View Original AbstractKeeping your phone even slightly farther from your head significantly reduces brain radiation absorption, making distance the simplest protection strategy.
Plain English Summary
Researchers used computer modeling to study how distance and angle between a cell phone and user's head affects SAR (specific absorption rate), which measures how much radiofrequency energy the head absorbs. They found that keeping the phone farther from your head significantly reduces SAR values, but changing the angle doesn't consistently help. This research provides practical guidance for reducing your exposure to cell phone radiation during calls.
Why This Matters
This engineering study reinforces a fundamental principle that many users overlook: distance is your friend when it comes to cell phone radiation. The science demonstrates that even small increases in distance between your phone and head dramatically reduce SAR values, which directly translates to less radiofrequency energy absorbed by your brain tissue. What makes this research particularly valuable is its practical focus on real-world phone positioning scenarios. While the telecommunications industry often emphasizes that phones meet SAR limits, this study shows you don't have to accept maximum allowable exposure levels. The reality is that simple changes in how you hold and position your phone can meaningfully reduce your exposure without requiring any special equipment or lifestyle changes.
Exposure Information
Specific exposure levels were not quantified in this study.
Study Details
The aim of this paper is to investigate the effects of the distances between the human head and internal cellular device antenna on the specific absorption rate (SAR). This paper also analyzes the effects of inclination angles between user head and mobile terminal antenna on SAR values.
The effects of the metal-glass casing of mobile phone on the SAR values were observed in the vicinit...
The results indicate that by increasing the distance between the user head and antenna, SAR values a...
