[0004] [Patent Document 1] Patent Publication No. 2013-076694 Summary of the Invention [Problem to be solved by the invention]

[0005] However, the protective clothing described in Patent Document 1 uses a heavy radiation shielding material in the inner layer of the fabric that covers the entire body of the worker, and when the protective clothing is worn for a long time, the inside of the protective clothing becomes steamy, causing a decrease in the work efficiency of the worker and a foul odor. Protective clothing containing radiation shielding materials is difficult to wash, and the protective clothing needs to be replaced after use, so there has been a demand for washable protective clothing. In addition, particularly in medical settings, conventional protective clothing that covers the entire body is not convenient, and there has been a demand for protective clothing that workers can put on and take off in a short time.

[0006] SUMMARY OF THE PRESENT EMBODIMENT An object of the present invention is to provide a protective jacket that can be easily washed by a worker and can be put on and taken off in a short time. [Means for solving the problem]

[0007] In order to achieve the above-mentioned object, the inventors conducted intensive research and as a result discovered a radiation protection jacket that protects a wearer from exposure to radiation, the radiation protection jacket comprising: an outer part constituted by a surface and a lining of the radiation protection jacket, the outer part and the lining being configured to provide an internal space, an inner part that is disposed in the internal space and has a radiation shielding plate, and connecting parts that are disposed on the outer part and the inner part, respectively, and the outer part and the inner part are detachably connected to each other at the connecting parts, thereby arriving at the present invention.

[0008] According to the radiation protection jacket of the present invention, the outer part and the inner part are detachably connected at the connecting part, so that the wearer can remove the outer part after using the radiation protection jacket and wash it.

[0009] The radiation protection jacket of the present invention may be a radiation protection jacket characterized in that the connecting portion is a hook-and-loop fastener.

[0010] According to the radiation protection jacket of the present invention, the connecting portion can be a hook-and-loop fastener, so that the wearer can more easily remove the outer portion of the radiation protection jacket after use and wash it. Effect of the Invention

[0011] According to the present invention, it is possible to provide a protective jacket that can be easily washed by a worker and can be put on and taken off in a short time. [Brief description of the drawings]

[Diagram 3] FIG. 1 is a front view of one embodiment of the present invention. [Figure 4] FIG. 1 is a front view of one embodiment of the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Note that the embodiment shown below is an example for embodying the technical idea of ​​the present invention, and the present invention is not limited to this example. In addition, the configurations and processing functions described in the above embodiment can be selected and combined as desired, and it is self-evident that a person skilled in the art can adopt modified forms based on the technical idea and teaching of the present invention.

[0014] The terms "outside," "inside," "front," "rear," "upper," "lower," "right," and "left" used in this specification all refer to directions as seen from the wearer wearing the protective clothing. That is, based on the center of the wearer's body, "outside" refers to the external space side, "inside" refers to the wearer side, "front" refers to the wearer's abdomen side, "inside" refers to the wearer's back side, "upper" refers to the wearer's head side, "lower" refers to the wearer's feet side, "right" refers to the wearer's right arm side, and "left" refers to the wearer's left arm side.

[0015] FIG. 1 shows a radiation protection jacket 1 worn by a wearer.

[0016] As shown in Fig. 1, the radiation protection jacket 1 is configured so that the outer fabric 11 is located on the outside. The radiation protection jacket 1 has an open front configuration so that the right and left ends overlap when worn. In the radiation protection jacket 1, the belt 101 is disposed near the wearer's abdomen and is configured so that its length can be changed according to the wearer's waist circumference. The belt 101 is fastened when worn.

[0017] As a modified example of the radiation protection jacket of the present invention, the left and right ends of the radiation protection jacket may be fastened by buttons or a zipper instead of the belt 101. Also, instead of the front opening configuration as in this embodiment, a hole may be provided in the center, through which the wearer puts their head to wear the jacket, and the jacket may be configured like a poncho that covers the upper half of the body.

[0018] FIG. 2 shows the radiation protection jacket 1 as viewed from the inside relative to the wearer's body.

[0019] As shown in FIG. 2, the radiation protection jacket 1 is provided on the lining 12 with a pair of fasteners 102, 103, an opening 104, and a hook-and-loop fastener 105a.

[0020] A pair of fasteners 102, 103 extend in the up-down direction on the left and right sides of the radiation protection jacket 1. An opening 104 is provided at the lower end of the pair of fasteners 102, 103. A hook-and-loop fastener 105a is provided above the opening 104. When worn, the hook-and-loop fastener 105a and a hook-and-loop fastener 105b provided at the lower end of the inside of the outer fabric 11 are adhered to each other, so that the opening 104 is closed.

[0021] FIG. 3 is a diagram showing the state of radiation protection jacket 1 when hook-and-loop fastener 105b is peeled off from hook-and-loop fastener 105a and the pair of fasteners 102, 103 is opened from opening 104. As shown in FIG.

