Apparatus for exposure of polymeric and damp-proof materials to radon

摘要

the pack is tvorenu00e9 expozicnu00ed chamber (1) from a corrosion-resistant material of souciniteli radon diffusion less than 1.10.sup. - 12.n.m.sup.2.n. / with opatrenou just uzavu00edratelnu00fdm lid (2).under the lid (2) is located rovnobeu017ene with detachable structure (3) for the holding of the sample (4). the space above the sample (4) is connected with the space under the samples (4) of the two circuits.the source circuit is tvoren first uzavu00edratelnu00fdm and regulacnu00edm valve (5.1) vyu00fastenu00edm to expozicnu00ed chamber (1) in the lid (2) and linked through the first prutokovu00e9 pump (7).1) and the source (6) of radon with the second uzavu00edratelnu00fdm and regulacnu00edm valve (5.2) zau00fastenu00fdm to expozicnu00ed chamber (1) in the space below the samples (4).meru00edcu00ed circuit in case of manual monitoring tvoren first uzavu00edratelnu00fdm valve (10).1) for the odber sample air for the purpose of radon activity concentration in a separate meru00edcu00edm a machine, where the first dedicated waste valve (10.1) vyu00fasten to expozicnu00ed chamber (1) in the lid (2).in the case of automatic monitoring of radon activity concentration is the first dedicated waste valve (10.1) connected through a continuous radon monitor (8) and through the second prutokovu00e9 pump (7).2) with the second uzavu00edratelnu00fdm valve (10.2) zau00fastenu00fdm to expozicnu00ed chamber (1) in the space below the samples (4).
