A number of radiogenically produced dysprosium isotopes have been studied by in-source laser spectroscopy at ISOLDE using the Resonance Ionization Laser Ion Source (RILIS). Isotope shifts were measured relative to $^{152}$ Dy in the $4f^{10}6s^{2}~^{5}I_{8}$ (gs) $4f^{10}6s6p~(8,1)^{0}_{8}$ (418.8 nm $_{rm VAC}$ )resonance transition. The electronic factor, , and mass shift factor, M, were extracted and used for determining the changes in mean-squared charge radii for $^{rm 145m}$ Dy and $^{rm 147m}$ Dy for the first time.
