RADIATION SHIELDING FLEXIBLE CONTAINER BAG, AND RADIATION SHIELDING BAG

PROBLEM TO BE SOLVED: To provide a radiation shielding woven fabric having high strength and elongation and capable of reducing the leakage quantity of radiation of a radioactive substance covered therewith to the outside, a radiation shielding flexible container bag and a radiation shielding cover including the same, and a radiation shielding bag.SOLUTION: The radiation shielding woven fabric is formed by weaving a tape yarn that has a strength of 3.0 cN/dt or greater and is formed by using a raw material for kneading including 20-90 wt.% of thermoplastic synthetic resin and 10-80 wt.% of barium sulfate. The radiation shielding flexible container bag, the radiation shielding cover and the radiation shielding bag are made by using the woven fabric as a raw material. Thus, the strength is high, and the leakage quantity of radiation of a covered radioactive substance to the outside was able to be reduced. 【課題】強伸度が高く、覆った放射性物質の放射線の外部漏洩量を低減可能な放射線遮蔽織物およびこれを用いた放射線遮蔽フレキシブルコンテナバッグおよび放射線遮蔽カバーならびに放射線遮蔽袋を提供する。【解決手段】熱可塑性合成樹脂２０〜９０重量％と、硫酸バリウム１０〜８０重量％との混練用原料を用いて作製された強度が３．０ｃＮ／ｄｔ以上のテープヤーンから放射線遮蔽織物を製織した。また、この織物を原材料とし、放射線遮蔽フレキシブルコンテナバッグ、放射線遮蔽カバーならびに放射線遮蔽袋を作製した。そのため、強度が高く、覆った放射性物質の放射線の外部漏洩量を低減できた。【選択図】図１
