The Stockholm Central Railway Station in Sweden was investigated for public radiofrequency (RF) radiation exposure. The exposimeter EME Spy 200 was used to collect the RF exposure data across the railway station. The expo-simeter covers 20 different radiofrequency bands from 88 to 5,850 MHz. In total 1,669 data points were recorded. The median value for(More)
Radiofrequency radiation in the frequency range 30 kHz–300 GHz was evaluated to be Group 2B, i.e. ‘possibly’ carcinogenic to humans, by the International Agency for Research on Cancer (IARC) at WHO in May 2011. Among the evaluated devices were mobile and cordless phones, since they emit radiofrequency electromagnetic fields (RF-EMF). In addition to the(More)
Many schools and educational institutions are using wireless Wi-Fi and Tablet technologies in their education. Recently WHO IARC classified radiofrequency (RF) radiation 'possibly carcinogenic to humans'. Currently guidance levels for electromagnetic fields (including RF) are based on thermal effects while effects have been reported on non-thermal levels.(More)
