Abstract

Cellular devices are used globally by billions of individuals all around the world. These devices emit non-ionzing radiofrequency radiation (RFR), which has been associated in previous studies with potential adverse health effects following prolonged exposure. Depsite behavorial reccomendations to limit exposure, as of right now there is no practical and widely applicable solution that allows users to reduce RFR exposure while maintaing normal phone functionality. This study investigated the effectiveness of integration radiation-shiekdibg materials into phone cases as a method to reduce RFR emitted from a cellular device. Phone cases integrated with copper, aluminum, and steel were designed and tested using a Samsung Galaxy A35. Radiofrequency radiation levels were measured in miliwatts per square meter (mW/m²) using a radiofrequency meter and compared to a control case with no shiekding materials across 30 trials per group. A one-way ANOVA and post-hoc Tukey test were conducted to evaluate statistical significance. Results indicated that all three shielding materials reduced RFR emissions compared to the control; however, copper and aluminum showed the greates reduction overall, decreasing the measured RFR levels by approximately 80%. Steel provided a materate reduction, however, it was not as effective as copper and aluminum. Statistical analysis confirmed that the differences between the control and experimental groups were significant, as a p value of less than 0.05 was yielded. These findings support the hypothesis that integrating conductive shielding materials into phone cases can significantly reduce RFR emissions. The study suggests that phone cases integrated with shielding materials may be a practical approach for reducing user expsoure to radiofrequency radiation during everyday cellular device use.
