Calibration of individual electron energies and dose distribution exiting a dipole magnet perpendicular at the dispersive plane was performed using a collimated scintillating fiber based detector. The dipole was constructed from two 5.08x5.08x2.54 cm$^{3}$ permanent magnets separated by a distance of 2 cm and having a maximum filed of about 5 kG. A 1 cm diameter collimated electron beam exiting a $^{90}$Sr/Y radioactive with a 25 $\mu $Ci activity and a 2.28 MeV maximum energy was placed at the entrance face of the magnet. Mapping of the magnetic field was done using a Hall probe with an accuracy of about 2 G. The electron detector consisted of blue shifted scintillating fibers with thicknesses of 1 mm. The setup provides an energy resolution of about 10{\%}. This system will be used to study the differential response of cancer cell irradiation to selected energies. We will present results and discussed the results obtained from this work.
