The Westmeier Gamma-Ray Spectrometry Systems are state of the art software-controlled PC-based units specifically designed for measurements in high precision environmental applications, education and training, overview survey of unknown
samples, survey of low- and high-radioactivity wastes, nuclear medicine departments, radiological clinics, waste disposal units, sewage effluents which contain radioactive materials, as well as for research and
industrial applications.
There are two basic spectrometer designs to cover all measurement requirements:
for the quantitative measurement of higher activity levels and simple spectra from samples containing only a few nuclides.
for measuring sources at very low activity levels (such as mBq/kg) or when very complex spectra from mixtures of many
nuclides are to be expected. Detection limits of HPGe systems are for identical sample sizes and counting times typically a factor of 15 lower than those of NaI(Tl) systems.
Both systems include modern detectors, low background lead shielding, and the most modern PC plug-in analysers which
completely replace external NIM electronics and which are controlled by software rather than by knobs and buttons. High
-precision analysis software packages containing all algorithms needed for the quantitative analysis of nuclides from singlet or complex multiplet peaks are the key to the success of the systems.
