The radiative transfer equation is solved for a generalised disc model of the circumstellar envelope around Ψ Persei to investigate the nature of the long wavelength turndown in the continuum spectrum of Be stars. The flux density and source dimensions at 15 GHz rule out truncation of the circumstellar envelope around Ψ Persei as the cause of the turndown.
