一种用于放射性碘测量的活性炭取样滤膜
摘要：
本发明涉及一种用于气流中放射性碘取样测量的活性炭取样滤膜，其结构包括顶层空气滤膜和底层空气滤膜，在两层空气滤膜之间设有使活性炭均匀分布的支撑纤维，在支撑纤维上设置活性炭层，顶层空气滤膜和底层空气滤膜的边缘无活性炭的环状部分通过胶粘剂粘接。本发明的放射性碘活性炭取样滤膜能够满足用于放射性碘取样装置要求的滤膜阻力、粒子穿透率、放射性碘吸附动态容量、放射性碘穿透率等各项要求，其成本低，制作和使用方便，对放射性碘的取样效率高。
摘要（英）：

The present invention relates to an active carbon sampling filtration membrane for sampling measurement of radioactive iodine in gas flow. The structure comprises a top layer air filtration membrane and a bottom layer air filtration membrane, wherein support fibers for making active carbon be uniformly distributed are arranged between the two air filtration membrane layers, and are provided with an active carbon layer, and the active-carbon-free annular part on the edge of the top layer air filtration membrane and the bottom layer air filtration membrane is adhered through an adhesive. According to the present invention, the active carbon sampling filtration membrane can meet various performance requirements of filtration membrane resistance, particle penetration, dynamic radioactive iodine adsorption capacity, radioactive iodine penetration and the like of the radioactive iodine sampling equipment, and further has characteristics of low cost, easy production, easy use, and high radioactive iodine sampling efficiency.
