摘要
本文分别用二种方法测定了用于操作放射性物质的三种材料(天然橡胶、氯丁和丁基橡胶)制成的乳胶手套薄膜的透气系数P_g、透气量Q_g、透湿系数P_v、透湿量Q_y和对^(210)Po等放射性核素的渗透系数。用真空压力法测得的三种材料四种气体(H_2、CO_2、O_2、N_2)的P_g值为(4.04×10^(-2)—3.66)×10^(-10)cm^2·s^(-1)·mmHg^(-1),Q_g值为(0.0249—2.18)×10^(-8)m^3·m^(-2)·d^(-1)·Pa^(-1);用重量法(透湿杯法)测得的三种材料五种型号手套薄膜的P_v值(0.157—2.23)×10^(-11)g·cm·cm^(-2)·s^(-1)·mmHg^(-1);Q_v值为0.30—20.3g·m^(-2)·d^(-1);用透湿杯法测得的对^(210)Po的渗透系数为1.42×10^(-2)—67.9mL·m^(-2)·d^(-1)。
This paper described determination of permeatingperformances of rubber gloves used in handling radisotope. The gaseouspermeating coefficient Pg and the permeating capacities Q: were measuredby pressure methods;As well as the Pv, Qv for vapour and the Pw, Qwfor water were measured by a weight method.The permeating quantitiesGz and the permeating capcities Qz for radionuclide (such as ^(210) Po ect.)solution were measured by a permeating cup method.Some curvescharacterized the relationship of the permeating parameters were given inthis paper.
