↑  mSe –  Isomer nuklir tereksitasi.
↑  ( ) –  Ketidakpastian (1σ) diberikan dalam bentuk ringkas dalam tanda kurung setelah digit terakhir yang sesuai.
↑  # –  Massa atom bertanda #: nilai dan ketidakpastian yang diperoleh bukan dari data eksperimen murni, tetapi setidaknya sebagian dari tren dari Permukaan Massa (trends from the Mass Surface, TMS).
↑  Waktu paruh tebal –  hampir stabil, waktu paruh lebih lama dari umur alam semesta.
1 2  # –  Nilai yang ditandai # tidak murni berasal dari data eksperimen, tetapi setidaknya sebagian dari tren nuklida tetangga (trends of neighboring nuclides, TNN).
