When considering the use of cell phones or other wireless electronic devices, it is important to understand how much Specific Absorption Rate (SAR) value is considered to be safe for the head and body. SAR values measure the rate at which energy is absorbed by the body when exposed to a radio frequency (RF) electromagnetic field. Knowing more about the amount of SAR absorbency that is considered to be safe can help you make educated decisions about the safety of your device use.
Introduction
When using electronic devices such as cell phones, it is important to know the SAR (Specific Absorption Rate) value associated with the device. SAR values measure the amount of radio frequency energy that a person absorbs when using a device. This is especially important for devices that are held close to the body, such as cell phones. In this article, we will discuss how much SAR value is safe for your head and body.
What is SAR?
SAR stands for Specific Absorption Rate, which is a measure of the rate at which energy is absorbed by the human body when exposed to a radio frequency (RF) electromagnetic field. The SAR value is measured in watts per kilogram (W/kg) and is a measure of the amount of RF energy absorbed by the body.
What is a safe SAR value?
The Federal Communications Commission (FCC) sets the maximum SAR value for cell phones at 1.6 W/kg. This means that if a cell phone has an SAR value of 1.6 W/kg or lower, it is considered safe for use. The SAR value of a cell phone can be found on the manufacturer’s website or in the user manual.
The World Health Organization (WHO) also recommends that people limit their exposure to RF energy from cell phones by using a hands-free device or keeping the phone at least 25 centimeters (10 inches) away from the body.
SAR Values for the Head
Since the head is the most sensitive area of the body, the FCC suggests that the SAR value for the head should be lower than for the rest of the body. The FCC recommends that the SAR value for the head should not exceed 1.6 W/kg.
SAR Values for the Body
The FCC recommends that the SAR value for the body should not exceed 1.6 W/kg. This means that any device that has an SAR value of 1.6 W/kg or lower is considered safe for use.
Conclusion
Overall, the SAR value of a device is an important factor to consider when using it. The FCC recommends that the SAR value for the head should not exceed 1.6 W/kg and that the SAR value for the body should not exceed 1.6 W/kg. It is important to check the SAR value of a device before using it to ensure that it is safe for use.
