Description

本発明は、医療現場にて患者の患部の検査又は放射線治療等に用いられる放射性物質の保管用として用いる容器又は不要となった放射性廃棄物５を処理するための容器として、鉛等の重金属等にて形成した放射線遮蔽容器１内に前記放射性物質保管用容器２６又は放射性廃棄物５投入用容器２を収容し、前記放射線遮蔽容器１の上部に設けた上方向に開閉可能な蓋４により放射線漏れが無いように密閉する構造の場合又は前記蓋４の一部に放射性廃棄物５投入用孔６を設けて放射性廃棄物５用容器２内に放射性廃棄物５を投入して放射線漏れの無いように収容しかつ投入された放射性廃棄物５からの放射線漏れが無いように放射性廃棄物５投入用孔６を水平方向移動可能な蓋７にて速やかに開閉及び密閉出来る構造として放射線漏れを極力抑えるように形成したもの或いは投入用孔から放射線漏れの無いように投入用孔６の上部を覆いかぶさるように形成すると共に投入用孔６の下部には放射性廃棄物５を案内すると共に放射線遮蔽用の案内部材を形成した放射線遮蔽容器１を用い、前記放射性廃棄物５を放射性廃棄物を処理する作業者が直接前記放射線遮蔽容器１内に投入する事が出来るようにするとともに放射性物質又は放射性廃棄物５を収納する容器２を安全な貯蔵場所或いは廃棄処理場に手軽に移動させることが出来る移動式放射線遮蔽容器１に関するものである。
放射線治療の進歩に伴って放射性物質５を患部の検査用又は放射線照射等の医療に取り入れられるに従って従来の放射線遮蔽対策では心許ないことから近年新しい放射線遮蔽対策が考えられて来ているが一般に放射線被爆に対する危険意識が薄く被爆低減対策は余りとられていないのが現状である。また放射性物質５の放射線遮蔽対策として用いられる鉛等の重金属は重量が有るため大型の放射性廃棄用容器を取り扱うための吊り上げ移送設備等の設置は、高額の設備費用を伴うことから病院等の医療現場では敬遠されがちである。従って鉛等で形成した小型の重金属製ブロックを用いて放射性廃棄物５投入用容器の周囲に積み上げて形成した状態で放射性物質５を収納した前記容器を一定期間放置するか又は小量の放射性物質５を小型の遮蔽容器に少しずつ収容して運搬処理する程度のものしか考えられていない。しかしこれらの簡易遮蔽構造は上部が開放されているため放射線に被爆する恐れがあり、また地震などの場合忽ち崩れて前記容器が剥き出しになる場合或いは前記容器が地震で倒れた場合近辺に放射性廃棄物が散乱し放射線で汚染される危険を伴う欠点を有するものである。
また第１０図に示すように鉛板或いはステンレス板或いは鋼板等の板状部材を用いて多数の仕切り板を設け、放射性廃棄物５の大小又は種類に応じて成形した複数の小型容器を収容し、それぞれの小型容器内に放射性廃棄物５の大小又は種類に応じて放射性廃棄物５を仕分けして投入し保存している。但し放射性廃棄物５は指定期間内に廃棄処理を行わなければならない規定があるため、それぞれの容器内の放射性廃棄物５は期限内に廃棄処理しなければならない必要がある。
そこで本発明は、放射性物質の保管用として用いる場合又は前記小型容器内の放射性廃棄物５を処理するために、鉛等の重金属を用いて移動式放射線遮蔽容器１を形成したものであるが、前記移動式放射線遮蔽容器１は重量物であるにもかかわらず人力で移動が可能であり、しかも放射性物質又は放射性廃棄物５の取扱い作業者の放射線被爆を防ぎしかも手軽にかつ速やかに放射性物質又は放射性廃棄物５を前記容器１内に収納し、直ちに安全な貯蔵場所或いは廃棄場所若しくは放射性物質の使用箇所等に移動して処理することができる優れた移動式放射線遮蔽容器１を提供するものである。The present invention can be used as a container for storing radioactive materials used for examination of a diseased part of a patient or radiotherapy at a medical site, or as a container for processing radioactive waste 5 that is no longer needed. The radioactive substance storage container 26 or the radioactive waste 5 input container 2 is accommodated in the radiation shielding container 1 formed in Step 1, and radiation is applied by an upwardly openable lid 4 provided on the radiation shielding container 1. In the case of a structure that is hermetically sealed so that there is no leakage, the radioactive waste 5 charging hole 6 is provided in a part of the lid 4 and the radioactive waste 5 is introduced into the radioactive waste 5 container 2 so that there is no radiation leakage. In order to prevent radiation leakage from the radioactive waste 5 that has been accommodated and introduced in this way, the radioactive waste 5 injection hole 6 can be quickly opened and closed and sealed with a lid 7 that can be moved in the horizontal direction. Suppression Or formed so as to cover the upper part of the input hole 6 so as not to leak radiation from the input hole, and guides the radioactive waste 5 to the lower part of the input hole 6 and for shielding radiation. Using the radiation shielding container 1 in which the guide member is formed, the radioactive waste 5 can be directly put into the radiation shielding container 1 by an operator who processes the radioactive waste 5 and the radioactive material or radioactive waste is disposed. The present invention relates to a mobile radiation shielding container 1 capable of easily moving a container 2 for storing an object 5 to a safe storage place or a disposal processing place.
