Description

本考案は放射能を有する物質で汚染された物質(以下放射性汚染物とする)が人並びに他の生物への悪影響を与えずに安全に収納一保存する為の容器に関するものである。    The present invention relates to a container for safely storing and storing a substance contaminated with a radioactive substance (hereinafter referred to as a radioactive pollutant) without adversely affecting humans and other living organisms.

今まで放射線を遮蔽する物質に鉛等有りましたが、鉛のみでは容器としての強度が不足していて、なお、他にも日本中で計画されている 地中に穴を掘って厚いコンクリートで囲み埋めこんで排水工事を行うと莫大な工事費もかかり場所も容易に選定できなくて復興が進まない原因でもある    Until now there was lead etc. as a material that shields radiation, but lead alone is insufficient in strength as a container, and there are other plans to dig a hole in the ground and use thick concrete. If drainage work is carried out by burying it, it will be a huge construction cost and it will not be possible to select the place easily, which will also cause the recovery to not proceed

今まで放射能で汚染された物質を人体や生物から隔離するのに鉛以外で覆う方法も有り(例−上記のコンクリ−ト囲み等)ましたが、長く使用する場合コストの面で問題が有った。    Until now, there has been a method of covering with radioactive materials other than lead to isolate radioactively contaminated substances from human bodies and living organisms (eg, the above-mentioned concrete enclosure), but there is a problem in terms of cost when using it for a long time. There was.

1 本考案は安価な鉛を用いて放射線を減量できるものである。図3のように鉛板6(厚さ7mm)を内側に施して外面をFRP7(汎用品ポリエステル系の樹脂で厚さ約3.5mm)で覆い施こす容器にして問題を解決している。この場合フタも同様な構造になっている。1 The present invention can reduce radiation using inexpensive lead. As shown in FIG. 3, a lead plate 6 (thickness 7 mm) is applied on the inside, and the outer surface is covered with FRP 7 (a general-purpose polyester-based resin with a thickness of about 3.5 mm) to solve the problem. In this case, the lid has the same structure.

2 上記の施工にて図1のような放射性汚染物を収納できる角型容器1を製作してその容器1内に低濃度の放射性汚染物を収納−保管できるようになっており、更にこの容器は積み重ねできるようになっていて何段でも積み重ねができる。又、積み重ねされた容器1に土嚢で覆う事で問題を解決している2 A rectangular container 1 that can store radioactive contaminants as shown in FIG. 1 is manufactured by the above construction, and low-concentration radioactive contaminants can be stored and stored in the container 1. Can be stacked and can stack any number of levels. Moreover, the problem is solved by covering the stacked containers 1 with sandbags.

本考案容器1内に低濃度放射性汚染物を収納して前述している手段を施す事により人体(生物)を放射線からの悪影響を無くす事ができる。  By storing the low-concentration radioactive contaminant in the container 1 of the present invention and applying the above-described means, the human body (living body) can be prevented from being adversely affected by radiation.

本考案放射能遮蔽容器の正面図である。  It is a front view of the radiation shielding container of the present invention. 本考案方射能遮蔽容器の平面図である。  It is a top view of this invention method radiation shielding container. 本考案方射能遮蔽容器の側部1部段面図。  1 is a side view of a part of the inventive method shielding container.

本考案の角型容器の側部断面構造は図3のようになっている。容器1内の放射性汚染物から出る放射線を図3は鉛板6(約7mm×1枚)で減量する事が可能である。  The side sectional structure of the rectangular container of the present invention is as shown in FIG. The radiation emitted from the radioactive contaminant in the container 1 can be reduced by the lead plate 6 (about 7 mm × 1 sheet) in FIG.

更に軽くて強く耐食性−耐久性の強いFRP7で覆い固定する事により従来の放射性遮蔽容器より安価で減量できる容器として使用できる。  Furthermore, it can be used as a container that can be reduced in weight at a lower cost than a conventional radioactive shielding container by covering and fixing with FRP 7 that is lighter, stronger, corrosion resistant and durable.

以下添付図面に従って実施例を説明する。図1は本考案放射性遮蔽容器の正面図であり1は角型容器でその上部のフタ2は容器1の出し入れ口1Aの上にかぶさっていてボルト3とナット3Aにて締め付けられている。  Embodiments will be described below with reference to the accompanying drawings. FIG. 1 is a front view of a radioactive shielding container according to the present invention. Reference numeral 1 denotes a rectangular container, and an upper lid 2 is placed on an inlet / outlet 1A of the container 1 and is fastened by a bolt 3 and a nut 3A.

容器1の外側の四隅は支柱(角パイプ)5を4本にて固定できる。  Four pillars (square pipes) 5 can be fixed at four corners on the outside of the container 1.

更に容器1の下部はリフト爪挿入用角パイプ4(2本)が施されられてリフトの爪(2本)が入る大きさでリフトによって爪挿入用角パイプ4にリフト爪を挿入して持ち上げ運搬反転ができる。  Furthermore, the lower part of the container 1 is provided with lift claw insertion square pipes 4 (two pieces), and is lifted by inserting lift claws into the claw insertion square pipe 4 by lift so that the lift claws (two pieces) can be inserted. Transport can be reversed.

容器1を保管する為に支柱5(角パイプ)4本の枠内に入れている。支柱5間は補強パイプ(角パイプ)5A及び補強パイプ5B(小さい角パイプ)で補強されており、容器1が保管されている。なお、容器1下の補強パイプ5Aは縦−横方向(点線で示す)に格子状に施され、更に爪挿入用4の下にも補強パイプ5C(5Aと同寸法の角パイブ)で縦−横方向に格子状に施されている  In order to store the container 1, it is put in a frame of four columns 5 (square pipes). The space between the columns 5 is reinforced by a reinforcing pipe (square pipe) 5A and a reinforcing pipe 5B (small square pipe), and the container 1 is stored. The reinforcing pipe 5A under the container 1 is applied in a lattice shape in the vertical-horizontal direction (indicated by a dotted line), and further under the claw insertion 4 with a reinforcing pipe 5C (a square pipe having the same dimensions as 5A). It is given in a grid in the horizontal direction

図2は上から見た平面図でフタ2をかぶせボルト3とナット3Aで締め付けられている。  FIG. 2 is a plan view seen from above, which is covered with a lid 2 and fastened with bolts 3 and nuts 3A.

図3は図1に示す容器1のA−A’及びB−B’で示す箇所の1部断面図であり鉛板6(厚さ約7mm)は容器1内の低濃度放射性汚染物から出る放射線を減量する事が可能である。更に軽くて強く耐久性の高いFRP7(汎用性ポリエステル系の樹脂で厚さ約3.5mm)で外側を覆っている、この時容器内に入れる現状の焼却灰34ベクレルの場合に鉛6で約16.8ベクレルに減量できる。  FIG. 3 is a partial cross-sectional view of the container AA ′ and BB ′ shown in FIG. 1 where the lead plate 6 (thickness of about 7 mm) comes out of the low-concentration radioactive contaminant in the container 1. It is possible to reduce radiation. Furthermore, it is covered with the light and strong and durable FRP7 (general-purpose polyester resin, thickness is about 3.5mm). Can be reduced to 16.8 Bq.

参考データーReference data

放射線を半減に減量するに要する厚さは、鉛で7〜8mm要に対し、鉄15mm要で、コンクリートでは50mm要となりまして鉛が効果大です。  The thickness required to reduce the radiation by half is 7 to 8 mm for lead, 15 mm for iron, and 50 mm for concrete. Lead is effective.
