Abstract

Overview

Short range wireless RFID technology is widely used in healthcare environments, where it must coexist with other electromagnetic sources and patient implants. This study focuses on the exposure conditions near EM fields created by RFID systems.

Findings

  • Discussion on near EM field conditions by RFID reader based on results from anechoic chamber measurements and numerical simulations.
  • Consideration of human EM exposure evaluation principles and limitations according to international guidelines.
  • Significant increase in near field exposure when a person is nearby the RFID reader, with implications for those within 50 cm of the device.

Conclusion

Critical analysis of EM exposure near RFID readers, especially considering the impact on healthcare personnel and patients with medical implants. It stresses the importance of adherence to safe exposure levels to mitigate health risks.
