[en] This document makes a review of this conference day on biological and health effects of non-ionizing radiations. The program comprised three sessions with a total of 17 presentations dealing with: 1 - NMR: biological effects and implications of Directive 2004/40 on electromagnetic fields (S. Lehericy); 2 - impact of RF frequencies from mobile telephone antennas on body homeostasis (A. Pelletier); 3 - expression of stress markers in the brain and blood of rats exposed in-utero to a Wi-Fi signal (I. Lagroye); 4 - people exposure to electromagnetic waves: the challenge of variability and the contribution of statistics to dosimetry (J. Wiart); 5 - status of knowledge about electromagnetic fields hyper-sensitivity (J.P. Marc-Vergnes); 6 - geno-toxicity of UV radiation: respective impact of UVB and UVA (T. Douki); 7 - National day of prevention and screening for skin cancers (F. Guibal); 8 - UV tan devices: status of knowledge about cancer risks (I. Tordjman, and J. Gaillot de Saintignon); 9 - In vitro study of the extremely low frequencies (ELF) effect on genes expression (J.F. Collard); 10 - modulation of brain activity during a tapping task after exposure to a 3000 μT magnetic field at 60 Hz (M. Souques and A. Legros); 11 - calculation of ELF electromagnetic fields in the human body by the finite elements method (R. Scoretti); 12 - French population exposure to the 50 Hz magnetic field (I. Magne); 13 - LF and static fields, new ICNIRP recommendations: what has changed, what remains (B. Vey. Veyret); 14 - risk assessment of low energy lighting systems - DELs and CFLs (J.P. Cesarini); 15 - biological effects to the rat of a chronic exposure to high power microwaves (R. De Seze); 16 - theoretical and experimental electromagnetic compatibility approaches of active medical implants in the 10-50 Hz frequency range: the case of implantable cardiac defibrillators (J. Katrib); 17 - French physicians and electromagnetic fields (M. Souques). (J.S.)
