Intake of radionuclides: in vivo internal monitoring of exotic radioisotopes

Siria Medici, Institut de radiphysique (IRA), CHUV Lausanne

Abstract: In this talk I will describe our approach to develop a new in vivo internal monitoring programme for the CERN workers that is compatible with the Swiss regulation. The risk of internal contamination at CERN increased following the commissioning of the CERN-MEDICIS facility, which produces short-lived and exotic radionuclides for medical research that are not considered in the Swiss Personal Dosimetry Ordinance. This talk will present the different topics covered during the PhD project : the development of a computer program allowing to solve the biokinetic models of the considered radionuclides, the description of a pragmatic procedure to assess the suitability of conventional radiation protection instruments to perform in vivo screening measurements (Triagemessungen) and the ability of two portable spectrometers to quantify intakes in different phantoms.

Using minerals as dosimeters

Georgina King & Lily Bossin, Institute of Earth Surface Dynamics, University of Lausanne

Natural minerals like quartz or fluorite behave as natural radiation dosimeters. The radiation dose received by these minerals can be quantified using luminescence methods, allowing questions ranging from retrospective accident dosimetry to the timing of landscape evolution to be addressed. In this seminar, the principles of luminescence dosimetry will be outlined, followed by a discussion of its applications in both personal dosimetry and the Earth sciences.
