Portable spectrometers
for radionuclide identification


We supply portable instruments capable of identifying radioactive materials by analysing their characteristic gamma radiation spectra.



NUCSCOUT Portable Radionuclide Identifier

NUCSCOUT portable radionuclide identifier

The NucScout monitors local dose rate as well as the activity of up to 28 user-selectable nuclides. Results are displayed as a time distribution over the entire sampling period. The sampling interval can be adjusted by the user, and a complete energy spectrum is stored for each interval on the internal memory card.

The unit is equipped with an integrated GPS receiver that allows geographic correlation of the recorded data.

The instrument includes a ZigBee wireless network interface for transferring recent data over several hundred metres to a base station computer.

NUCSCOUT gamma radiation spectrum

The robust 2" × 2" NaI detector is mounted on an ergonomic handle, while the electronics unit can be detached from the handle via a bayonet coupling. This allows the user to position the detector independently with respect to the radiation source. A sample table is available for operation with Marinelli beakers. The large detector volume provides a low detection limit, making it possible to detect even weak sources. The large touchscreen display enables comfortable operation and ensures clear visibility of results and spectra even in bright sunlight.

PM1401K-3 Multipurpose Radiation Monitor / Radionuclide Identifier

PM1401K3 radiation detector and radionuclide identifier

The PM1401K-3 is a compact and lightweight instrument capable of operating as a radionuclide identifier, a search and detection unit, an environmental radiation meter, an alarm monitor, and a surface contamination monitor.

All sensors are built into a single IP65-rated housing. The data is displayed on a bright, easy-to-read LCD screen. A belt clip and automatic operating mode enable hands-free use of the device.

Its non-volatile memory stores up to 10,000 events and 1,000 gamma spectra, with data transfer via a USB port. The instrument also includes a built-in GPS receiver.

Optional accessories include a telescopic extension tube, tripod and Marinelli beakers (for measuring Cs-137 activity in water, food and other samples).

The PM1401K-3 multipurpose radiation monitor is available in three versions:


PM1401K model versions

  • PM1401K-3M: includes alpha, beta and gamma radiation detectors, but no neutron detection capability (download PM1401K-3M technical brochure).
  • PM1401K-3P: includes alpha, beta, gamma and neutron detectors based on three scintillation sensors (download PM1401K-3P technical brochure).
  • PM1401K-3E: includes gamma and neutron detectors but does not include Cs-137 activity measurement or radionuclide identification functions.

The PM1401K-3 is capable of performing a wide range of functions:

· Radionuclide identification (PM1401K-3M/3P):
The scintillation (CsI) sensor analyses the gamma emission spectrum characteristic of the radionuclide to enable identification.

· Radioactive material search (PM1401K-3M/3E/3P):
The high sensitivity of the solid scintillation sensor enables the detection and localisation of radioactive sources, including shielded ones.

· Measurement of alpha and beta surface contamination (PM1401K-3M/3E/3P):
A Geiger-Müller sensor detects and measures alpha and beta radiation from surfaces contaminated with radioactive material.

· Measurement of gamma dose rate (PM1401K-3M/3E/3P):
Ambient gamma dose rate is measured using the internal Geiger counter.

· Detection of neutron emissions (PM1401K-3E/3P):
A neutron sensor enables the detection of special nuclear materials such as plutonium and uranium.

· Measurement of specific activity of Cs-137 (PM1401K-3M/3P):
The device determines the specific activity (Bq/kg) of Cs-137 in water, food and environmental samples.