With the progress of radiation therapy, new radiation shielding measures have been considered in recent years because radioactive substances 5 are incorporated in medical treatments such as examination of affected areas or radiation irradiation. At present, there is little awareness of dangers, and there are not many measures to reduce exposure. In addition, heavy metals such as lead used as a radiation shielding measure for radioactive material 5 are heavy, so the installation of lifting and transporting equipment for handling large radioactive waste containers is expensive and requires medical equipment such as hospitals. They tend to be shy away from the scene. Therefore, the container containing the radioactive material 5 is left standing for a certain period in a state where it is formed by stacking around the container for charging the radioactive waste 5 using a small heavy metal block formed of lead or the like, or a small amount of radioactive material Only the thing of the grade which accommodates 5 in a small shielding container little by little and conveys it is considered. However, these simple shielding structures are open at the top, so there is a risk of exposure to radiation, and in the event of an earthquake or the like, if the container collapses and the container is exposed, or if the container collapses due to an earthquake, the radioactive waste will be It has the disadvantage that there is a risk that the object will be scattered and contaminated with radiation.
Further, as shown in FIG. 10, a number of partition plates are provided using plate members such as lead plates, stainless steel plates, and steel plates, and a plurality of small containers formed according to the size or type of radioactive waste 5 are accommodated. In each small container, the radioactive waste 5 is sorted and input according to the size or type of the radioactive waste 5 and stored. However, since there is a provision that the radioactive waste 5 must be disposed of within a designated period, the radioactive waste 5 in each container must be disposed of within the time limit.
Therefore, in the present invention, the mobile radiation shielding container 1 is formed using a heavy metal such as lead in order to use it for storage of radioactive substances or to treat the radioactive waste 5 in the small container. Although the mobile radiation shielding container 1 is a heavy object, it can be moved by human power, and the radioactive material or radioactive waste 5 is prevented from being exposed to radiation by a worker who handles the radioactive material or the radioactive waste 5 easily and quickly. Provided is an excellent mobile radiation shielding container 1 in which radioactive waste 5 is stored in the container 1 and can be immediately moved to a safe storage place or disposal place or a place where radioactive material is used. is there.

