Abstract

De acuerdo con la presente invención, se proporciona un dispositivo de difusión de gas para limitar la circulación de un contaminante gaseoso, que incluye: una pluralidad de fibras huecas paralelas, encapsuladas, siendo dichas fibras sustancialmente no higroscópicas e inertes a dichos contaminantes gaseosos y teniendo un diámetro interno de 15-1.000 micrones; y un material encapsulado que llena los espacios longitudinales entre dichas fibras, estando por lo menos uno de los elementos constituidos por dichas fibras y dicho material encapsulado, impermeable a dicho contaminante gaseoso. De acuerdo con otro aspecto de la invención se proporciona un dosímetro personal para medir la concentración media de un contaminante gaseoso durante un periodo de tiempo dado, que incluye; un receptáculo en forma de bolsa herméticamente cerrado, hecho de material polímero plegable, teniendo dicho receptáculo una cámara de reacción adaptada para contener un medio de captación de gas, y por lo menos un compartimiento aislado herméticamente y adaptado para contener un agente reactivo de prueba, pudiendo romperse individualmente los cierres herméticos de cada compartimiento, de tal manera que los agentes reactivos puedan ser introducidos por separado en la cámara de reacción; y un dispositivo de difusión de gas que consiste en un conjunto de fibras huecas paralelas, encapsuladas, estando dispuesto el dispositivo de difusión de manera hermética en el receptáculo y orientado de modo que un extremo de las fibras comunique con la atmósfera, mientras que la otra extremidad comunica con el interior de la cámara de reacción.
