What Is SAR Value?
SAR stands for Specific Absorption Rate and is a measure of how much energy from an electromagnetic field is absorbed by the body. It’s usually measured in W/kg and is a way to compare different devices and how much radiation they emit.
What Are the Recommended Limits for SAR Value?
The World Health Organisation (WHO) and the International Commission on Non-Ionizing Radiation Protection (ICNIRP) have both set recommended safe limits for SAR value. The ICNIRP limits are the same for all frequencies, while the WHO limits differ depending on the frequency of the radiation.
The ICNIRP suggests that the SAR value should not exceed 0.08 W/kg, while the WHO suggests that the SAR value should not exceed 2 W/kg. It’s important to note however that these are only recommended limits and not necessarily the maximum allowable limits.
What Is the Difference Between the Two Limits?
The difference between the two limits is that the ICNIRP limit is the same for all frequencies, while the WHO limit is based on the frequency of the radiation. Generally speaking, the lower the frequency of the radiation, the higher the limit for the SAR value.
What Is the Difference Between SAR Value and Other Measures?
SAR value is a measure of how much energy from an electromagnetic field is absorbed by the body. This is different from other measures such as power density (which is a measure of the amount of energy produced by a device) and field strength (which is a measure of the intensity of the energy).
What Are the Potential Health Risks of Exceeding the Recommended Limits for SAR Value?
Exposure to high levels of radiation can lead to a range of health issues, such as headaches, fatigue, impaired memory and concentration, and even DNA damage. There is also some evidence that suggests that long-term exposure to radiation can increase the risk of certain types of cancer.
How Can I Reduce My Exposure to Radiation?
The best way to reduce your exposure to radiation is to keep your device away from your body as much as possible. You should also avoid placing your device in your pocket, on your lap, or near your head. Additionally, you can reduce your radiation exposure by using a hands-free headset.
Conclusion
The recommended limits for SAR value set by the World Health Organisation and the International Commission on Non-Ionizing Radiation Protection are 0.08 W/kg and 2 W/kg respectively. It’s important to note however that these are only recommended limits and not necessarily the maximum allowable limits. Exceeding these limits can lead to a range of health issues, so it’s important to take steps to reduce your exposure to radiation.