従来病院等の医療現場にて患部の検査又は放射線照射治療に使用される放射性物質は簡易包装容器を用いて処理しているため搬送者又は治療担当者の放射線被爆は免れず、又使用後不要となった放射性廃棄物５の処理は、鉛等の重金属を用いて形成した重量のある放射線遮蔽容器を設置して対応する場合、現存の病院内では重量物の放射線遮蔽容器の移送及び前記放射線遮蔽容器内に放射性廃棄物を投入する際の蓋の開閉に対応出来る吊り上げ装置又は移送設備を新たに設置しなければならないが、これらの設備は高額の設備費用を伴うことから病院等の医療現場では敬遠されがちである。そのため多くの病院は鉛等の重金属で形成した小型ブロック等を用いて組み合わせ三面体或いは四面体等の簡易放射線遮蔽構造体を構成してその内部に小型容器を複数個設置し、前記小型容器内に放射性廃棄物５の不燃物、可燃物、注射針等の仕分けしたものを一時保管し、保存指定期間内に随時持ち運び可能な放射線遮蔽容器に移し変えるか又はそのまま少量の放射性廃棄物５を移送して廃棄処理しているのが現状である。
従って前記簡易包装容器又は簡易放射線遮蔽構造体では放射性物質又は放射性廃棄物５の移送処理を少量づつしか対応できず放射性廃棄物５の処理に多大の移送手間と処理時間を要する欠点を要し、またそれらの放射性物質又は放射性廃棄物５の貯蔵時及び移送又は移し替え作業の際に放射性物質又は放射性廃棄物５から放射されている放射線の完全遮蔽は困難であり移送処理又は移し替え作業時において放射性物質又は放射性廃棄物５を取扱う作業者が放射線に被爆する恐れが極めて大きい。従って放射性物質の取扱時又は放射性廃棄物５の移し替え作業時に作業者が放射線に被爆されないよう細心の注意を払って作業を行わなければならない等の煩わしさを有し、また震度５以上の地震が発生した場合、上記のようなブロック積み上げ構造の簡易放射線遮蔽構造では地震発生と同時に忽ちブロックが崩れて放射性廃棄物５を収納した容器が剥き出しとなる場合或いは容器が崩れたブロックに押し倒された場合には容器内の放射性廃棄物５がその近辺に散乱し、貯蔵場所が放射線で汚染される危険性が大である等多くの欠点を有するものである。Conventionally, radioactive substances used for examination of affected areas or radiation treatment at hospitals and other medical sites are processed using simple packaging containers, so the radiation exposure of carriers or treatment personnel is not exempted and is not required after use. When the radioactive waste 5 thus processed is handled by installing a heavy radiation shielding container formed using heavy metals such as lead, the transfer of the heavy radiation shielding container and the radiation are performed in an existing hospital. It is necessary to newly install lifting equipment or transfer equipment that can cope with opening and closing of the lid when radioactive waste is put into the shielding container, but these equipment involve expensive equipment costs, so medical facilities such as hospitals etc. Then, it tends to be shunned. For this reason, many hospitals use a small block made of heavy metal such as lead to form a simple radiation shielding structure such as a combination trihedron or tetrahedron and install a plurality of small containers inside the small container. In addition, temporarily store the non-combustible materials, combustible materials, injection needles, etc. of the radioactive waste 5 and transfer it to a radiation shielding container that can be carried at any time within the designated storage period or transfer a small amount of the radioactive waste 5 as it is. The current situation is that they are disposed of.
Therefore, the simple packaging container or the simple radiation shielding structure can deal with the transfer processing of the radioactive substance or the radioactive waste 5 only in small amounts, and the processing of the radioactive waste 5 requires a large amount of labor and time. It is difficult to completely shield radiation emitted from radioactive materials or radioactive waste 5 during storage or transfer or transfer of those radioactive materials or radioactive waste 5 and radioactive during transfer processing or transfer operations. There is a great risk that an operator handling the substance or radioactive waste 5 will be exposed to radiation. Therefore, when handling radioactive materials or transferring radioactive waste 5, there is an annoyance such that workers must be careful to avoid being exposed to radiation, and earthquakes with a seismic intensity of 5 or more. In the case of a simple radiation shielding structure with a block stacking structure as described above, when the earthquake occurred, the block collapsed and the container containing the radioactive waste 5 was exposed, or the container was pushed down by the collapsed block In some cases, the radioactive waste 5 in the container is scattered in the vicinity thereof, and there are many disadvantages such as a large risk that the storage place is contaminated with radiation.

