer, which provides a simple indication of whether the current radiation level exceeds safety standards but does not display the actual dose. In contrast, a radiation dose detector offers more detailed information by displaying the exact radiation dose at a given location.

The core component of a nuclear radiation detector is the Geiger-Müller tube. This component allows the device to detect various forms of ionizing radiation, including alpha, beta, gamma, and X-rays. Due to this capability, some manufacturers refer to these devices as X-ray dose alarms or X/Y-ray dose alarms, depending on their specific applications.

Key specifications of the detector include:

• Detector Type: Geiger-Müller tube with energy compensation
• Effective Diameter: 1.75” (45mm)
• Mica Flake Density: 1.5–2.0 mg/cm²

Detection Capabilities:

• Alpha, Beta, Gamma, and X-ray

Display: High-definition digital LCD display

Average Period: The device updates the display every 3 seconds, with a 30-second average under normal conditions. The average period shortens as the radiation intensity increases.

Measuring Range:

• mR/hr: 0.001 – 110.0
• μSv/hr: 0.001 – 1100
• CPM: 0 – 350,000
• CPS: 0 – 5,000
• Total/Timer: 1 – 9,999,000 counts

Sensitivity: 3500 CPM/mR/hr referenced to Cs-137

Response Thresholds:

• Alpha: ≥ 2.0 MeV
• Beta: ≥ 40 keV
• Gamma: ≥ 10 keV

Accuracy: ±10% to ±15%

Alarm Settings:

• Sv/hr: 0 to 500
• mR/hr: 0 to 50
• CPM: 0 to 160,000
• Sound Level: 70dB @ 1m

Indicator Light: A red LED flashes once per detected count (each ionization event).

Timer Function: Customizable from 1 minute to 40 hours (in 1-minute increments).

Sound Alarm: Internal buzzer (can be turned off for silent operation).

Output Ports: CMOS/TTL mini jack for connection to computers or data loggers. A submini jack allows for electronic calibration.

Power Supply: 9V alkaline battery. Under normal use, it lasts approximately 2000 hours at 1 mR/hr, and up to 700 hours at higher radiation levels.

Operating Temperature: -20°C to 50°C

Dimensions: 150 x 80 x 30 mm

Weight: 272g (without battery)
