  1. Study of a passive detector for retrospective radon measurements.

    Article, Communication - En anglais

    International Conference on Nuclear Tracks in Solids. Dubna (RUS), 1994/08/24.

    It is a well known fact that radon is the most important factor in the natural radiation background.

    For complete risk estimation we need information about the the past radon exposure.

    As suggested by C. Samuelsson et at. in 1988, the activity of the implanted radon daughter 210Po can be used to reconstruct the radon activity over the past decades.

    For large scale surveys in dwellings a passive polycarbonate detector has been investigated.

    A technique of heating these detectors to temperatures up to 110°C has been tested to reduce the number of background tracks, present in the detector after long time storage.
