EBS beta point sources for measuring instruments

Through LEA, Orano provides EBS beta point sources whose diameter, activity and radionuclide can be adapted to your requirements. Their design incorporates a vacuum-deposited gold coating on each side to optimize measurement efficiency.
    • Adapting the source dimensions to your measurement configuration
    • Selecting the radionuclide and activity suited to your requirements
    • Optimizing the source’s measurement efficiency
    • Using sources whose radiological characteristics are measured with calibrated equipment
    • Planning source replacement according to their metrological lifetime and physical integrity
    • Benefit from three standard geometries featuring a 3 mm active diameter and different overall diameters
    • Adapt the active diameter, overall diameter and activity with configurations available on request
    • Select your radionuclide from catalogue references or options available on request
    • Optimize measurement efficiency with a vacuum-deposited gold coating applied to each side of the source
    • Rely on a design combining two heat-sealed polyester sheets and a steel ring
    • Control radiological characteristics through measurements performed using a calibrated gas-flow proportional counter
    • Simplify source grouping with EBS A and EBS B sets available in several configurations
