Interference v gamaspektrometrii
V následujícím seznamu jsou uvedeny možné interference, které teoreticky mohou nastat při vyhodnocování na gamaspektrometrických aparaturách s vysokou rozlišovací schopností . Protože je teoreticky těchto možností velmi mnoho, jsou uvedeny jen ty radioizotopy, které mají poločas větší než 1 den a pravděpodobnost výskytu větší než 0,01. Velikost energetického okna je zvolena na 5 keV.
