Deploying reconfigurable intelligent surfaces (RISs) offers the potential to achieve promising quality in millimeter wave (mmWave) communication. However, it also triggers the health concerns associated with electric and magnetic field (EMF) exposure due to base station (BS) transmission and RIS reflection.

This paper provides a stochastic-geometry framework to evaluate the EMF exposure in RIS-assisted mmWave cellular networks. The proposed framework provides insights to establish technical guidelines for ensuring EMF exposure within safe limits. For example, by considering the compliance distance (CD) set for BSs, we explore the necessity of designing a similar CD for RISs.