[0022] As shown in FIG. 3, the radiation protection jacket 1 has an outer part 10 composed of an outer fabric 11 and a lining 12, an inner part 20, and an internal space 30 defined by the outer fabric 11 and the lining 12 of the outer part 10, and the inner part 20 is disposed in the internal space 30.

[0023] FIG. 4 is a diagram showing the left end of the inside of the lining 12 of the outer part 10 and the left end of the inner part 20. As shown in FIG.

[0024] As shown in Figures 3 and 4, three hook and loop fasteners 106 are arranged in the vertical direction at the left end of the inside of the lining 12. Also, three hook and loop fasteners 206 are arranged in the vertical direction at the left end of the inner part 20 so as to correspond to the hook and loop fasteners 206. When worn, the hook and loop fasteners 106 and the hook and loop fasteners 206 are bonded to each other, thereby placing the inner part 20 in the internal space 30. A similar configuration is also present at the right end of the inside of the lining 12, and the inner part 20 is fixed by both ends of the inside of the lining 12.

[0025] Such a radiation protection jacket 1 is made of an outer part that is fastened with hook-and-loop fasteners 106 and 206. Since the outer part 10 and the inner part 20 are configured to be detachable, only the outer part 10, which is easily soiled, can be washed.

[0026] In a modified example of the radiation protection jacket of the present invention, the connecting portion (hook and loop fasteners 106, 206) between the outer part and the inner part may be formed in any other known manner as long as the outer part and the inner part are detachable. For example, instead of the hook and loop fastener, the connecting portion may be formed by a button or a zipper.

[0027] The outer part of the present invention can be made of polyester fibers such as polyethylene terephthalate, polytrimethylene terephthalate, polybutylene terephthalate, etc.; polyamide fibers such as nylon 6, nylon 66, etc.; polyimide fibers, acrylic fibers, polyolefin fibers such as polypropylene, polyethylene, etc.; synthetic fibers such as polyurethane fibers; natural fibers such as cotton, hemp, etc.; regenerated fibers such as rayon, etc.; semi-synthetic fibers such as acetate fibers, etc.; and since the radiation protection jacket of the present invention is particularly prone to becoming stuffy, it is preferably made of polyester fibers and polyamide fibers.

[0028] A radiation shielding plate (not shown) is provided in the inner portion 20. The radiation shielding plate is formed by dispersing fine particles of a simple substance or compound having a high shielding ability against α-rays, β-rays, and γ-rays in a thermoplastic resin as a shielding material.

[0029] Examples of the shielding material include heavy metals such as lead, antimony, bismuth, and tungsten. These shielding materials can be used alone or in mixtures. Among them, antimony, bismuth, and tungsten, which are lighter than lead and lead compounds, can be preferably used since the radiation shielding plate constitutes a part of the radiation protection jacket.

[0030] The radiation shielding plate used in the embodiment of the present invention is a mixture of two attenuating elements, antimony and tungsten. Lead vinyl, which is commonly used for radiation shielding plates, has a mass 32% larger than that of the mixture of antimony and tungsten.

[0031] (K-Edge technology) Antimony efficiently attenuates the photon spectrum below the lead K-edge window (35-88 keV). Tungsten efficiently attenuates high energy radiation (>69 keV). Thus, a mixture of antimony and tungsten can be used to provide a radiation shield that attenuates a wide range of the photon spectrum.

[0032] As the thermoplastic resin, a resin having excellent strength can be preferably used, and rubber, elastomer, etc. can be preferably used. For example, as the rubber, chloroprene rubber, silicone rubber, ethylene propylene rubber, acrylonitrile butadiene rubber, styrene butadiene rubber, etc. can be exemplified, and among them, chloroprene rubber is more preferable. As the elastomer, polyester-based, polyolefin-based, and silicone-based thermoplastic elastomers can be exemplified.

[0033] In the radiation shield used in the embodiments of the present invention, a mixture of finely powdered and encapsulated antimony and tungsten is uniformly dispersed and supported within a matrix of DowDuPont thermoplastic elastomer.

[0034] The radiation shielding plate of the present invention is used as a member constituting the inner part, and therefore is required to have flexibility that allows it to deform in response to the wearer's movements. In addition, since the inner part of the present invention is used repeatedly, it is required to have toughness, durability, and crack resistance. By adopting a configuration in which the shielding material is uniformly dispersed and supported within the thermoplastic elastomer matrix, it is possible to provide a radiation shielding plate that has a good balance between toughness, flexibility, durability, and crack resistance.

[0035] Since the X-ray transmittance of the radiation shielding plate is suppressed to 20% or less, it is useful as a material for the radiation protection jacket of the present invention. In the present invention, the lower the X-ray transmittance of the radiation shielding plate, the better, for example, 10% or less is preferable, and 5% or less is more preferable.

[0036] (Consideration of environmental impact) The radiation shielding plate according to the embodiment of the present invention does not use lead as a shielding material, and the thermoplastic resin does not have a cross-linked structure or a hardening process, so that it can be recycled by being reprocessed by heat treatment, etc. Furthermore, it can be easily disposed of as a non-hazardous, non-toxic waste.
