Evaluation of Specific Absorption Rate as a Dosimetric Quantity for Electromagnetic Fields Bioeffects

Evaluation of Specific Absorption Rate as a Dosimetric Quantity for Electromagnetic Fields Bioeffects

PURPOSE To evaluate SAR as a dosimetric quantity for EMF bioeffects, and identify ways for increasing the precision in EMF dosimetry and bioactivity assessment. METHODS We discuss the interaction of man-made electromagnetic waves with biological matter and calculate the energy transferred to a single free ion within a cell. We analyze the physics and biology of SAR and evaluate the methods of...

Specific absorption rate reduction using nonlinear gradient fields.

The specific absorption rate is used as one of the main safety parameters in magnetic resonance imaging. The performance of imaging sequences is frequently hampered by the limitations imposed on the specific absorption rate that increase in severity at higher field strengths. The most well-known approach to reducing the specific absorption rate is presumably the variable rate selective excitati...

The Ability of GSM Mobile Phone Users in Detecting Exposure to Electromagnetic Fields and the Bioeffects of These Fields on their Vital Signs

Background & Aims: Since previous studies on complications resulting from exposure to electromagnetic fields emitted by mobile phones are based only on self- reported symptoms, this study was performed to find the capability of users in recognition of real/ sham microwave exposure and probable alterations of vital signs after microwave exposure. Methods: In a two- step screening, from 700 stude...