本発明は上述した従来の欠点を改善し、鉛等の重金属にて形成した重量の有る放射線遮蔽容器１にも拘らず前記容器１内に挿入した放射性物質の保管又は放射性廃棄物５の投入操作が極めて容易でかつ速やかに行えるので放射線漏れが少なくてすみ放射線被爆の恐れが極めて少ない利点を有し、更に放射性物質又は放射性廃棄物５を収容した放射線遮蔽容器１の移動が手軽でかつ速やかに所要箇所に移動することが出来る特徴を有する優れた移動式放射線遮蔽容器１を提供するものである。  The present invention improves the above-mentioned conventional drawbacks and stores radioactive materials inserted into the containers 1 or throws in radioactive wastes 5 in spite of the heavy radiation shielding containers 1 formed of heavy metals such as lead. Is very easy and quick, so there is less radiation leakage and the risk of exposure to radiation is very low. Furthermore, the radiation shielding container 1 containing radioactive material or radioactive waste 5 is easily and quickly moved. The present invention provides an excellent mobile radiation shielding container 1 having a feature that it can move to a required location.

本発明の移動式放射線遮蔽容器１について図１から図６に示す第１実施例に基づき具体的に説明すると、本発明の第１実施例は図１から図３に示され、一列として市販の円形ドラム或いは日本アイソト−プ協会仕様の円筒状放射性廃棄物５投入用容器２を本発明の移動式放射線遮蔽容器１の内部に収納して放射性廃棄物５から発生する放射線を遮蔽して外部に漏れないようにするために前記移動式放射線遮蔽容器１は鉛等の重金属を用いて円形又は角形の放射線遮蔽用容器１を形成したものである。なお前記容器１に用いている鉛等の重金属は強度的に弱いので鋼板等の材料でその周囲を補強して放射線遮蔽容器１を構成している。
さらに前記移動式放射線遮蔽容器１は前述のように鉛等の重金属で形成しているために総重量が５００乃至６００キログラム程度にもなるので容器本体の持ち運びが大変なことから前記容器１の下部にキャスタ−１０を３ヵ所以上取り付け、さらに側面の任意の箇所に移送用のハンドル２２を取り付けて前記容器１の移動が楽なように形成している。但し重量がある移動式放射線遮蔽容器１なので傾斜面に設置した場合放射線遮蔽容器１自体が勝手に移動してしまう恐れがあるので滑り止め用アジャスタパット２３をキャスタ−１０の近辺に設けて前記容器１が勝手に移動するのを防止するように形成している。
前記放射線遮蔽容器１の上部３には一端を軸２１で支持され上下方向に開閉される蓋４を設け、前記蓋４を上方に開放することにより前記放射性廃棄物用容器２を上部から前記放射線遮蔽容器１内に収納出来るように形成している。
さらに前記蓋４には前記放射線遮蔽容器１内に収納された放射性廃棄物用容器２内に放射性廃棄物５を投入するために半円形又は円形又は角形に形成した投入用孔６を設けている。なお前記投入用孔６を開放したままでは前記放射性廃棄物用容器２内に投入された放射性廃棄物５から発生する放射線が前記孔６から漏れるため前記投入用孔６の上面に鉛等の重金属製蓋７を水平方向に移動させて開閉するように形成している。しかし前記蓋７は鉛等の重量物で形成しているため動きづらいので前記蓋７の両側に移動用案内装置を設けている。前記案内装置は前記蓋４の上面に敷設された２本のレ−ル１２と前記蓋７の両端に取り付けた跨ぎ部材１３とから構成されている。前記レ−ル１２の中心線上には前記跨ぎ部材１３との接触滑動を良くするためにボ−ル１８を複数カ所埋め込んでいる。なお前記ボ−ルに変えて跨ぎ部材にロ−ル１９を取り付けレ−ル１２上を滑動させるように形成しても良い。
前記移動式放射線遮蔽容器１の蓋４は前記容器１の側壁面と同様に放射性廃棄物５から発生する放射線を遮蔽する目的で鉛等の重金属で形成しているため蓋４自体も１００キログラム程度の重量があり放射性廃棄物５投入用容器２の出し入れの際の蓋４の上下開閉操作が極めて困難なことから蓋４の両側にガススプリング２０を取り付け前記蓋４に常時上向きの圧力を加えて前記蓋４の上下開閉操作を補助するように設けている。
また移動式放射線遮蔽容器１内に収納した放射性廃棄物５投入用容器２を上部から出し入れする際に上部に障害物があって出し入れ不能の場合もあり得るので前記移動式放射線遮蔽容器１の側壁面に片開き扉１１或いは両開きの扉１１設けるか或いは図５及び図６に示すような回転扉２３を設けて側面から放射性廃棄物用容器２を小型のフオ−クリフト等を用いて側面から出し入れ出来るように構成してもよい。
第１実施例の移動式放射線遮蔽容器１は上記のように蓋４に水平方向に移動可能な蓋７を設けて投入用孔６を塞ぐように形成しているが、図４に示すような前記投入用孔６の第２実施例では前記蓋４に設けた投入用孔６の上面に前記投入用孔６を覆うように覆い部材１８を設け、さらに前記投入用孔６の下部には放射性廃棄物５を前記容器２内に投入する際の投入用案内部材１７を設けている。この覆い部材１８と前記案内部材１７は鉛等の重金属で形成して容器２内に投入された放射性廃棄物５から発生する放射線が投入用孔６から外部に漏洩しないように形成しているものである。なお前記投入用孔６の第２実施例では投入用孔６の内外で案内部材１７と覆い部材１８をくの字に形成してあり、これは放射線が外部に漏れないようにするとともに放射性廃棄物５を安全に放射性廃棄物容器２内に投入出来るように形成したものである。