A new analysis of inclusive quasielastic electron-scattering data for 3He is presented. Integrated momentum distributions are derived from the data for the first time and the Q^2 dependence is shown to exhibit a slight deviation from the perfect scaling. If this is interpreted as a change in the nucleon radius, a result for the ratio of the nucleon radius in 3He to the free-nucleon radius of 1.025 ± 0.011 is obtained, corresponding to an upper limit of 3.6% for the radius increase.
