Quant 4 GR1

GR1 CZT-based gamma radiation detector with custom efficiency calibrations to identify and quantify any radioactive isotope in the lab or field

High resolution gamma detector for use in raised backgrounds and with mixed sources

The Quant 4 GR1 is a complete, mobile solution for quantifying doses of gamma radiation released by radionuclides. Its high resolution of <2% and count spectrum range of 4096 channels enables any isotope to be identified and its associated dose quantified. This is possible even when isotopes are part of a complex mixture, meaning there is no need for chemical separation. Such analysis can be completed for either point sources from filter paper or distributed sources e.g. soil or liquid samples.

The ability to quantify radiation doses in real time eliminates the need for further analysis in the lab, as any data can be collected and then processed on site, saving time and costs.

The Quant 4 GR1 is much smaller than Germanium-based detectors and processes data at a much faster rate. It is also portable, and requires low power to operate, without the need to cryogenically cool the crystals before use.

Its copper-lined lead shield minimizes the contribution of background radiation to the results, ensuring the data collected is as accurate as possible. This makes the Quant 4 GR1 optimal for research or quick action in the field, especially in higher dose environments with mixed sources e.g. sites of a nuclear accident.

Customisable Efficiency Calibration

The Quant 4 GR1 comes with pre-loaded default settings for efficiency calibrations. These are created using model simulations of the beakers, Maypack filter, filter paper and fixtures that come as part of the Quant 4 GR1 solution package.  There are also pre-loaded energy calibrations with Caesium and Americium as references.

However, if you are an expert in your field, there is the option to conduct your own efficiency calibrations using your own beakers, fixtures and reference sources. This allows you to measure the activity of any radioactive sample of your choosing.

Further versatility is also achieved through its compatibility with GR05 and GR1+ which are also CZT-based detectors from the GR1 family.

Quant 4 Raymon10

Preset calibrations? Good enough for me!

The preset calibrations are also available with the Quant 4 RayMon10 but are not customisable. Therefore, if you are not a scientific expert but still want to conduct research directly in the field without having to set up multiple devices or complete your own calibrations, the Quant 4 RayMon10 may be more suited to your needs.

Supplied with Kromek MultiSpect Analysis Premium

The MultiSpect Premium software is adapted for any application of the Quant 4 GR1, generating isotope ID in real-time. It allows you to view the spectra in full and adjust confidence levels at your leisure. This is where you can utilise the preset efficiency calibrations or generate your own custom.

The GR1 can be connected to a laptop with the software downloaded via its USB port for completion of analysis in-field.  Any files created can be saved for reporting at a later date, and can be exported as CSV or PDF for reports.
