This section describes calibrated single and mixed radionuclide
sources in different geometries for the energy and efficiency
calibration of gamma-ray spectrometers. A range of sources
simulating different samples, for example, charcoal filters
and gas standards, is also shown. If a reference source is
needed to match your particular sample, please specify your
requirements using the request form in this section.
Applications:
High resolution gamma-ray spectrometry is widely used for
identifying and assaying gamma-ray emitting radionuclides
in environmental samples. To meet the requirements of quality
management systems, the spectrometers should be calibrated
using reference sources that are traceable to national standards.
The reference sources must also match as closely as possible
the geometry, density and composition of the sample to be
assayed. This range of ready-for-use geometry reference sources
has been developed to meet these requirements.
The advantages of this type of source are:
- No source preparation needed - saves time and resources
- No dilution of solutions needed - calibration is traceable
to national standards
- No dispensing of strong acids for dilution is needed
- Sealed source - no risk of contaminating sensitive equipment
- Stable source - will not deteriorate over time
- Source checked for homogeneity - consistent, accurate, results
year after year
- Matches closely the samples to be measured - can be prepared
in your own container with a wide range of densities from
gas equivalent to cement
- Wide range of commonly used beakers or bottles available
- Custom geometry - to meet your special requirements
