INDUSTRIAL IRRADIATORS

DESIGN & OPERATION OF INSTALLATIONS – DOSE CALCULATIONS – PROCESS SIMULATION & OPTIMISATION

APPLICATION EXAMPLES IN THE INDUSTRY

USE RAYXPERT OR CALL OUR EXPERTS

Different technologies allow today to use ionizing radiation (RX, Co60, electrons, …) for Industrial applications.
The implementation of these technologies requires an in-depth analysis of the irradiated sample from the radiation protection and to the dosimetry point of view.

STERILIZATION & POLYMERIZATION BY IONIZING SOURCE

SIMULATE THE QUALIFICATION STEPS – Standard ISO 11 137

  • Project management studies
  • 3D modeling of Co60, X-ray and electron beam irradiators
  • Product modeling and materialssetting (density, composition)Irradiated packages movement simulation
  • Operational Qualification and Performance Qualification processes simulation
  • Comparison of dosimetric measurements with the simulation and validation of the tool

OPTIMIZE YOUR PROCESSES

Conveyors path and sources positioning to improve:

  • The homogeneity of the total deposited dose in a package (differents between min and max)
  • The average dose rate

 

NON-DESTRUCTIVE CONTROL

PREPARE YOUR ON SITE INTERVENTIONS

  •  3D modeling of the intervention area
  • Source configuration (X-ray scanner, Gammagraphy, etc.)
  • Dosimetry assessment during maintenance interventions (site zoning)
  • Study of the need for collective protection
  • Implementation of an intervention scenario

PRODUCT QUALIFICATION

PREDICT THE LIFETIME OF AN EQUIPMENT

  • Activation calculations related to protons, deuterons, neutrons
  • 3D modeling of the irradiator and the product
  • Product material setting (density, composition)
  • Determination of the irradiation position according to the desired dose rate
  • Attenuation calculation when shielding is required
  • Calculation of source decrease
  • Calculation of the dose deposited in a material or electronic component

ELEMENTS QUANTIFICATION

SIMULATE THE OPERATION AND CALIBRATE YOUR DEVICES

  • 3D modeling of the environment to be quantified
  • Environment material setting (density, composition)
  • Source setting (Gamma & Neutron probe, Germanium counter …)
  • Particle counting
  • Comparison with measurements

INSTALLATION DESIGN & MODIFICATION

  • 3D modeling of the environment to be quantified
  • Project management studies
  • Intervention at different stages of the architectural project
  • 3D modeling of nuclear buildings / installations (BNI)
  • Proposal for radiological zoning
