Can you tell which radioactive elements are in it from the spectrum?
Yes, the gamma emission peaks correspond to specific transitions of excited nuclear states or to processes such as the annihilation of an electron and a positron.
The app has a built-in database of common decay chains, so I can click on a peak and lines are drawn at the positions that correspond to the radioactive chain. In this spectrum one can see primarily the lines from the decay of radium-226 and its products lead-214 and bismuth-214
Here is a labeled spectrum I found at https://www.gammaspectacular.com/blue/ra226-spectrum :
