{{Kotak info isotop niobium}}
'''[[Niobium]]''' ('''<sub>41</sub>Nb''') yang terbentuk secara alami hanya terdiri dari satu [[isotop]] [[Isotop stabil|stabil]], <sup>93</sup>Nb; oleh karena itu, niobium adalah [[unsur monoisotop]] dan [[Unsur mononuklida|mononuklida]]. [[Radionuklida|Radioisotop]] yang paling stabil adalah <sup>92</sup>Nb dengan [[waktu paruh]] 34,7 juta tahun. Isotop niobium dengan umur terpanjang berikutnya adalah <sup>94</sup>Nb (waktu paruh: 20.300 tahun) dan <sup>91</sup>Nb dengan waktu paruh 680 tahun. Ada juga [[Isomer nuklir|keadaan meta]] <sup>93</sup>Nb pada 31 [[Elektronvolt|keV]] yang waktu paruhnya 16,13 tahun. Dua puluh tujuh radioisotop lainnya telah dikarakterisasi. Sebagian besar memiliki waktu paruh kurang dari dua jam, kecuali <sup>95</sup>Nb (35 hari), <sup>96</sup>Nb (23,4 jam) dan <sup>90</sup>Nb (14,6 jam). [[Peluruhan radioaktif#Mode peluruhan|Mode peluruhan]] utama sebelum <sup>93</sup>Nb yang stabil adalah [[penangkapan elektron]] dan mode utama setelahnya adalah [[Peluruhan beta|emisi beta]] dengan beberapa [[emisi neutron]] yang terjadi pada <sup>104–110</sup>Nb.

Hanya <sup>95</sup>Nb (35 hari) dan <sup>97</sup>Nb (72 menit) dan isotop yang lebih berat (waktu paruh dalam detik) yang merupakan [[produk fisi]] dalam jumlah yang signifikan, karena isotop lainnya dibayangi oleh isotop stabil atau berumur sangat panjang ([[Zirkonium-93|<sup>93</sup>Zr]]) dari unsur sebelumnya, [[zirkonium]] dari produksi melalui [[peluruhan beta]] dari [[Produk pembelahan atom|fragmen fisi]] yang kaya neutron. <sup>95</sup>Nb adalah [[produk peluruhan]] dari [[Zirkonium-95|<sup>95</sup>Zr]] (64 hari), jadi hilangnya <sup>95</sup>Nb dalam [[bahan bakar nuklir bekas]] lebih lambat daripada yang diperkirakan dari waktu paruh 35 hari. Sejumlah kecil isotop lain dapat diproduksi sebagai produk fisi langsung.
