Bromine (₃₅Br) has two stable isotopes, ⁷⁹Br and ⁸¹Br, and 35 known radioisotopes, the most stable of which is ⁷⁷Br, with a half-life of 57.036 hours.

Like the radioactive isotopes of iodine, radioisotopes of bromine, collectively radiobromine, can be used to label biomolecules for nuclear medicine; for example, the positron emitters ⁷⁵Br and ⁷⁶Br can be used for positron emission tomography.^[4]^[5] Radiobromine has the advantage that organobromides are more stable than analogous organoiodides, and that it is not uptaken by the thyroid like iodine.^[6]
