Definitions
- the invention relates to a radiation protection molded body and its use.
- the object of the present invention is to provide a molded radiation protection body to create from a lead base body, which has a high flexibility has without bending in the surface of the radiation protection molded body Cracks appear.
- the radiation protection molded body have a smooth surface on which after decontamination no contaminated particles remain on the plates; next to one
- the radiation protection molded body is said to have high corrosion resistance with a Touch by workers in no way to damage them lead and it should also not cause health damage come.
- the radiation protection molded body consists of a bendable plate made of a square, rectangular or of a different geometric shape and from one Lead base body, the lead base body of the plate-shaped Shaped body to prevent corrosion of the lead plate surface and to create a smooth plate surface on one or both sides a cover layer applied or glued by roll cladding is made of tin or a tin-containing alloy.
- the plate-shaped radiation protection molded body is available as a single plate or side by side - and / or one above the other - lined up on frame frames kept used.
- the lead body of the radiation protection molded body by a covering layer of tin or a tin-containing alloy has a smooth, pore-free and self-contained Surface, which results in good decontamination. contaminated Particles no longer remain on the after decontamination.
- Surface of the molded radiation protection body The on the surface of the Lead base body applied covering layer of tin or a tin-containing Alloy prevents bending or bending of the Radiation protection molded body a crack formation in the molded body surface, so that there is no corrosion of the lead of the base body.
- the with radiation protection moldings according to the invention in Even the lead of the body does not come into contact in contact, but only with the covering layer of tin or one tin-containing alloy, this cover layer being a kind of protective layer forms.
- the cover layer prevents direct contact between the workers with the lead of the base body of the radiation protection molded body. This ensures a high level of occupational safety than when touched no contact is made with the radiation protection molded body with the hands with the lead of the body.
- the one on the lead body applied tin layer or layer of a tin-containing alloy is due to the roll plating made in the surface of the Lead body pressed in, so that no areas susceptible to corrosion be created.
- the tin-containing alloy of the plating layer of the composite material preferably consists of the following composition: sn 0.15 to 0.85% sb 0.05 to 0.15% Cu 0.03 to 0.06% Bi 0.01 to 0.10% Other admixtures: max. 0.10% pb Rest.
- the invention also provides the use of flexible plates made from a square, rectangular or other geometric shape and from a lead base body with a covering layer of tin or a tin-containing alloy applied on one or both sides with a covering layer applied by roller plating or attached by gluing as a plating layer as a radiation protection molded body for shielding against the action of artificial ionizing radiation and for preventing corrosion of the lead base material and for avoiding direct contact of workers with the lead base material.
- the bendable plates used here have, inter alia, a tin-containing alloy, this tin-containing alloy of the plating layer of the composite material consisting of the following composition: sn 0.15 to 0.85% sb 0.05 to 0.15% Cu 0.03 to 0.06% Bi 0.01 to 0.10% Other admixtures: max. 0.10% pb Rest.
- the radiation protection molded body according to the invention 10 from a flexible plate 11 from a square, rectangular or another geometric shape Cutting.
- This cut of the radiation protection molded body 10 consists of a lead base body 20 with its side wall surfaces 20a, 20b.
- This Lead base body 20 is preferably on one or both sides with a cover layer 30 applied or glued by roll plating made of tin or an alloy containing tin.
- the cover layer 30 is made of tin or one tin-containing alloy glued to the lead base body 20.
- the adhesive layer is designated 60.
- this plating layer 40 On the lead base body 20 of the radiation protection body 10, a or on both sides a plating layer 40 'made of tin or a tin-containing one Alloy or from a lead plate or foil 25 and tin or a tin-containing alloy applied, this plating layer 40 'forms the cover layer 30.
- This cover layer 30 can also encase the lead base body 20 on all sides.
- the radiation protection molded body 10 for example on a frame can be attached to form a radiation protection wall the radiation protection molded body 10 with at least one suspension opening 21 provided.
- the radiation protection molded body 10 has two suspension openings 21, which is preferably provided in the upper region of the plate body are.
- the suspension opening 21 is preferably 21 other geometrical shapes are circular are possible.
- the covering layer 30 extends on the lead base body 20 to the wall area delimiting the suspension opening 21 21a, so that corrosion protection also in the area of the suspension opening 21 is given for the lead of the base body 20.
- a tin plating layer 40 'applied on one or both sides which consists of tin or an alloy containing tin.
- 6 and 7 is the structure of the radiation protection molded body 10 or a composite material 40 with a lead-containing tin-plated on one or both sides Basic material, i.e. Lead base body 20 shown, in which a plate or foil-shaped lead material on one or both sides with a plating layer 40 'is connected.
- the plating product on which the plating layer 40 'is based consists of a lead plate 25 onto which a coating 50 of tin or a tin-containing alloy is plated on one side, so that ultimately the tin and the lead are mechanically welded to one another.
- a plating product produced in this way is rolled down to plating thickness and the plating layer 40 ′ thus obtained is plated on one or both sides of the lead base body 20 such that the lead layer of the plating product comes to lie on the lead base body 20.
- the lead base body 20, on which the plating product or the plating layer 40 'is plated preferably consists of a tin-containing alloy, which is composed as follows: sn 0.15 to 0.85% sb 0.05 to 0.15% Cu 0.03 to 0.06% Bi 0.01 to 0.10% Other admixtures: max. 0.10% pb Rest.
- Both the plating layer 40 'and the lead body 20 can be very thin layers.
- the percentages relate to percentages by weight, based on the total weight.
