How much does the sun emits in the radio spectrum, compared to artificial (human) emissions?

I would like to compare natural vs artificial (human) emissions in the radio spectrum (f < 1 THz).

The goal is to bring some scientific facts in the debate for deployment of 5G.

It’s easy to find info for the spectrum around visible light :

I am looking for something similar for radio waves, and ideally some measures of the power of equivalent human emissions (radio, 4G, 5G, etc).

Also, I believe that artificial emissions are usually measured in a different units (V/m) and it’s not easy to compare to W/m2/nm.
