Bureau Veritas offers a wide range of radiological testing options using proven technologies operated by our highly experienced staff
Alpha spectrometry is the most sensitive, but also most involved radiochemistry method. It requires sample dissolution and radiochemical separation to isolate the radioisotope of interest. Alpha emitting isotopes are then measured under vacuum by an alpha spectrometer.
This cost-effective method makes use of the characteristic energy signatures of emitted gamma radiation produced during radioactive decay to identify and quantify the radionuclides present in a sample. Gamma spectrometry can determine many radionuclides at the same time.
Gas Flow Proportional Counting
Gas flow proportional counting measures ionizing radiation (alpha and beta particles) using a gaseous ionization detector. . This method is used for general screening of samples (gross alpha and gross beta measurement) or for measurement of specific radionuclides if chemical separations are first performed.
Liquid Scintillation Counting
This method is best for single isotope determination, such as analysis of tritium or C-14.
Neutron Activation Analysis
Neutron activation analysis (NAA) is a highly sensitive, accurate technique used for quantitative analysis of major, minor, and trace elements. This multi-element method is suitable for solids, liquids, gases, mixtures and suspensions, requiring no, or minimal sample preparation. Neutron activation analysis has application in quality control programs testing for high purity, difficult matrices, and geological samples.
