Spectrometer AT6102

De AT6102 is een spectrometer (nuclide indentifier) die gebruik maakt van een interne NaI detector. Met dit toestel kan snel en eenvoudig radioactiviteit worden gedetecteerd en de nuclide worden geïdentificeerd. Deze radioactieve bronbepaling is belangrijk wanneer het van belang is welke soort activiteit gemeten wordt. Het toestel geeft aan welke nuclide het is en of het een medische, industriële of natuurlijke activiteit betreft. Het toestel meet ook het stralingsniveau van de radioactieve bron.
