No, cell phones themselves do not emit dangerous radiation if you do not have one. Cell phones emit non-ionizing electromagnetic radiation, specifically in the form of radio waves. This type of radiation is considered to be relatively low energy and is not known to cause direct harm to human tissues or DNA.
However, it's worth noting that if you are in close proximity to someone who is actively using a cell phone, you may be exposed to the radio frequency energy emitted by their device. The level of exposure would be much lower than what the person using the phone experiences since the intensity of the radiation decreases with distance from the source.
The potential health effects of long-term exposure to radio waves from cell phones and other wireless devices have been the subject of scientific research. The consensus among scientific bodies, such as the World Health Organization (WHO), is that there is currently no conclusive evidence to support the claim that exposure to radio waves from cell phones at typical exposure levels causes adverse health effects. However, ongoing studies and research continue to explore any potential long-term effects.
If you have concerns about cell phone radiation, you can take precautionary measures such as using hands-free options (like speakerphone or a wired headset) or keeping the phone at a distance from your body when not in use. Additionally, using a cell phone with a lower specific absorption rate (SAR) value can help reduce exposure. SAR is a measure of the rate at which energy is absorbed by the body when exposed to radio frequency fields, and phones with lower SAR values emit less radiation.
