Yeah, crazy stuff. Shows what's possible if you have no boundaries. He collected old glow in the dark paint and extracted the radium from it then used beryllium foil to make a neutron source that he used to irradiate thorium from kerosene lamps, producing U-233. Very tiny amounts, but remarkable nonetheless.
