Abstract
Dosimètre personnel pour impuretés gazeuses. Le dosimètre comprend une poche scellée à chambre de réaction qui contient un milieu collecteur de gaz et au moins un compartiment 6. Chaque compartiment est étanche et contient un réactif différent et peut être mis en communication avec la chambre de réaction 5. Dans la poche est scellé un dispositif de diffusion de gaz 3 formé de fibres creuses, parallèles maintenues ensemble. Le dispositif de diffusion fait communiquer l'atmosphère avec l'intérieur de la chambre de réaction. Application aux dosimètres pour polluants atmosphériques.
