Jan 1, 2025
This exposure-assessment study uses FDTD simulations to evaluate auto-induced downlink RF-EMF exposure at 3.5 GHz when downlink energy is focused toward user equipment near the head. Exposure varied substantially by device position (ear, eyes, nose) and by the precoding technique used. The authors report that the…

This single-arm 12-week pilot/feasibility study enrolled 25 relatively healthy adults to evaluate an in-home resonance-based EMF protection device (BluShield). The abstract reports high compliance and no adverse events, with modest improvements in self-reported health, several cognitive questionnaire domains, and…

Jan 1, 2021
This paper presents an RF-EMF exposure assessment combining measurements and deterministic 3D ray-launching simulations in a large indoor public library with high node density. It considers mmWave 5G FR2 at 28 GHz and Wi-Fi 802.11ay at 60 GHz under realistic operation conditions with varying user distributions. The…

This paper discusses how rising man-made EMF from modern wireless technologies motivates careful regulation to keep exposure below levels expected to cause harm. It argues current regulations may not strictly constrain EMF when multiple nearby devices transmit simultaneously. The authors propose a…
Electromagnetic Energy Absorption in a Head Approaching a Radiofrequency Identification (RFID) Reader Operating at 13.56 MHz in Users of Hearing Implants Versus Non-Users.

This modeling study estimated SAR in a head approaching a 13.56 MHz RFID HF reader, comparing hearing-implant users with non-users. The abstract reports that BAHA implants can increase localized SAR (10 g) versus non-users, up to 2.1× in a worst-case scenario, and that this increase is statistically higher than for…
MEASUREMENT OF EMF EXPOSURE AROUND SMALL CELL BASE STATION SITES.
Research
RF Safe Research Library
Jan 1, 2019
This paper reports a measurement program assessing RF EMF exposure around small cell base station sites. The authors note that relatively little exposure data are available for small cells compared with base stations in general. Measurements were compared with relevant safety guidelines and with existing base-station…
The role of the location of personal exposimeters on the human body in their use for assessing exposure to the electromagnetic field in the radiofrequency range 98-2450 MHz and compliance analysis: evaluation by virtual measurements

Jan 1, 2015
This study used numerical modeling with a human body model to evaluate how the placement of a single body-worn personal exposimeter affects RF electric-field measurements in the 98–2450 MHz range. Across 256 simulated exposure scenarios, the body substantially altered measured values compared with the unperturbed…

This exposure assessment measured unperturbed electric fields near antennas of 50 portable radiophones used by rescue and uniformed services. Occupational exposure-level field strengths (per Polish OSH safety-zone criteria) occurred tens of centimeters from antennas, and Directive 2013/35/EU action levels were…
Application of an induced field sensor for assessment of electromagnetic exposure from compact fluorescent lamps.
Research

Jan 1, 2012
This study investigates instrumentation and procedures to assess electromagnetic exposure from compact fluorescent lamps (CFLs) by measuring both incident and induced fields in the 10 kHz–1 MHz range. For some CFLs, incident electric fields exceeded ICNIRP reference levels at close distances, but induced fields were…
