Can't find diagram of shots to jfk from conspiracy point of view?

[Bob Prudhomme]

The density of skin (mostly black on an xray) is about 1050 kg/m3.

The density of sand is 1280 kg/m3. (Can't tell you what x ray color that might make, but its closer to black than white)

The density of bone is 1900 kg/m3 (mostly white on an xray)

The density of iron is 2600 kg/m3 (bright white on an xray)

The density of lead is over 11,000 kg/m3.

I sorta doubt that the tiny bright fragments are less dense than the bone upon which they lay.

The matter that makes up bone may have a density of 1900 kg./m3 but, is it porous or solid? Would an x-ray of a rock (sand being merely very small rocks) show up as opaque and bright white, and appear similar to the lead fragments seen in the x-ray?

Cast iron actually has a density of 6800-7800 kg./m3, not 2600. A density of 2600 kg./m3 would be more applicable to aluminum. As we are comparing densities here, should lead have a different appearance in an x-ray than iron? For that matter, gold has a density of 19.3 (19,300 kg./m3) and platinum a density of 21.45 (21,450 kg./m3). Do they appear differently in x-rays than sand, lead and iron?
