Description
【０００１】[0001]
本考案は放射線源容器に係り、例えば化学プラント、火力・原子力プラント等 における配管などの被検査物を放射線透過試験により撮影して検査する場合に使 用される放射線源容器に関する。 The present invention relates to a radiation source container, and more particularly to a radiation source container used when an object to be inspected such as a pipe in a chemical plant, a thermal power plant, a nuclear power plant, etc. is photographed and inspected by a radiation transmission test.
【０００２】[0002]
化学プラント、火力・原子力プラント等における配管の突き合わせ溶接継手な どを検査する場合、放射線透過試験が用いられる。このような場合、従来では撮 影のための放射線源に線源移動用ワイヤを取り付け、この線源移動用ワイヤを送 給・引き戻しすることにより、放射線源の位置を調整している。そして、撮影後 は線源移動用ワイヤを引き戻し、放射線源容器内に設けられた鉛ブロックの迷路 と呼ばれる曲がりくねった貫通孔内に放射線源を固定して保管している。 A radiation transmission test is used when inspecting butt welded joints of pipes in chemical plants, thermal power plants and nuclear plants. In such a case, conventionally, a radiation source moving wire is attached to a radiation source for imaging, and the radiation source moving wire is fed and pulled back to adjust the position of the radiation source. After the radiographing, the wire for moving the radiation source is pulled back, and the radiation source is fixed and stored in a winding through hole called a maze of a lead block provided in the radiation source container.
【０００３】[0003]
上述した従来の放射線源容器は、線源に線源移動用ワイヤを取り付けた小さな ものを対象としており、線源容器内の迷路を有する鉛ブロックも比較的小さくて 済むが、放射線源の移動中は遮蔽が施されていないので、広い範囲に放射線が放 射される。従って、被爆を避けるために広い範囲を立ち入り禁止区域にする必要 がある。 The above-mentioned conventional radiation source container is intended for a small one in which a wire for moving the radiation source is attached to the radiation source, and the lead block with the maze inside the radiation source container can be relatively small, but the radiation source Since it is not shielded, it emits radiation over a wide area. Therefore, it is necessary to set a wide area as a restricted area to avoid exposure.
【０００４】 一方、放射線源をシャッタ機能を有するタングステンキャプセル内に設けて線 源ヘッドを構成すると、線源ヘッドが大きくなるため、上述した従来の構成では 迷路を有する鉛ブロックも大きなものとなり、放射線源容器の運搬に支障を来す ことになる。このため、遮蔽体として鉛製の円筒を用いればよい。On the other hand, when the radiation source is formed by providing the radiation source in the tungsten capsule having the shutter function, the radiation source head becomes large, and thus the lead block having the maze also becomes large in the above-described conventional configuration, and the radiation block becomes large. This will hinder the transportation of the source container. Therefore, a lead cylinder may be used as the shield.
【０００５】 しかし、このような構成とした場合には、放射線源の後方は線源ヘッド自体で 十分な遮蔽能力を持たせられるが、前方の遮蔽に関しては遠隔的に遮蔽蓋を開閉 できる構成とする必要がある。また、操作性を考慮すると、遮蔽蓋の開閉の遠隔 操作電動式でなく、機械的な手法により行うことが望まれる。However, in such a configuration, the radiation source head itself has sufficient shielding ability behind the radiation source, but the shielding lid can be opened and closed remotely for the front shielding. There is a need to. In consideration of operability, it is desirable that the opening / closing of the shield lid is performed by a mechanical method instead of a remote operation electric type.
【０００６】 本考案は、このような課題を解決すべくなされたもので、作業中および保管状 態で外部へ放出される放射線量が少なく、しかも操作性の良好な放射線源容器を 提供することを目的とする。The present invention has been made to solve such a problem, and provides a radiation source container which emits a small amount of radiation to the outside during work and storage and has good operability. With the goal.
