Radiological characterization activity of a reactor pool of a nuclear research reactor.
The decommissioning of both research and power nuclear plants necessarily requires the radiological characterization of the structures, plants and components during all the phases of dismantling and management of materials, whether they are radioactive or not.
The characterization activities are essential during operations both for the protection of workers, the popultaion and the environment.
The reactor pool is a particularly complex structure from a radiological point of vies both due to the phenomena of neutron activation and to accidental events or leakage that cause contamination of the structures.
LBS provides radiological characterizazion services of plants by carrying out non-destructive in situ measurements and radiochemical measurements at its accredited laboratory.
Radiological characterization activity of a plant for the production of electricity from renewable sources.
For practices that involve the use of radionuclides of natural origin, the operator, within twelve months of the entry into force of Legislative Decree 101/2020, measures the concentration of activity on the materials present in the production cycle or on the residues deriving from the work activity itself.
LBS provides radiological characterization services of plants by carrying out non-destructive in situ measurements and radiochemical type measurements at its accredited laboratory.
Radiological characterization of implant components.
The LBS, thanks to the use of portable HPGe instrumentation and calculation methods based on Monte Carlo simulation, is able to carry out gamma spectrometry measurements on plant components of various shapes and sizes even outside its own laboratory.
Radiological characterization of industrial plants.
Through the analysis of the industrial process, the LBS is able to identify potentially critical situations for the radiation protection of the worker.
Our highly qualified staff is able to offer a complete radiological characterization service of industrial plants, through the use of advanced devices in the detection of ionizing radiation.
Radiological characterization of radioactive waste.
The LBS, thanks to the use of portable HPGe instrumentation and calculation methods based on Monte Carlo simulation, is able to perform gamma spectrometry measurements on radioactive waste of various shapes and sizes such as oil drums, metal scrap and plant components also outside your laboratory.
Measurements of Radon concentration in the soil.
The emanating power of Radon also depends on the characteristics of the soil. It is present in traces in the subsoil almost everywhere.
Its concentration in the soil can vary from a few hundred to more than one million Bq / m³. The instrumentation of which the LBS is equipped allows to make instantaneous measurements of Radon in the environments, in the soils and in the waters.
Alpha particles, released from the Radon gas, on the PADC trace detector
The CR39 system consists of a diffusion chamber, or container, and a nuclear trace detector.
The diffusion chamber allows only radon to enter, not its decay products.
The sensitive element consists of a trace detector of PADC, an organic polymer with the commercial name CR-39. The detector consists of a plate of dimensions 25 × 25 mm and thickness of 1.50 mm.
In the two images acquired with an optical microscope, the traces of the alpha particles released by the radon gas following the development process (Etching) are visible.
From the traces it is possible to estimate the concentration of radon gas in a monitored environment for a specific period of time.