The mobile radiation shielding container 1 of the present invention will be described in detail with reference to the first embodiment shown in FIGS. 1 to 6. The first embodiment of the present invention is shown in FIGS. A circular drum or cylindrical radioactive waste 5 container 2 specified by the Japan Isotope Association is housed inside the mobile radiation shielding container 1 of the present invention to shield the radiation generated from the radioactive waste 5 and to the outside. In order to prevent leakage, the mobile radiation shielding container 1 is formed by using a heavy metal such as lead to form a circular or square radiation shielding container 1. Since the heavy metal such as lead used for the container 1 is weak in strength, the radiation shielding container 1 is configured by reinforcing the periphery thereof with a material such as a steel plate.
Furthermore, since the mobile radiation shielding container 1 is made of heavy metal such as lead as described above, the total weight is about 500 to 600 kilograms, so it is difficult to carry the container body. The caster 10 is attached to three or more locations, and a transfer handle 22 is attached to any location on the side surface so that the container 1 can be moved easily. However, since the radiation shielding container 1 is heavy, there is a risk that the radiation shielding container 1 itself may move without permission when installed on an inclined surface. Therefore, an anti-slip adjuster pad 23 is provided in the vicinity of the caster 10 to provide the container. It is formed to prevent 1 from moving without permission.
The upper portion 3 of the radiation shielding container 1 is provided with a lid 4 supported at one end by a shaft 21 and opened and closed in the vertical direction. By opening the lid 4 upward, the radioactive waste container 2 is moved from the upper portion to the radiation. It is formed so that it can be stored in the shielding container 1.
Further, the lid 4 is provided with a charging hole 6 formed in a semicircular shape, a circular shape, or a rectangular shape in order to put the radioactive waste 5 into the radioactive waste container 2 accommodated in the radiation shielding container 1. . If the injection hole 6 is left open, radiation generated from the radioactive waste 5 injected into the radioactive waste container 2 leaks from the hole 6, so that a heavy metal such as lead is formed on the upper surface of the injection hole 6. The lid 7 is formed so as to open and close by moving in the horizontal direction. However, since the lid 7 is made of a heavy material such as lead, it is difficult to move. Therefore, a guide device for movement is provided on both sides of the lid 7. The guide device is composed of two rails 12 laid on the upper surface of the lid 4 and straddling members 13 attached to both ends of the lid 7. A plurality of balls 18 are embedded on the center line of the rail 12 in order to improve the sliding contact with the straddling member 13. Instead of the ball, a roll 19 may be attached to the straddling member so as to slide on the rail 12.