【０００７】[0007]
上記の課題を解決するため、本考案は被検査物内部に放射線源を挿入して放射 線透過試験を行う際に使用される放射線源容器において、前記放射線源を前方端 側に位置させてシャッタ駆動機構内に収容すると共に、後方端側に送給ホースが 連結可能に設けられた線源ヘッドと、前記線源ヘッドを着脱可能に収容する円筒 状遮蔽体と、前記円筒状遮蔽体の前方端および後方端にそれぞれ着脱可能に設け られた前方外蓋および後方外蓋と、前記円筒状遮蔽体の前記線源ヘッドの直前位 置に開閉可能に設けられた遮蔽用中蓋と、前記送給ホースによって前記線源ヘッ ドが前記円筒状遮蔽体の外部へ送り出されている間は前記遮蔽用中蓋を開放状態 に保持し、前記送給ホースによって前記線源ヘッドが前記円筒状遮蔽体内部へ引 き戻されたとき前記遮蔽用中蓋を閉鎖状態とする閉鎖機構とを具備することを特 徴とする。 In order to solve the above-mentioned problems, the present invention relates to a radiation source container used when performing a radiation transmission test by inserting a radiation source into an object to be inspected. A radiation source head, which is housed in the drive mechanism and has a feed hose connectable to the rear end side thereof, a cylindrical shield which detachably accommodates the radiation source head, and a front of the cylindrical shield. A front outer cover and a rear outer cover which are detachably provided at the end and the rear end, respectively, a shield inner cover which is openable and closable at a position immediately before the radiation source head of the cylindrical shield, The shielding inner lid is held in an open state while the radiation source head sends the radiation source head to the outside of the cylindrical shielding body, and the radiation source head causes the radiation source head to move to the cylindrical shielding body. When pulled back inside That you and a closing mechanism for the lid in for serial shielding and a closed state and Features.
【０００８】[0008]
このように構成された放射線源容器は、放射線源をタングステンキャプセルの ような開閉可能なシャッタ機構内に収容して線源ヘッドを構成しているため、線 源ヘッドは線源を線源移動用ワイヤに直接連結させた従来の場合より形状が大き くなる。しかし、線源ヘッドの収容部は円筒状遮蔽体であるため、撮影後、送給 ホースを引くことにより、容易に線源ヘッドを容器内、つまり円筒状遮蔽体内に 引き戻すことができる。 In the radiation source container configured in this manner, the radiation source is housed in a shutter mechanism such as a tungsten capsule that can be opened and closed to form a radiation source head. Therefore, the radiation source head is used for moving the radiation source. The shape is larger than in the conventional case where it is directly connected to the wire. However, since the accommodating portion of the radiation source head is a cylindrical shield, the radiation source head can be easily pulled back into the container, that is, the cylindrical shield by pulling the feed hose after imaging.
【０００９】 また、円筒状遮蔽体に線源ヘッドを収容する構成をとった場合、放射線源の後 方は線源ヘッド自体で十分な放射線遮蔽能力を持たせる一方、前方側の遮蔽をい かに行うかが問題となるが、本考案では円筒状遮蔽体の線源ヘッドの直前位置に 開閉可能な中蓋を設けることにより、この問題に対処している。すなわち、送給 ホースによって線源ヘッドが円筒状遮蔽体の外部へ送り出されている間は遮蔽用 中蓋を開放状態に保持し、送給ホースによって線源ヘッドが円筒状遮蔽体内部へ 引き戻されたとき遮蔽用中蓋を閉鎖状態とする閉鎖機構を設けることによって、 送給ホースを引くという機械的な操作で遠隔的に遮蔽用中蓋を閉鎖することが可 能となる。遮蔽用中蓋を鉛のような材料で形成すれば、この状態で十分な放射線 遮蔽効果が得られる。Further, when the radiation source head is housed in the cylindrical shield, the radiation source head itself has a sufficient radiation shielding ability while the radiation source head has a shield on the front side. However, in the present invention, this problem is addressed by providing an openable / closable inner lid immediately before the radiation source head of the cylindrical shield. That is, while the radiation source head is being sent out of the cylindrical shield, the shielding inner lid is held open, and the supply hose pulls the radiation source head back into the cylindrical shield. By providing a closing mechanism that closes the shielding inner lid at this time, it is possible to remotely close the shielding inner lid by a mechanical operation of pulling the feeding hose. If the shielding inner lid is made of a material such as lead, a sufficient radiation shielding effect can be obtained in this state.
【００１０】 また、このように線源ヘッドを円筒状遮蔽体内に引き戻した後は、前方外蓋お よび後方外蓋を取り付けることにより、放射線源容器から外部へ放射線が出るこ とは完全に避けられる。Further, after the radiation source head is pulled back into the cylindrical shielding body in this way, by attaching the front outer lid and the rear outer lid, it is possible to completely prevent radiation from the radiation source container to the outside. To be

以下、図面を参照して本考案の一実施例を説明する。 図１は、本考案の一実施例に係る放射線源容器の構成を示す図であり、（ａ） は側面図、（ｂ）は断面図（Ｘ−Ｘ断面図）である。 An embodiment of the present invention will be described below with reference to the drawings. 1A and 1B are views showing the configuration of a radiation source container according to an embodiment of the present invention, wherein FIG. 1A is a side view and FIG. 1B is a sectional view (XX sectional view).
