X-Ray Spectrography Kindergarten.
This article is a continuation of "X-Ray Microscopy Kindergarten.".
Preliminary experiment with multi-energy x-ray (colour channel combination), distinguishing materials by absorption at different wavelengths.
The tube appears to exhibit some "heel effect" at the longer wavelengths.
Exposure: 75 sec. @ 35kV, 21kV, 20kV (R, G, B) film: "Eco-30".
