80. Up-to-date dose conversion factors for radon isotopes and their historical overview

Prof. Shinji Tokonami

29/06/2022 09:00

Invited talk

New radon conversion factors (DCF) for radon/thoron progeny have been presented in the ICRP Publication 137 (2017). There used to be a large difference in the DCF between those derived from epidemiological (ICRP 65) and from dosimetric approaches (ICRP 66). This revision results in a higher DCF than before. Hereafter a variety of radon issues may arise. In the present talk, the following...

98. On the use of numerical models to predict/mitigate indoor radon levels in highly contaminated areas

Prof. Lluís Font Guiteras (Universitat Autònoma de Barcelona , Spain)

Invited talk

The publication of the EURATOM directive BSS 2013/59 [1] has increased considerably the interest on radon studies in all EU countries. Certainly each member state has to establish a national action plan addressing long-term risks from radon exposures in dwellings, buildings with public access and workplaces for any source of radon ingress, whether from soil, building materials or water. The...

58. Proposal of an affordable method to estimate indoor thoron concentration close to the walls using active radon monitors

Several continuous radon monitors (CRM) are also sensitive to thoron. This phenomenon, called thoron interference, could lead to overestimate the actual indoor radon concentrations and it is considered an issue for some CRMs, especially for those not able to perform alpha spectrometry of radon daughters. For this reason, radon measurement protocols generally recommend to deploy such CRMs not...

55. Some Applications of Novel Polycarbonate/ACF Radon Detectors for Personal and Environmental Monitoring

ORAL

Polycarbonate track detector (PCTD) have found wide applications in particular when used in radon monitoring cups [1-3]. In order to overcome some deficiencies such as long-term exposures required, recently Tommasino and coworkers [4] introduced a novel Activated Carbon Fabric (ACF)/CR-39 detector in which the ACF adsorbs radon on its active sites and exposes the CR-39; when CR-39 is...