【００１２】 図１において、放射線源１は例えばＹｂ169 ガンマ線源であり、この放射線源 １はこれを収納したシャッタ式タングステンキャプセル２と共に線源ヘッド３を 構成している。線源ヘッド３は、円筒状遮蔽体である遮蔽用鉛円筒４と、遮蔽用 鉛円筒４の前方端および後方端にそれぞれ配置された、鉛板を内部に有する前方 外蓋５および後方外蓋６によって、完全に遮蔽されている。前方外蓋５および後 方外蓋６は、ねじ等により着脱可能に取り付けられている。In FIG. 1, the radiation source 1 is, for example, a Yb 169 gamma ray source, and this radiation source 1 constitutes a radiation source head 3 together with a shutter-type tungsten capsule 2 accommodating the same. The radiation source head 3 includes a shielding lead cylinder 4 that is a cylindrical shield, and a front outer lid 5 and a rear outer lid that have lead plates inside and that are arranged at the front end and the rear end of the shielding lead cylinder 4, respectively. It is completely shielded by 6. The front outer lid 5 and the rear outer lid 6 are detachably attached with screws or the like.
【００１３】 また、遮蔽用鉛円筒４の線源ヘッド３と前方外蓋５との間には、線源ヘッド３ の直前に位置して、鉛板からなる中蓋７が配置されている。この中蓋７は、中蓋 引き上げ棒８によって引き上げが可能となっている。また、中蓋７はばね９で中 蓋７側に付勢された中蓋連結金具１０と接触している。Further, between the radiation source head 3 of the shielding lead cylinder 4 and the front outer lid 5, an inner lid 7 made of a lead plate is arranged in front of the radiation source head 3. The inner lid 7 can be pulled up by an inner lid lifting rod 8. Further, the inner lid 7 is in contact with the inner lid connecting fitting 10 that is biased by the spring 9 toward the inner lid 7.
【００１４】 図２は、図１の矢視Ａ−Ａ断面図であり、中蓋７と中蓋引き上げ棒８の構造を 示している。 次に、図３〜図７を参照して本実施例の放射線源容器の作用を説明する。FIG. 2 is a cross-sectional view taken along the line AA of FIG. 1, showing the structures of the inner lid 7 and the inner lid lifting rod 8. Next, the operation of the radiation source container of this embodiment will be described with reference to FIGS.
【００１５】 図３は、図１および図２に示した本実施例の放射線源容器の前方外蓋５を取り 外して、代わりにフレキシブル連結管１２の一端と一体に結合した前方連結フラ ンジ１１を取り付け、さらに後方外蓋６を取り外して、送給ホース１３の一端に 取り付けたジョイント１４を線源ヘッド３に差し込んだ状態を示している。FIG. 3 is a front connection flange 11 in which the front outer lid 5 of the radiation source container of this embodiment shown in FIGS. 1 and 2 is removed, and instead is integrally connected to one end of the flexible connection pipe 12. Is attached, the rear outer lid 6 is removed, and the joint 14 attached to one end of the feeding hose 13 is inserted into the radiation source head 3.
【００１６】 ここで、前方連結フランジ１１の取り付け作業と、後方からのジョイント１４ の取り付け作業はいずれも素手で行われるが、放射線源１の前方は中蓋７によっ て十分遮蔽されており、後方も線源ヘッド３自身と後方突起部１５の遮蔽効果に よって十分遮蔽されているため、作業者の被爆のおそれは全くない。Here, both the mounting work of the front connecting flange 11 and the mounting work of the joint 14 from the rear are performed with bare hands, but the front of the radiation source 1 is sufficiently shielded by the inner lid 7, There is no danger of the worker being exposed to radiation because the radiation is also sufficiently shielded by the radiation source head 3 itself and the rear projection 15 as well.
