Pristine
The relative X-ray analysis of a normal area gave three peaks C, Al, and O. The magnitude of the peaks compared as C > Al > O
Under source (irradiated)
The relative X-ray analysis of a normal area gave three peaks C, Al, and O. The magnitude of the peaks compared as C > Al > O . The X-ray analysis of a dark spot gave C = 0 > Al. Also the darker the spot the more O present.

The relative X-ray analysis of a normal area gave three peaks C, Al, and O. The magnitude of the peaks compared as C > Al > O, also the darker areas gave the same relative C > Al > O.
