I thought it was fifteen isotopes, but if the first answer is taken from a more recent book, then I must be out of date. Probably showing my age and memory.

The fifteenth edition of "Nuclides and Isotopes" lists 18 known isotopes for scandium beginning with Sc-39 and ending with Sc-55. Only Sc-45 is naturally occurring. The longest-lived isotope is Sc-46 with a half-life of 83.81 days. It decays by beta minus.
