Background: Everyday exposure to radiofrequency electromagnetic fields (RF-EMF) emitted from wireless devices such as mobile phones and base stations, radio and television transmitters is ubiquitous. Some people attribute non-specific physical symptoms (NSPS) such as headache and fatigue to exposure to RF-EMF. Most previous laboratory studies or studies that analyzed populations at a group level did not find evidence of an association between RF-EMF exposure and NSPS. Objectives: We explored the association between exposure to RF-EMF in daily life and the occurrence of NSPS in individual self-declared electro hypersensitive persons using body worn exposimeters and electronic diaries. Methods: We selected seven individuals who attributed their NSPS to RF-EMF exposure. The level of and variability in personal RF-EMF exposure and NSPS were determined during a three-week period. Data were analyzed using timeseries analysis in which exposure as measured and recorded in the diary was correlated with NSPS. Results: We found statistically significant correlations between perceived and actual exposure to wireless internet (WiFi - rate of change and number of peaks above threshold) and base stations for mobile telecommunications (GSM+UMTS downlink, rate of change) and NSPS scores in four of the seven participants. In two persons a higher EMF exposure was associated with higher symptom scores, and in two other persons it was associated with lower scores. Remarkably, we found no significant correlations between NSPS and timeweighted average power density, the most commonly used exposure metric. Conclusions: RF-EMFexposure was associated either positively or negatively with NSP Sinsome but not all of the selected self-declared electro hypersensitive persons. https://doi.org/10.1016/j.envint.2018.08.064

Op 28-29 september gaat de Motocross of Nations (MXON) plaatsvinden op het TT Circuit. Dit evenement is het summum van de motorcross en staat te boek als de Olympische Spelen van deze tak van sport. In tegenstelling tot de reguliere grand prix series nemen tijdens de MXON landenteams het tegen elkaar op. Dankzij een unieke talentvolle lichting met Jeffrey Herlings, Glenn Coldenhoff en Calvin Vlaanderen gaat Nederland in Assen strijden om voor het eerst in de historie dit prestigieuze evenement te winnen. De organisatie van een topevenement als dit kan tegenwoordig echter niet meer zonder een maatschappelijk activatieprogramma. SportDrenthe / Kenniscentrum Events is gevraagd om samen met het consortium bestaande uit de KNMV, Drenthe College, MXGP Academy en LDP Internationaal vorm te geven aan dit programma.
