Opis

Przyrząd wyskokiej czujności i małego rozmiaru, dla wykrywania, lokalizacji oraz identyfikacji materiałów radioaktywnych i jądrowych według ich zewnętrznego promieniowania gamma i neutronowego oraz amplitudowego widma promieniowania gamma. SPECTRA identyfikuje radionuklidy z zaznaczeniem kategorii, do której one należą (zgodnie z wymaganiami MAEA). Stosuje się w celu zapobiegania ich bezprawnemu przemieszczeniu przez granice państwowe, a także na przedsiębiorstwach i w urzędach, w których wykonują prace ze źródłami promieniowania gamma i promieniowania neutronowego.

Nowy algorytm poszukiwawczy zabiezpiecza wysoką czujność przyrządu i natychmiastowe uruchamianie przy najmniejszej zmianie poziomu tłowego gamma czy neutronowego. Scyntylator z fotopowielaczem krzemowym nowego typu zabiezpiecza wysoką stabilność temperaturową przyrządu, a także całkowicie wuklucza „efekt mikrofonowy”.

Przyrząd jest nadzwyczajnie wygodny w użyciu dzięki jego malym rozmiarom, dużemu kolorowemu wyświetlaczu i możliwości ciąglej pracy przez ponad 200 godzin w stanie włączonym.
