Brief introduction

Gardiner-S&TradioactivityQuick verification software for waste activity measurement results，MainlyapplicationYu DuiSGS（segmentationγScanning device)andTGS（chromatographyγScanning device) ofγVerification of radioactive activity measurement results，It can also be applied to other applicationsγradioactive wasteactivityVerification of measurement results.

SGSandTGSquiltNuclear power plants, reprocessing plants, decommissioned nuclear facilities, etc. are widely used for barrel loading radioactive materialsgood-for-nothingγradioactivityMeasurement,Measurement results often lack validation, and userspsychologicallyThere's no bottom either.Gardiner-S&Taccording toSGSorTGSofmeasurement result，countWaste binThe surrounding dose field, and thenSGSandTGSdeviceComparison of measurement results of matching dose rate instruments,as well asCompare and verify the measurement results with high-purity germanium detectorsactivityIs the measurement result correctreliable，giveThe error range of the measurement results.

• counttime：Gardiner-S&T-Dless than1minute，Gardiner-S&T-MCless than5minute；
• countAccuracy: less than5%；
• adaptScope of waste bins: WasteliquidLung resin, wastecotton fabric、Waste filter elementWaiting for waste bins, also applicable to cement solidification bins；
• ModelingThe modeling data is sourced fromin advanceKnowledge of density measurement results, transmission source measurement results, etc，The software pre sets the bucket model, and when using it, the user calls different bucket models and inputs information such as the material density of the current bucket；
