PURPOSE:To decide whether or not the contents of a package are affected and its degree without destroying the package by irradiating the external surface of the package with an ultrasoft X ray and obtaining video information. CONSTITUTION:The package is vibrated by a mechanical means or manually. This vibration disperses the dead space in the package according to the viscos ity, etc., of the contents. The external surface of the package is irradiated with the ultrasoft X ray in this state, and then the video information is obtained. Then the dispersion state of the dead space in the image is observed, and conse quently the dispersion is small when the contents are not affected, but the number of dispersed dead spaces increases according to the degree of the affec tion, thereby easily deciding whether or not the contents are affected and its degree. |
