Understanding 5G's Role in SAR and Radiation Exposure
Mobile phones with 5G connectivity often have higher Specific Absorption Rate (SAR) values due to the higher frequencies they use. However, when you turn off the 5G network, you might wonder if you are still exposed to higher SAR radiation. This article aims to clarify the relationship between 5G, SAR, and radiation exposure, addressing common concerns and misconceptions.
What is Specific Absorption Rate (SAR)?
Specific Absorption Rate (SAR) measures the rate at which the body absorbs radiofrequency energy from devices such as mobile phones. The higher the SAR value, the more energy is absorbed by the body. SAR values are regulated by authorities in different countries to ensure they remain within safe limits.
Impact of 5G on SAR Values
While 5G networks do use higher frequency bands, turning off the 5G network on your mobile phone does not completely eliminate radiation exposure. The phone still emits radiofrequency energy when using other network technologies such as 4G, 3G, or Wi-Fi. Therefore, even though you have disabled 5G, the device itself may still release radiation.
How Turning Off 5G Affects Radiation Exposure
Turning off the 5G network on your mobile phone may reduce your exposure to higher-frequency radiation specific to 5G networks. However, your phone will still emit radiation when using other network technologies. In essence, you remain exposed to some level of SAR radiation even if the 5G feature is disabled. This is because the device itself continues to emit energy.
Penetrative Properties of Higher Frequencies
Some individuals are concerned about the higher frequencies used in 5G. However, it is important to note that higher frequencies are absorbed less by the body. For example, visible light, which has a higher frequency than radiofrequency, is not known to cause cancer or penetrate through opaque bodies. In fact, UV, X-rays, and gamma rays are the types of radiation that are more concerning due to their penetration and potential to damage tissues.
Myths and Realities About SAR Values
There are misconceptions about SAR values and their implications. Some believe that a higher SAR value means higher danger. However, SAR is a limit test where you either pass or fail. If your phone passes the SAR limit tests, it can be legally sold. There have been no definitive links found between phone use and health issues, although authorities set SAR limits out of caution.
Turning Off All Devices for Optimal Proximity
To further minimize radiation exposure, some people suggest turning off all electronic devices. While this might provide peace of mind, it is important to understand that all electronic devices emit some kind of field. Thankfully, many modern devices emit lower levels of radiation than older models. For instance, older TVs used to emit x-rays, and early cell phones were higher in power and continuous.
Conclusion
In conclusion, while disabling the 5G network on your mobile phone can reduce your exposure to 5G-specific SAR values, the benefits are limited as your phone will still emit some level of radiation when using other network technologies. Understanding the nature of SAR and the realities of modern electronic devices can help alleviate concerns about radiation exposure. For those who remain concerned, using features such as speakerphone or keeping the phone away from the body while in use can further reduce exposure.
