Despite of the rapidly increasing number of short range wireless applications and devices in healthcare environments, very little is know about the radiofrequency (RF) exposure due to such devices.
The most widespread model of social alarm devices was identified from among the most used in telecare monitoring activities. The levels of electromagnetic (EM) field in near field conditions were measured inside an anechoic chamber with a specific absorption rate (SAR) fully automated test system, DASY5PRO. The obtained results were compared with the levels set by international regulations to analyze the exposure to EM fields.
In very close areas to the device, the obtained electric field levels show that local exposure can reach the most restrictive value of 3 V/m that is established in the International Electrotechnical Commission Standard of Electromedical Devices.
