<p>PROBLEM TO BE SOLVED: To provide learning materials allowing a user to intuitively and correctly understand properties and shielding method of radiation by using five senses without the need for using an actual radiation source.SOLUTION: Learning materials 4 for radiation shielding include: shielding materials 4 with multiple AR tags 8 disposed therein; a virtual radiation source 5 with the AR tags 8 disposed therein; a virtual detector 6 with the AR tags 8 disposed therein; a workbench 7 with reference AR tags 8 disposed therein; a camera 3 for photographing a working area on the workbench 7; and a computer 1 having a calculation device, a memory device and a display device, and capable of communicating with the camera 3 and the virtual radiation source 5. The computer 1 includes: means for recognizing the reference AR tags 8 from the working area image received from the camera 3; means for recognizing the AR tags 8 of the shielding material 4, the virtual radiation source 5 and the virtual detector 6 as arrangement objects contained in the working area image; means for calculating a radiation track on the basis of the virtual radiation source 6, and reference coordinates and arrangement object coordinate information, and radiation information; and means for allowing the display device to display the strength and/or the number of radiation.</p> |
