<P>PROBLEM TO BE SOLVED: To provide a device for taking a radiation image capable of taking radiation images of different energy bands and further capable of reducing influence on radiation having penetrated through an object. <P>SOLUTION: In a device 1 for taking a radiation image according to the present invention, there is provided dual energy imaging for taking radiation images of different energy bands with a surface detector 3 and a rear surface detector 4. Due to no interposition of imaging means between an object A and a wavelength conversion plate 6, the influence on radiation having penetrated through the object A is reduced and radiation of a low energy band is appropriately detected. Furthermore, scintillation light collected by the surface detector 3 and the rear surface detector 4 is emitted in the direction forming angles θ<SB POS="POST">1</SB>, θ<SB POS="POST">2</SB>to respective normal lines B, C. Therefore, similar perspectives are generated in radiation images Pa, Pb and calculation between images of the incidence surface 6a side and a rear surface 6b side can be easily performed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
