Radiological protection is a matter of concern for members of the public and thus national authorities are more likely to trust the quality of radioactivity data provided by accredited laboratories using common standards. Normative approach based on

At the Paul Scherrer Institute's Calibration Laboratory, neutron reference fields are provided for the calibration of ambient and personal dose equivalent (rate) metres and passive dosemeters. To ensure traceability to the standards of the Physikalis

Radon is considered to be the main source of human exposure to natural radiation. As stated by the World Health Organization, the exposure due to the inhalation of indoor radon is much greater than the one via the ingestion of water as radon degasses

Locally produced vitamin D metabolites are of high importance for growth regulation in various tissues. Using real-time PCR, we have characterized expression of key components of the vitamin D system vitamin D receptor (VDR), vitamin D-25-hydroxylase

An exposure methodology was developed for the determination of the absorption rate of unattached radon progeny deposited in the human respiratory tract to blood. Twenty-one volunteers were exposed in a radon chamber during well-controlled aerosol and

Seven nose breathing and seven mouth breathing volunteers were exposed to atmospheres enriched with unattached radon progeny ( 218 Po, 214 Pb and 214 Bi). The activity of these radionuclides deposited in the respiratory tract was measured in vivo aft

Starting in 1996, nonlinear approximation algorithms used for the determination of size distributions of ''unattached'' radon progeny from measurements made with diffusional size classification instruments were compared. Seven participants (one Ameri

The size distribution of the unattached fraction of the short-lived radon progeny is reported in the literature to have a bimodal structure. Due to the weak size resolution of diffusional size classification, a wide variety of bimodal size distributi

The radon chamber model developed at the Paul Scherrer Institut (PSI) is covering differences in size between the different short-lived radon daughters by taking into account nuclide specific deposition and attachment rates. The resulting set of diff
