Particle accelerators—whether linear or circular (cyclotrons)—are essential tools for the production of radiopharmaceuticals used for diagnostic (PET and SPECT) and therapeutic purposes.
However, the use of these devices generates high-intensity ionizing radiation fields, making rigorous management of radiological protection, shielding design, and operational safety indispensable.
A proper assessment of operating procedures and shielding is essential not only to optimize radiological protection but also to minimize environmental impact and ensure effective management of radioactive waste, especially during facility decommissioning.
Comprehensive Support for Design and Authorization
With a team of Radiation Protection Experts and specialized technicians, LB Servizi provides complete support in the design of facilities equipped with particle accelerators, ensuring that construction complies with regulatory requirements and, above all, that the facility operates safely.
Our expertise covers the entire life cycle of the installation—from initial design through decommissioning and final radiological characterization of the site.
Our services include:
- Design of radiological shielding, ensuring maximum safety for operators and surrounding environments
- Development of operating procedures for optimized and safe use of accelerators
- Preparation of technical and regulatory documentation required for authorization procedures
- Radiological impact assessments, ensuring full compliance with national and European standards
Deactivation and Dismantling Management
Prolonged use of a particle accelerator leads to activation of structural materials, with significant implications for safety and waste management.
At the end of the machine’s life cycle, a Deactivation Request must be prepared—a detailed plan for managing the facility and all associated structures.
LB Servizi manages all phases of this process, including:
- Preliminary analysis of the radiological status of the site, supported by Monte Carlo simulations (MCNP or FLUKA)
- Radiological characterization of systems and structures to determine the distribution and type of activated materials
- Definition of decontamination procedures, enabling safe removal of radioactive contamination
- Final site characterization after dismantling, certifying the absence of residual radiological risks
Advanced Technologies for Radiological Characterization
Thanks to cutting-edge instrumentation and a highly specialized team, LB Servizi ensures effective and safe management of every phase of radiological characterization.
Our methodologies include:
- Monte Carlo simulations to predict the distribution of activated materials inside the facility
- In-field gamma spectrometry for detailed radiation analysis
- Sampling and radiochemical analysis to quantify the radioactivity present
- Preparation of documentation required for the authorization process, including the Dismantling Request
LB Servizi already meets all requirements for recognition as both a National Measuring Body and a Dosimetry Service under former Article 155 of Legislative Decree 101/2020.
Additionally, we offer a wide portfolio of ACCREDIA-accredited tests and measurements (UNI EN ISO/IEC 17025:2018).
