Physics Research

The components of these detectors are also available individually for purchase, such as ASICs, preamps and more, for when you don’t need a full detector solution.

Furthermore, if you or your team are building a device from scratch or have a custom system in the works, a variety of our detectors and their components can be incorporated into them. Many of these detectors are also drone-mountable, suitable for large area mapping surveys or for access into unsafe target sites.

Additional spectroscopy software is also available for you to achieve the accurate, in-depth spectral analysis you need to measure your chosen variables.

User Stories

Range of Integratable Detectors

The GR1 family of CZT detectors can be easily incorporated into your own devices or custom systems to achieve your specific research goals.

Watch the video for a short introduction to each member of the GR1 family.

As self-contained detectors, GR1 detectors contain all the components you need to complete in-depth spectral analyses of your chosen radioactive sources, by-products or neutron activation foils:

  • Preamplifiers
  • Shaping amplifiers
  • Baseline restorer
  • Pulse height digitizer
  • HV supply

Take the GR1 and its high resolution anywhere

Powered via USB, the GR1 detectors transmit the digitised pulse heights of detected gamma ray signals straight to your PC. Therefore, as long as you have a GR1 and a PC or tablet, you can take your research anywhere, even up Mount Everest!

The high efficiency and <2.5% resolution of the GR1 also ensures the spectral data you collect is accurate with clearly distinct spectral peaks. In the instance you need an even higher resolution, the GR1+ offers a resolution of <2%.

Even though the GR1 is only 1cm3, it can still give you large area coverage of your target research area, or, testing site when mounted on a drone. This is also possible with the even smaller GR05. Its maximum dose rate of 10mSv/hr is optimal for completing research in high flux environments such as Fukushima.

Add an analogue output to that please

The GR1-A is just like the GR1, with the exception of 3 MCX connectors. These provide analogue energy and timing outputs as well as gate inputs.

Additionally, MultiSpect Analysis gamma spectroscopy is already integrated into the GR1-A. Therefore, there’s no need to stretch your budget for extra analytical software.


Higher capacity gamma and neutron detectors

Although they have a lower resolution than the GR1, the TN15 thermal neutron detector and SIGMA 25/50 gamma detectors are slightly larger in size. However, like the GR1, they are self-contained, operational at room temperature, compact and complete with a USB output. As a result, TN15 and the SIGMA detectors so can be just as easily integrated into your own devices, mounted onto drones or used as standalone devices for radiation detection and isotope identification.


We don't just do off-the-shelf detectors

Here at Kromek, we provide end to end solutions, manufacturing our detectors and their components from the ground up.

Radiation Mapping with Drones

When your target research area is large, difficult to access or potentially dangerous, send in the AARM drone borne solution.

At Bristol University, they did just this! Watch the video to find out what the team got up to in the famous Red Forest, Chernobyl.

The AARM payload, with its universal gimble, small size and weight is simple to attach to the fixed-wing or rotary UAV drone model of your choice. Also, due to its small size, when flown into tight spots, there is minimal risk of damage to the drone, detectors or infrastructure being surveyed. A choice of either the GR1, SIGMA 25/50, TN15 or D3S ID are incorporated into the AARM payload. This ensures you collect radiological data for the specific variables you need to measure e.g. isotope ID, counts per second overtime, dose estimation or location of counts per second with identified radiation hotspots.

Additional environmental data can be collected along repeated flight paths from several supporting sensors. This allows for consistent data collection and the ability to monitor changes in an area overtime. The environmental variables include: position fixing by multi GNSS, height above mean sea level, laser ranging to determine height above the surface, temperature, time, date and more.

Extra Secure Data Collection

When your research or equipment tests are confidential, the encrypted one-to-one communication of the AARM Lite ensures no one can intercept your data. Radiation data is accurately collected via a paired D3S ID, GR1 or SIGMA 50. This is integrated in real-time into a radiation map on the IOS AARM Lite app. As a result, during your large area survey, different radiation intensities, anomalies and hotspots are clearly mapped out from background radiation. Live feed and thermal imaging is also possible with the gimbal camera, to further support you in pinpointing the exact location of a radioactive source.

Furthermore, the AARM Lite exclusively pairs with the DJIM300 drone model. As the most advanced model on the market, it functions effectively in any environment and in extreme weather. Operating from up to 15km away, the AARM Lite puts your safety first.

Gamma Spectroscopy Software

With data collection comes data analysis. Download our simple-to-use spectroscopy software ‘KSpect’ to analyse your specific sources by completing spectral acquisitions, energy calibrations and identifying multiple regions of interest. Any spectra can be saved in a variety of formats and files needed for reporting and then easily exported.

If you already have KSpect downloaded, or need to measure some extra variables, upgrade your software to the more advanced MultiSpect Analysis (MSA). Using this spectroscopy software, isotope ID can be attained in real-time with a user configurable library of over 400 radionuclides. Connect multiple detectors to KSpect at one time to converge all your data and analyse it at one time in one place. With MSA, no radionuclide is likely to remain unidentified in your sample, or be lost in the analysis.

MSA is compatible with several Kromek detectors, and comes already integrated with the GR1-A. However, it is also possible to use it with non-Kromek detectors with the K102 Multichannel analyser. Simply connect your chosen detector to KSpect or MSA via the USB port in your laptop or desktop.

Quantify your samples

In the instance you need to take quantitative measurements of your radioactive samples, you need the Quant 4 RayMon10 or the Quant 4 GR1. Your point or distributed sources of air, waste, food, water, building material, geological material or something else entirely, can all be quantified with accuracy and confidence.

As an all-in-one identification and reporting device, the Quant 4 RayMon10 makes quantitative analysis as simple as possible. Reports can be generated from the extensive library of radionuclides, with all those present quickly identified and listed. The Quant 4 RayMon10 is operational straight out of the box with pre-set efficiency calibrations and pre-calculated geometric fixtures using its own radbeaker. Complete your analysis and reports directly on site with no need for any other device.

Also avoid any unwanted spectrum shifts with the stabilised CZT probe. Any variations in normal operating conditions won’t affect your results.

Need Custom Efficiency Calibrations?

Although the Quant 4 RayMon10 can’t complete custom efficiency calibrations, the Quant 4 GR1 can.

In the field or as a bench top lab, use the Quant 4 GR1 to generate custom efficiency calibrations using your own beakers, fixtures and reference sources. Moreover, with a copper-lined lead shield, the contribution of background radiation is minimised to ensure your data is as accurate as possible. This is especially significant when conducting experiments or research in higher does environments with mixed sources. Quantify the radioactivity of any radioactive sample with a count spectrum range of 4096 channels.