The lid 4 of the mobile radiation shielding container 1 is made of heavy metal such as lead for the purpose of shielding the radiation generated from the radioactive waste 5 in the same manner as the side wall surface of the container 1. Therefore, the lid 4 itself is about 100 kilograms. Therefore, it is extremely difficult to open and close the lid 4 when the container 2 for loading the radioactive waste 5 is put in and out. Therefore, gas springs 20 are attached to both sides of the lid 4 so that upward pressure is always applied to the lid 4. The lid 4 is provided so as to assist the opening and closing operation.
In addition, when the radioactive waste 5 input container 2 stored in the mobile radiation shielding container 1 is taken in and out from the upper part, there may be an obstacle at the upper part, so that it cannot be taken in and out. A single door 11 or double door 11 is provided on the wall surface, or a rotary door 23 as shown in FIGS. 5 and 6 is provided, and the radioactive waste container 2 is taken in and out from the side using a small forklift or the like. You may comprise so that it can.
The movable radiation shielding container 1 of the first embodiment is formed so as to close the closing hole 6 by providing the lid 4 with the lid 7 that is movable in the horizontal direction as described above, but as shown in FIG. In the second embodiment of the charging hole 6, a cover member 18 is provided on the upper surface of the charging hole 6 provided in the lid 4 so as to cover the charging hole 6, and the lower part of the charging hole 6 is radioactive. An introduction guide member 17 is provided when the waste 5 is introduced into the container 2. The covering member 18 and the guide member 17 are formed of heavy metal such as lead so that the radiation generated from the radioactive waste 5 thrown into the container 2 is not leaked to the outside from the throwing hole 6. It is. In the second embodiment of the injection hole 6, the guide member 17 and the cover member 18 are formed in a U shape inside and outside the injection hole 6, which prevents radiation from leaking to the outside and radioactive waste. The product 5 is formed so that it can be safely put into the radioactive waste container 2.

第２実施例の移動式放射線遮蔽容器１は、図７から図９に示されているとおり、おもに医療現場にて用いられる放射性物質の保管及び処置室又は病室にで使用の際に手元に置いて患者の患部の処置が可能な放射線遮蔽容器１として用いられるものであり、第１実施例に示される大型の放射線遮蔽容器１に比べて全体的に小型に形成されたものである。
前記放射線遮蔽容器１は、鉛等の重金属を用いて円形又は角型の容器１が形成されている。第１実施例と同様に鉛等の重金属は強度的に弱いのでその周囲を鋼板で補強されている。上面には一端が支持されて上下に開閉可能な蓋４が取付けられている。前記遮蔽容器１の内部には鉛等の重金属を内張りした鋼製バケツ等の容器２６が収納されていて、その内部には放射線検査又は放射線治療に用いられるおもに強力な放射線を発する放射性物質が保管される。前記蓋４の両側面には第１実施例と同様に蓋４を支持して開閉操作がが楽に行えるようにガススプリング２０を設けてあり、前記容器１内の放射性物質５の出し入れを迅速に行えるように形成している。
また前記遮蔽容器１の下部を手押し車２７の上面に固定し、前記遮蔽容器１をいつでも所望の位置例えば医療処置室或いは病室等に移動して患者の処置が出来るように移動式放射線遮蔽容器１を形成したものである。As shown in FIGS. 7 to 9, the mobile radiation shielding container 1 of the second embodiment is mainly stored at the time of storage of radioactive materials used in a medical field and use in a treatment room or a hospital room. Thus, it is used as a radiation shielding container 1 capable of treating an affected area of a patient, and is formed to be small overall as compared with the large radiation shielding container 1 shown in the first embodiment.
