Virtual reality (VR) headsets, 5G device, expose electromagnetic radiation to the human head led to concerns about the health effects. The purpose of this study is to predict the specific absorption rate (SAR) due to VR headsets in the human head. The study involves two biological models. Model A is a flat specific anthropomorphic mannequin (SAM). Model B is Model A inserted with a designed brain. The results are found that the SAR of model B is higher than that of model A, under the standard limits and not affected by temperature, short term memory, or memory load.
Urządzenia wirtualnej rzeczywistości generują pola elektromagnetyczne. W artykule analizowano współczynnik SAR takich urządzeń dla dwóch modeli.
