Samsung Galaxy S23 Ultra SAR Level: Understanding the Cellular Radiation Exposure Smartphones have become an essential part of our daily lives. We use them for communication, entertainment, and even our professional lives. With the increasing use of smartphones, concerns about the potential health risks of cell phone radiation have also risen. The Specific Absorption Rate (SAR) of a mobile device measures the amount of radio frequency energy absorbed by the body when using the device. The SAR values for the Samsung Galaxy S23 Ultra (FCC ID A3LSMS918B) are: 0.98 W/kg when held at the head 1.10 W/kg when worn on the body 1.20 W/kg when used as a hotspot or Airplay 1.59 W/kg at the head and on the body with simultaneous cellular and Wi-Fi transmission 1.54 W/kg when used as a hotspot simultaneously with other transmitters active. It’s important to note that the World Health Organization (WHO) has classified cell phone radiation as a Class 2 B Carcinogen, meaning it is “possibly carcinogenic to humans.” To reduce the potential health risks associated with cell phone radiation, it’s essential to take steps to reduce exposure, such as using hands-free devices and keeping the phone away from the body. In conclusion, while the SAR values of the Samsung Galaxy S23 Ultra are lower than the limits set by regulatory bodies, it’s still important to be mindful of your cell phone usage and take steps to reduce radiation exposure.
