PROBLEM TO BE SOLVED: To provide an RFID tag, a tag reader/writer, a data management system and a data management method which can prevent the occurrence of an data error and can be functioned normally in a special environment where the tag is exposed to radiation. SOLUTION: The RFID tag includes an antenna which is disposed at a multi-layer so as to be communicable with the outside. The multi-layer has a shielding member shielded from radiation, and an RFID circuit is arranged in the multi-layer so as to be covered with the shielding member so that the occurrence of the data error in the special environment can be suppressed.

PROBLEM TO BE SOLVED: To provide a sheet of radiation shielding safety glass, suitable for use in radiographic examination in a medical facility, which does not scatter sharp pieces when broken and therefore is safe, which is superior in visibility over a long period of time, and which is light. SOLUTION: A piece of radiation shielding safety glass 10 is obtained by joining cover glass plates 10b to both sides of a radiation shielding glass plate 10a with a resin layers 10c sandwiched therebetween, respectively. Each of the cover glass plates 10b is composed of glass containing a composition with a total amount of alkali metal oxides of ≤2% by mass percentage of oxide conversion and having a density of 3 , and has a thickness of 50 to 1,000 μm.

PROBLEM TO BE SOLVED: To provide a radiation protection device for a vehicle that is extremely compact at normal times, does not require space for storage, can be extremely easily attached to the vehicle in a short time to prevent immersion of the radiation once an event occurs, and allows fast movement when the vehicle approaches a radiation generation source and when it escapes. SOLUTION: The radiation protection device comprises a transparent first shielding member 3 that is disposed so as to fully cover a glass section 2 of a vehicle body 1 facing the radiation generation source G and shields the radiation, supporting members 6 and 10 for supporting the first shielding member 3, a second shielding member 20 that is disposed so as to fully cover a side section 4 of the vehicle body 1 facing the radiation generation source G other than the glass section 2 of the vehicle body 1 and shields the radiation, and a holding member 21 for fixedly holding the upper end of the second shielding member 20 to the vehicle 1.

PROBLEM TO BE SOLVED: To provide an X-ray imaging apparatus that has the equivalent shielding capacity as lead shielding with a relatively simple configuration and has reduced leaked X rays, and to provide a relatively lighter X-ray imaging apparatus than the conventional one by reducing a ratio of occupation by a shielding member. SOLUTION: The X-ray imaging apparatus comprises an X-ray generation source for applying X rays, an object to be inspected by applying X rays, and an X-ray sensor being arranged at the opposite side to the X-ray generation source of the object to be inspected. The shielding section made of tungsten or barium salt is provided at least at a section where the X-ray sensor is arranged.
