Summary:The nuclear magnetic relaxation in scandium metal is investigated at liquid helium temeprature for both single crystal and powder samples. The obtained temperature and field dependence of the Korringa constant are described by the means of the spin uctuation theory. It is shown that one of the reason for the high field decreasing of the relaxation rate is the quenching of spin uctuations. The other possible reason is the magnetic impurity influence. The reasons of the existing variations of the Korringa constant are discussed. The possible sources of non-single exponential relaxation are investigated.
