The self-consistent generation of type III radio emissions and their morphological features has been an open problem since the 1950s. Using data from the Parker Solar Probe, namely the radio frequency spectrometer (RFS) to analyze type III fine structures (striae) and link them to the statistical properties of density fluctuations from 13 to 60 solar radii obtained using the floating potential technique. We find that the average level of density fluctuations decreases with distance from the Sun, while the intermittency is high at the characteristic scales of the striae. Our findings demonstrate that the probabilistic model of beam-plasma interaction describes, step by step, the self-consistent generation of type III radio bursts, from the excitation of Langmuir waves to electromagnetic wave emission.
