By inverting the brightness integral for the dust-scattered continuum, the authors have determined how the dust grains are distributed inside the Orion nebula. The scattering characteristics of the Orion dust at a given wavelength is kept constant within the nebula, and the geometry of the nebula is assumed to have a hemispherical shape. The resulting radial distance dependence of the distribution of dust number density, Nd(r) shows that the dust grains are depleted at the central region of the Orion nebula and concentrated in the region 5arcmin - 6arcmin away from the Trapezium stars. The scattering characteristics of the Orion dust are of moderately forward throwing nature, and the Orion dust has low values of albedo.
