なものであることが必要であった。In general, when radiation is incident on a certain material, the rate at which the radiation passes through the material is 1IkW31. It is known that it is inversely proportional to the magnitude of the absorption coefficient. Lead is the most well-known material with a large mass absorption coefficient and radiation shielding function. Therefore, the effects on the human body such as X-rays ii
Lead plates are usually pasted on the walls of rooms where radiation is used. However, when a lead plate is attached to the entire wall, it weighs a considerable amount, making transportation and installation difficult, and the wall needs to have sufficient strength. Met.

This is because as the area increases, there are more opportunities for contact between each particle of the chlorium salt and AI, Os, and Sin in the basic raw materials, promoting the reaction that produces heavy feldspar. The particle size of the lithium salt should be fine enough to pass through 100 meshes or less.

The slurry-like raw material is taken out and dried, and after drying, it is granulated with net desine to prepare the raw material for radiation shielding tiles.
Next, this raw material was pressed at a pressure of 290 Kg/cm2 to form a 5 m thick tile base.Then, the molded product was placed in an electric furnace at 7°C and heated to 1100°C at the current heating rate.
After raising the temperature to 1100°C for 1 hour, it was allowed to cool naturally in the furnace and the firing was completed. In the tile base molded body, in the early stage of firing, BaCO3 changes to BaO(!: 00

代理人 弁理士内田敏彦The amount of BaO contained in the radiation shielding tile obtained in this way is 0.05 mol, and it is equipped with a 7Ic X-ray generator equipped with an OCu tube that is sufficient to shield radiation such as X-rays. , 30KV, 20mA of voltage and current are applied to generate X-rays, and the generated X-rays 1! r, in the radiation shielding tile mentioned above, and in the damage test, it did not pass through at all. Therefore, such a radiation shielding tile was pasted on the wall of a room where X-rays, etc. are used, and By embedding a radiation shielding material such as lead, it is possible to easily obtain a wall surface that shields X-rays and the like. Also, compared to the case where the entire wall surface is covered with lead plates, transportation of materials and construction work are easier.
For interior tiles with a thickness of A1! OJe 810
Experiments have shown that it is sufficient to add 0.02 mol or more in terms of BaO to raw materials such as clay and rouseki containing 1. Therefore, adding Ba to the basic raw material of the tile does not impair its function as a tile. Rouseki T60 is made using 9 raw materials and 38% clay. Basic raw material vcOa with Rouseki as 57
According to the results of OC, in which tiles were manufactured using raw materials prepared by adding 5% of In both cases, there was a large amount of X-ray transmission.As explained above, from the unexploded FJ4, it is possible to manufacture tiles with a completely new radiation shielding function. Therefore, when this tile is installed on the wall of a room where radiation such as X-rays is used, it will have both the original design effect of the tile and the effect of shielding from radiation.
Convenient 0 Also, constructing such a wall surface is very easy as it can be done just by installing conventional tiles
