Bringing the lab to the field

The Environmental Protection Agency of Romania brought high resolution spectral analysis from the lab into the field with the RayMon. They have been able to successfully monitor contamination in air, soil and water, and reliably characterising environmental radioactivity on site, such as TENORM.


The Environmental Protection Agency of Romania have deployed the RayMon gamma spectrometer to complete spectral analysis directly in the field. The National Reference lab for Radioactivity have used this highly portable and easy to use device to monitor radioactive contamination in air, soil and water, it high resolution enabling the reliable characterising TENORM. This key capability of in situ spectroscopy will continue to facilitate measurements in emergency or requested interventions.

HPGe: a great spectroscopic device until…

A frequently used tool in Gamma spectroscopy are High-purity Germanium (HPGe) detectors, their significantly high resolution producing precise spectral peaks for reliable spectral analysis.

However, HPGe detectors are large, physically fragile and expensive, requiring specialist knowledge and, most of all, cryogenic cooling to operate.

So, what happens when you urgently need to take in situ measurements and your HPGe system is not cooled down?

When and why is in situ analysis important?

Being able to complete full spectral analysis in field saves time and money without the need for transporting radioactive samples to and from the field and lab.

Conducting sample analysis and radiation monitoring in the field is an significant capability for organisations such as the Environmental Protection Agency (EPA) of Romania. Regularly monitoring various environmental factors such as air, soil and water, the EPA can:

  1. Inform strategic environmental strategy
  2. Authorise activities with potential environmental impact
  3. Enforce legislation and policy
  4. Produce reports for the European EPA to summarise findings on air quality, climate change, protected areas, soil contamination and water quality

In situ measurements are necessary for identifying whether a target site is contaminated with radiation, especially with respect to classifying TENORM (Technologically Enhanced Naturally Occurring Radioactive Material). TENORM refers to naturally occurring radioactive materials whose concentrations or levels of exposure to the natural environment have been enhanced by human activity e.g. mining, energy production, water treatment and certain consumer products.

Uncovering the identity of such contaminants is also essential in emergency situations to appropriately inform next steps in remediation.

Saving time and money with the RayMon

Highly portable and easy to deploy when needed, the RayMon gamma spectrometer has proven to be a ideal tool for the National Reference lab for Environmental Radioactivity.

The device has been used successfully to complete routine in situ measurements and exercises to monitor possible radioactive contamination in air, soil and water. The aptly high resolution and sensitivity of the CZT Probe connected the RayMon tablet has facilitated the reliable characterisation of environmental radioactivity, including TENORM.

As a result, the RayMon will continue to be used in scenarios where in situ spectroscopy is required, such as in emergency or requested interventions.
