Description
1.防水層と水系溶剤に溶解性の染料を含有する中間染色層とその上の非染色層を備えていることを特徴とするディスポーザブルシート。
2.中間染色層及び非染色層が、水系溶剤吸収性材料からなる前記1に記載のディスポーザブルシート。
3.水系溶剤吸収性材料が紙、織布または不織布である前記2に記載のディスポーザブルシート。
4.防水層が防水性のプラスチックシートからなる前記1に記載のディスポーザブルシート。
5.プラスチックシートがポリオレフィンからなる前記4に記載のディスポーザブルシート。
6.有害物質含有水性溶液による汚染が検知できるシートである前記1乃至5のいずれかに記載のディスポーザブルシート。
7.有害物質が、放射性元素を含有する物質である前記6に記載のディスポーザブルシート。
本発明の汚染検知ディスポーザブルシートの1例の平面図を図1(A)に、その側断面図を図1(B)に示す。
すなわち、例えば、無色の紙シートと染料含有紙シートを重ね、染料含有シート面を接着剤を塗布したポリシートの上に重ねて加圧エンボス加工することにより容易に製造することができる。
本発明の汚染検知ディスポーザブルシートは、下記のようにして使用される。
床または作業台などの上に汚染検知ディスポーザブルシートを敷く。また、ディスポーザブルシートからなる検査衣、実験衣を被験者、検査技師あるいは研究者が身に付けて、有害物質含有水性溶液を取り扱う。検査試薬がディスポーザブルシートに付着した場合は吸収され、汚染部位で表面が染色され容易に確認ができる。汚染から時間が経過し溶媒が蒸発しても汚染部位が染色されているので容易に確認できる。汚染されたディスポーザブルシートは所定の手順で廃棄処理ことにより危険物である検査薬による汚染が防止される。
2 吸水性材料からなる表面非染色層
3 吸水性材料からなる水溶性染料含有中間染色層
4 防水性材料からなる防水層
Claims (3)
- 防水層と水系溶剤に溶解性の染料を含有する中間染色層とその上の非染色層を備え、前記中間染色層及び非染色層が紙、織布または不織布からなり、前記防水層がポリオレフィンからなる、有害物質含有水系溶液による汚染が検知できることを特徴とするディスポーザブルシート。
- 有害物質が、放射性元素を含有する物質である請求項1に記載のディスポーザブルシート。
- 請求項1または2に記載のディスポーザブルシートからなる検査衣または実験衣。
