• ISO 11929

Integrated MCA control + data acquisition + analysis in one platform Powerful automation scripting (“Jobs”) for repeatable workflows Supports up to 250 detectors over network (LAN integration) Advanced uncertainty calculation and detection limit (MDA) analysis Flexible reporting with customizable templates and database integration

GammaVision is a comprehensive, high-performance gamma spectroscopy software platform designed for accurate identification and quantification of radioactive materials. Widely recognized as the industry standard for gamma spectrum analysis, GammaVision combines advanced analytical algorithms with an intuitive interface, enabling users to perform complex measurements with confidence and efficiency. Unlike basic MCA software, GammaVision is built for full analytical workflows, including:

• Energy calibration

• Efficiency calibration

• Peak identification and fitting

• Activity calculation with uncertainty

• Detection limit evaluation (MDA)

At its core, the software uses robust peak search and fitting methodologies, including:

• Mariscotti peak detection

• Library-driven peak matching

• Multiplet peak deconvolution (overlapping peaks)

These capabilities allow accurate analysis even in complex spectra, such as:

• Mixed radionuclide samples

• Low-activity measurements

• Overlapping gamma peaks

GammaVision also incorporates extensive correction models, including:

• Background subtraction

• Coincidence summing correction

• Geometry and attenuation corrections

• Decay corrections during and after acquisition

The platform supports automated workflows via scripting (“Jobs”), ensuring consistent measurement procedures across operators—critical for regulated environments such as nuclear facilities and quality-controlled laboratories. With integrated quality assurance (QA), reporting, and security features, GammaVision is ideal for organizations requiring defensible, auditable, and standards-compliant results.
