Our software is designed to cover
all high precision gamma, scintillation and alpha spectrum analysis requirements
in radiation protection, nuclear medicine, research, industry and training.

GAMMA-W and Gamma-W for Windows are software packages for the high precision analysis of gamma-ray spectra from HPGe and Ge(Li) detectors. The programme is especially noted for its accurate and reproducible analysis of small peaks even on high background regimes.

SODIGAM and SODIGAM for Windows is the only software available on the market for high precision analysis of spectra from scintillation (e.g. NaI(Tl)) detectors. SODIGAM has many features that one finds normally only in programs for the quantitative high-precision analysis of HPGe spectra. Thus SODIGAM is the powerful equivalent to a high precision HPGe gamma -ray spectrum analysis package, and yet it is very simple to use.

ALPS and ALPS for WINDOWS provides high precision analysis of alpha spectra from gridded ionisation chamber and semiconductor detectors (Surface barrier, PIPS, ULTRA and other ion-implanted detectors). It is especially noted for its ease of use and for its ability to accurately deconvolute very closely lying peaks such as the peaks from the ²³⁹Pu and ²⁴⁰Pu multiplet.

SIPPING: S-Online and INCORE are software packages for the online measurement and analysis of spectra from reactor core rod sipping (i.e. the measurement of beta activity in the water surrounding fuel rods and in the degassed air from primary coolant water.) These programmes are customer specific developments for AREVA NP (formerly SIEMENS Nuclear Power GmbH, KWU)

Segmented Gamma Scanner (SGS) is a software package for the fully automatic measurement of segments from a 20 litre barrel containing trans-uranium waste. The system determines the contents of uranium, plutonium, and americium isotopes in the barrel down to the 10mg level. The programme is a customer specific development for Paul Scherrer Institute (PSI).

Whole body counter (GKZ) is a software package for the operation of a whole body counter comprising of up to five NaI(Tl) detectors and/or a HPGe detector. The programme manages personal data of the patient, normalises spectra to each other and calculates isotopic contamination to very low levels.

NucMan is a WINDOWS based software package for the management of nuclear libraries. It contains a database of 1,554 nuclides with 31,266 gamma-ray entries. This database provides the basis for the generation of task-specific user libraries for spectrometry applications. The data are from the second edition of the “Catalog of Gamma-Rays from Radioactive Decay, Part I and II”, Reus and Westmeier. (Other Software)

Comparisons of several commercially available software packages
 for gamma and alpha spectrum analysis have been carried out by the IAEA : 
M. Blaauw et al, "The 1995 IAEA intercomparison of gamma-ray spectrum analysis software",
Nuclear Instruments and Methods in Physics Research A 387 (1997) 416-432.

The Dr. Westmeier GmbH also develops customised software
for your specific applications of nuclear spectrometry.
