Nuclear Radiation Detector Geiger Counter with Energy-Compensated GM Tube

This nuclear radiation detector is a handheld Geiger counter made for checking ionising radiation from beta, gamma, and X-ray sources. It uses an energy-compensated GM tube and provides a measuring range of 00.00 to 99.99 μsv/h, with a stated sensitivity of 80cpm/μsv/(Co-60). The unit offers real particle sound, alarm sound, or mute, and the alarm threshold can be set to 0.5, 1.0, 2.0, or 5.0. Power can come from an AA dry battery, a rechargeable battery, or USB. The ABS engineering plastic shell measures 135 x 70 x 38mm and weighs 180g without batteries. It is supplied in a choice of black or white.

Features and Construction

The detector combines a GM tube sensor with a compact ABS housing and flexible power options. It is intended for users who need a simple handheld radiation tester rather than a fixed installation. The stated detection types, measuring range, and alarm settings are the key facts to compare against a given task.

Sensor and Detection Type

The energy-compensated GM tube is the core sensor. It supports detection of beta, gamma, and X-ray radiation. Sensitivity is given as 80cpm/μsv/(Co-60). This matters because the tube type and stated sensitivity are the basis for the readings the device can provide, and they set the detector apart from simpler units that do not list a tube type or sensitivity figure.

Measuring Range and Alarm

The measuring range runs from 00.00 to 99.99 μsv/h. Alarm thresholds can be selected at 0.5, 1.0, 2.0, or 5.0. A choice of real particle sound, alarm sound, or mute is available, so the user can hear activity, rely on an alarm, or work silently as needed. These settings relate directly to how the detector is used in day-to-day monitoring.

Uses and Placement

Because it is handheld and battery or USB powered, this radiation tester can be used in different locations. It is not limited to a single site. The working environment covers -25°C to +45°C with relative humidity up to 95% at +45°C, which supports use in a range of indoor and outdoor conditions within those limits.

Event or Professional Use

The detector is suitable for checking radiation around equipment, stored materials, or work areas where beta, gamma, or X-ray sources may be present. The selectable alarm threshold allows the user to set a level that suits the task, and the real particle sound gives audible feedback during checks. The ABS shell protects the internal parts during routine handling.

Everyday Home Use

For home or general interest use, the device can be carried by hand and switched to mute when discretion is needed. It uses readily available AA dry battery, rechargeable battery, or USB power, so it can be kept ready for occasional checks. The black or white finish is a simple visual choice rather than a technical difference.

Benefits and Buying Value

This product offers practical value through its stated detection capabilities, selectable alarm levels, and flexible power supply. It does not require a permanent installation, and the ABS housing keeps the unit light enough to hold at 180g without batteries.

Reuse and Low Maintenance

The detector is designed for repeated use with AA dry battery, rechargeable battery, or USB power. No specialist maintenance instructions are supplied, so care should be based on keeping the ABS shell clean and dry and following the stated working environment of -25°C to +45°C and relative humidity ≤95% at +45°C. The package contains one detector.

Why Choose This Product

Choose this Geiger counter if you need readings in μsv/h across a 00.00-99.99 range, with an energy-compensated GM tube, beta, gamma, and X-ray detection, and selectable alarm thresholds at 0.5, 1.0, 2.0, or 5.0. Its 135 x 70 x 38mm ABS body, 180g weight without batteries, and black or white colour options make it a compact handheld option.
