<Prior Art> In a room using a radioactive substance, for example, an X-ray room, it is necessary to completely block the leakage of radiation to the outside. For this purpose, it is necessary to take adequate measures to prevent leakage at the openings such as entrances and exits in addition to the walls and floors of the room. Of course, doors, windows, and other fittings used for the openings are provided with radiation protection measures, but this is not enough, and radiation easily leaks from even a small gap, so the door frame It is important to protect the frame materials such as windows and window frames.

<Problems to be solved by the invention> However, in the above-mentioned conventional type, the thickness of the inner surface of the frame body is 1
Although a lead plate of about 2 mm is attached, this work seems to be easy at first glance, it is extremely difficult in practice, it takes a lot of trouble, and many work defects occur. Because the lead plate is too soft and is not suitable for such work, and when the lead plate is punched along the inner surface of the frame body, the thickness of the lead becomes partially thin and holes are formed. Or
It creates the cause of radiation leakage. In addition, the edge of the lead plate attached to the frame body is extended for a considerable length to protect the frame, and after attaching the frame body on site, this extension reaches the concrete wall. Install and install as you would. However, the extended portion protruding from the frame body is largely deformed during transportation of the frame material, which makes mounting work difficult and causes radiation leakage.

<Means for Solving the Problems> The technical means of the radiation protection frame material of the present invention is an outer frame attached to the edge of the opening, an aluminum frame inner frame, and a lead plate attached to the wooden plywood. And a lead plate around the frame. The inner frame is attached to the outer frame by a method of inserting it in the longitudinal direction and is detachable, and the inner frame has a T-shaped cross section. A loading section is provided, and each of the loading sections is assembled by a method of inserting the shielding plate in the longitudinal direction, and the lead around the frame is formed so as to overlap with the extending section of the shielding plate generated by arranging the shielding plate in a T shape. To install the board.

<Operation> The radiation protection frame material of the present invention has a double frame structure of an outer frame and an inner frame, and can be freely attached and detached. Therefore, the manufacturing is easy, and even when the shape of the outer frame is changed, the same inner frame can be used. Since the lead plate is attached to the plywood, the problem that it is too soft and difficult to work and handle is eliminated. Moreover, since the lead plate is assembled to the inner frame together with the plywood, the work is easy. The shield plate is attached to the inner frame in a substantially T shape,
Since the shielding plate extends out of the frame, the lead plate around the frame can be attached so as to overlap with this extending portion, whereby the leakage of radiation from around the frame can be completely blocked. The radiation from the direction can be reliably and efficiently shielded.

<Example> An example of the radiation protection frame material of the present invention will be described with reference to the drawings. 1 to 3 are used for hinged doors. 1 is an outer frame made of steel. Reference numeral 2 denotes an inner frame made of an aluminum mold material, which is fitted and fixed in the outer frame 1. Inner frame 2 as shown in FIG.
A radiation shield plate 3 is attached to the. The shielding plate 3 is constructed by attaching a lead plate 5 to a wooden plywood 4. The thickness of the lead plate 5 is determined according to the amount of radiation used, but in the case of an ordinary X-ray chamber, it is about 1 to 2 mm. Also, this shielding plate 3
Is manufactured by first attaching the lead plate 5 to the entire surface of the plywood 4 with an adhesive and then cutting the lead plate 5 into the required size.
Even lead plates that are too soft and difficult to work and handle can be solved by lining them with plywood. The cut shield plate 3 is assembled by inserting it into the shield plate loading portion 6 formed in the inner frame 2 from the end.
The loading section 6 is provided with a holding claw 7, and the loaded shielding plate 3 is locked and held by the holding claw 7 so as not to fall off. Since the inner frame 2 is made of aluminum mold material,
It is easy to form such a sectional shape having the loading portion 6. Two shield plates 3 are attached to the inner frame 2 in a substantially T-shape so that radiation from any direction can be shielded. An anchor material 8 is attached to the back surface of the outer frame 1 at an appropriate position. Reference numeral 9 is a lead plate around the frame, which is attached to the opening so as to straddle between the frame material and the concrete wall 10. After the installation of the frame material is completed in this manner, the wall top coat 11 is applied. 12 is a hinged door. In addition, in the case of an entrance and exit such as a hinged door, the frame member is attached to the upper portion of the opening and three sides on the left and right sides, and normally, it is not attached to the lower portion (floor surface).

<Effects of the Invention> The radiation protection frame material of the present invention has an inner and outer double frame structure, and can be assembled simply by fitting the inner frame with the shield plate into the outer frame. Further, the inner frame is simply assembled with a shield plate in which a lead plate is attached to plywood. Therefore, as compared with the conventional method in which the lead plate is attached to the inner surface of the frame material, the work is extremely easy and the manufacturing cost can be reduced. Further, since the lead plate is not hammered in, the lead plate is not punctured or lacking in wall thickness, and radiation protection can be completely performed. Further, in the present invention, since the shield plate is attached to have a T-shaped cross section and the lead plate around the frame is attached so as to overlap with the extending portion of the shield plate, radiation from any direction can be surely shielded and an opening can be formed. Radiation leakage from around the frame of the part can be completely prevented.
