We have performed a statistical study of 152 Type III radio bursts observed by Solar TErrestrial RElations Observatory (STEREO)/Waves between May 2007 and February 2013. We have investigated the flux density between 125kHz and 16MHz. Both high- and low-frequency cutoffs have been observed in 60% of events suggesting an important role of propagation. As already reported by previous authors, we observed that the maximum flux density occurs at 1MHz on both spacecraft. We have developed a simplified analytical model of the flux density as a function of radial distance and compared it to the STEREO/Waves data.
