Effects of high-frequency electromagnetic fields emitted from card readers of access control systems on electronic pocket dosimeters.

چکیده
High-frequency electromagnetic fields in the 120 kHz band emitted from card readers for access control systems caused abnormally high doses on electronic pocket dosimeters (EPDs). All EPDs recovered their normal performance by resetting after the exposure ceased. The electric and magnetic immunity levels of the EPDs were estimated by using the distances needed to prevent electromagnetic interference.
