How to Use This Calculator
- Enter the frequency of the radio frequency source in MHz. This is typically found on the device specifications.
- Input the transmitted power of the source in milliwatts (mW). If not available, a typical value can be estimated.
- Specify the distance from the source in centimeters (cm). Measure from the center of the source to the location of interest.
- Click the "Calculate" button to determine the SAR value and exposure level.
Understanding SAR Values
The Specific Absorption Rate (SAR) measures how much radio frequency energy is absorbed by the body when exposed to a radio frequency source. It is expressed in milliwatts per gram (mW/g) of tissue.
Exposure Guidelines
The International Commission on Non-Ionizing Radiation Protection (ICNIRP) recommends that the maximum SAR exposure for the general public should not exceed 0.08 mW/g. This calculator provides a simple method to estimate SAR values for comparison with these guidelines.
Important Notes
- This calculator provides a simplified estimation of SAR values. For precise measurements, specialized equipment is required.
- The actual exposure may vary based on factors such as body size, position relative to the source, and the specific frequency characteristics of the device.
- For regulatory compliance purposes, consult official safety guidelines and standards specific to your region and application.