As for the said radiation shielding container 1, the circular or square container 1 is formed using heavy metals, such as lead. Similar to the first embodiment, heavy metals such as lead are weak in strength, and hence the periphery thereof is reinforced with a steel plate. A lid 4 that is supported at one end and can be opened and closed vertically is attached to the upper surface. A container 26 such as a steel bucket lined with a heavy metal such as lead is accommodated in the shielding container 1, and a radioactive substance that mainly emits strong radiation used for radiation inspection or radiation treatment is stored in the container. Is done. As in the first embodiment, gas springs 20 are provided on both sides of the lid 4 so that the lid 4 can be supported and opened / closed easily, and the radioactive material 5 in the container 1 can be taken in and out quickly. It is formed so that it can be done.
Further, the lower part of the shielding container 1 is fixed to the upper surface of the handcart 27, and the movable radiation shielding container 1 is provided so that the shielding container 1 can be moved to a desired position such as a medical treatment room or a hospital room at any time to treat a patient. Is formed.

以上述べたように本発明になる鉛等の重金属製移動式放射線遮蔽容器１は、前記移動式放射線遮蔽容器１の上面に蓋４を設け、更に放射性廃棄物５投入用孔６を設けてその上部には放射線漏れを防止するための水平方向開閉自在の蓋７又は覆い部材１８を設け、また前記投入用孔６の下部には放射性廃棄物５投入用の案内部材１７を設けて放射性廃棄物５を前記放射線遮蔽容器１内に収納した放射性廃棄物投入用容器２内に投入するように形成したもの或いは小型の移動式放射線遮蔽容器１を形成して主に放射性物質の保管用に用いるために形成し、さらに放射性物質又は放射性廃棄物５を処理する作業者が放射性物質又は放射性廃棄物５から発生する放射線に被爆されないように放射線を遮蔽しつつ安全に保管又は投入出来るように形成するとともに前記放射線遮蔽容器１の下部にはキャスタ−１０を設けて前記放射線遮蔽容器１を移動自在に形成し、前記移動式放射線遮蔽容器１内に収納された放射性物質の保管及び出入れ操作の際又は放射性廃棄物投入用容器２内に放射性廃棄物５の投入操作を行う際に、前記放射性物質又は放射性廃棄物５から放射される放射線に作業者が被爆されないように移動式放射線遮蔽容器１を形成しているので、重量のある移動式放射線遮蔽容器１にもかかわらず放射性廃棄物５が発生する医療現場の近くに設けた放射性物質の保管場所又は放射性廃棄物５の貯蔵場所に前記移動式放射線遮蔽容器１を設置し、直接作業者が前記放射性物質の保管及び出入れ操作又は前記放射性廃棄物５を前記移動式放射線遮蔽容器１内に投入する事が可能であり、また医療現場近くに放射性廃棄物５の貯蔵場所を設置出来ない場合においても別の場所に設けられた貯蔵場所に貯蔵された放射性廃棄物５の近辺に移動式放射線遮蔽容器１を移動して近づけ投入作業を行うことが出来るので放射性物質又は放射性廃棄物５取り扱い作業者の飛躍的な作業性向上が得られ、更に前記移動式放射線遮蔽容器１内に放射性物質の保管及び出入れ操作の際又は放射性廃棄物５の投入操作の際に放射性廃棄物５を前記移動式放射線遮蔽容器１内に速やかにかつ安全に保管又は投入する事が出来るので放射性物質の保管及び放射性廃棄物５の投入作業にたづさわる作業者を放射線から保護し、更に作業従事者の放射線被爆量が極めて少なくて済むとともに前記移動式放射線遮蔽容器１内への放射性廃棄物５の投入が終了すると直ちに安全な貯蔵場所或いは廃棄場所に移動することが出来る等多くの優れた効果を有する移動式放射線遮蔽容器１である。  As described above, the mobile radiation shielding container 1 made of heavy metal such as lead according to the present invention is provided with the lid 4 on the upper surface of the mobile radiation shielding container 1 and further provided with the holes 6 for introducing the radioactive waste 5. A lid 7 or a cover member 18 that can be opened and closed in the horizontal direction for preventing radiation leakage is provided in the upper part, and a guide member 17 for injecting radioactive waste 5 is provided in the lower part of the introduction hole 6 to provide radioactive waste.
