Research on the failure reasons of the cooling tube were carried out by means of macroexamination, thickness measurement, X ray diffraction, optical microscopy and chemical analysis.
Results According to the chest X ray film findings,pulmonary tuberculosis was mostly locating in upper and middle lobes,its property included patching effusion shadows,creber tuber...
The crystal structure has been determined by X ray single crystal diffraction, showing a distorted trigonal bipyramidal configuration with five coordination for the central tin atom.
But the visible light we're able to see is only a tiny chunk of the full electromagnetic spectrum, which ranges from short gamma and X rays all the way to long radio waves.
They tried using a complex X-Ray machine at a hospital but the images they got still weren't conclusive enough to declare the painting a true Van Gogh.
First, people guessed that the fogging was caused by the radioactive element radium, since it could trigger and expose X-Ray films if it managed to get into the package.