【００１７】 図４は、フレキシブル保護管１６に結合した後方連結フランジ１７を本実施例 の放射線源容器１８に連結し、中蓋引き上げ棒８を持ち上げて中蓋７を引き上げ た後、送給ホース１３を矢印方向に送ることにより、線源ヘッド３を送り出した 状態を示している。中蓋７に接触している中蓋連結金具１０は、ばね９で常に前 方、すなわち中蓋７側に押し付けられているため、中蓋引き上げ棒８を持ち上げ ることにより中蓋７を引き上げると、中蓋７の厚さに相当する分だけ前進する。 従って、中蓋７は落下すること無く、線源ヘッド３を送り出している間、開いた 状態を保つ。In FIG. 4, the rear connecting flange 17 connected to the flexible protection tube 16 is connected to the radiation source container 18 of this embodiment, the inner lid pulling rod 8 is lifted to pull up the inner lid 7, and then the feeding hose. The state in which the radiation source head 3 is fed out by feeding 13 in the direction of the arrow is shown. Since the inner lid connecting fitting 10 that is in contact with the inner lid 7 is always pressed forward by the spring 9, that is, the inner lid 7 side, when the inner lid lifting rod 8 is lifted, the inner lid 7 is pulled up. , The amount of movement corresponding to the thickness of the inner lid 7 is advanced. Therefore, the inner lid 7 does not drop and remains open while the radiation source head 3 is being sent out.
【００１８】 図５は、本実施例の放射線源容器１８を用いた放射線試験システム全体の構成 を示しており、放射線源容器１８から離れた位置で操作して送給ホース１３を図 ４で説明したように送り出すことによって、放射線源容器１８を介して線源ヘッ ド３を被検査物である配管１９内に挿入し、配管１９の溶接部の位置にセットし ている。FIG. 5 shows the configuration of the entire radiation test system using the radiation source container 18 of this embodiment, and the feeding hose 13 will be described with reference to FIG. 4 by operating at a position away from the radiation source container 18. By sending out as described above, the radiation source head 3 is inserted into the pipe 19 as the inspection object via the radiation source container 18, and is set at the position of the welded portion of the pipe 19.
【００１９】 この状態で撮影が終われば、送給ホース１３を引っ張り、送給ホース巻き取り ドラム２０に巻き取ることることにより、線源ヘッド３を放射線源容器１８内に 戻すことが可能である。When the photographing is completed in this state, the radiation source head 3 can be returned into the radiation source container 18 by pulling the feeding hose 13 and winding it around the feeding hose winding drum 20. .
【００２０】 図６は、こうして線源ヘッド３を放射線源容器１８内に引き戻した状態を示し ている。送給ホース１３を少し強く引くと、ばね９が縮み、中蓋連結金具１０が 後方に引かれることにより、中蓋７が落下して放射線源容器１８の内部が閉じる ことになる。このように、放射線源容器１８から離れた位置より送給ホース１３ を引くという作業によって、遠隔操作で中蓋７を閉鎖することができる。FIG. 6 shows a state in which the radiation source head 3 is pulled back into the radiation source container 18 in this way. When the feeding hose 13 is pulled a little, the spring 9 contracts and the inner lid connecting fitting 10 is pulled backward, so that the inner lid 7 falls and the inside of the radiation source container 18 is closed. In this way, the inner lid 7 can be closed by remote control by pulling the feeding hose 13 from a position away from the radiation source container 18.
【００２１】 この後、前方連結フランジ１１および後方連結フランジ１７を取り外し、さら に送給ホースジョイント１４を外して、前方外蓋５および後方外蓋６を取り付け れば、放射線源容器は図１に示した保管収納状態となる。After that, the front connecting flange 11 and the rear connecting flange 17 are removed, the feeding hose joint 14 is further removed, and the front outer lid 5 and the rear outer lid 6 are attached. The storage and storage state shown is obtained.
【００２２】 上述した本実施例の放射線源容器に、放射線源１として０．３Ｃｉ（キューリ ー）の容量のＹｂ169 線源を収容して、上述した撮影を含む一連の作業を行った ところ、作業中の被爆線量は全く検出されず、十分な安全性を有していることが 確認された。A Yb 169 radiation source having a capacity of 0.3 Ci (Curie) was housed as the radiation source 1 in the radiation source container of the present embodiment described above, and a series of operations including the above-mentioned imaging was performed. No exposure dose was detected during the work, and it was confirmed to have sufficient safety.
【００２３】 また、Ｙｂ169 線源を上述した放射線源容器内に収容した状態で外部に出る放 射線量は、法規上の許容線量２ｍｓ／ｈに対して０．４ｍｓ／ｈ以下であり、十 分な遮蔽状態を示している。Further, the radiation dose emitted to the outside in the state where the Yb 169 radiation source is housed in the above-mentioned radiation source container is 0.4 ms / h or less with respect to the legally permitted dose of 2 ms / h, It shows a sufficient shielding state.
