In-Situ Radiological Characterization

When can a site be considered contaminated by radioactivity?
What procedures must be followed to release it from radiological constraints?
How can the safety of personnel and the public be ensured?
Has the site been affected by illegal disposal of radioactive substances?
Do work areas present non-compliant contamination levels?

Answering these questions is essential to prevent risks and ensure compliance with current regulations.
For this reason, LB Servizi provides an In-Situ Radiological Characterization service, allowing the identification and assessment of radioactive contamination through advanced analysis and monitoring techniques.

Radiological Characterization Methodologies

Radiological characterization of an environment can be performed using two complementary approaches:

1. Sampling and Laboratory Analysis

This method is useful for accurately determining the concentration and type of radionuclides present in collected materials.

2. In-Situ Field Measurements

Performed using advanced instrumentation to obtain a direct and immediate assessment of any contamination.

3. By integrating both sets of data—laboratory results and on-site measurements—a complete diagnosis of the radiological status of the area is obtained.

Thanks to this combined approach, LB Servizi can deliver a detailed radiological overview, supporting companies, public authorities, and industry operators in managing issues related to natural or artificial radioactive contamination.

When Radiological Characterization Is Required

The radiological characterization service is essential in several contexts, including:

Remediation of contaminated land, to assess radioactivity levels before, during and after decontamination operations.
Nuclear medicine facilities, to verify the absence of contamination after the use of radioactive materials.
Industrial sites involving NORM (Naturally Occurring Radioactive Materials), such as facilities processing materials containing natural radioactivity.
Process residues and industrial effluents, to monitor and control their radioactivity levels.
Illegal waste disposal, to detect the presence of radioactive substances in suspected locations.

Even seemingly simple industrial operations can generate residues with elevated concentrations of natural radioactivity, becoming a potential environmental and radiological risk.
For this reason, accurate and timely monitoring is essential.

Radiometric Survey
Radiometric survey activities are essential for detecting radioactive sources or contaminated materials that may have been dispersed accidentally or as a result of industrial processes that do not comply with current legal regulations.
This type of mapping helps prevent risks and ensures the safety of the environment, the population, and workers.

In the event of accidental releases, radiometric surveys are crucial for assessing the spread of radioactive contamination in the environment, taking into account dilution and percolation phenomena, as well as biomagnification processes.

Application Sectors

LB Servizi provides support to a wide range of public and private organizations operating in multiple sectors where it is necessary to assess the presence of radioactivity, both under normal conditions and in the event of accidental releases or unexpected findings.
