🛡️Anti-radiation stickers and devices claim to protect us from radiation exposure.
⚠️These products are meant to shield us from the radio frequency electromagnetic field (RF EMF) emitted by wireless devices.
💼Sales of anti-radiation products have increased in recent years.
❓Many people are unaware of what RF EMF is and the risks associated with it.
💡RF exposure is non-ionizing and considered safe within certain limits.
Do phones emit dangerous levels of radiation?
—Phones emit radio frequency electromagnetic fields (RF EMF), but the levels are regulated and considered safe within certain limits.
Do anti-radiation stickers and devices really work?
—There is no scientific evidence to support the effectiveness of anti-radiation stickers and devices in protecting against radiation exposure.
What is the specific absorption rate (SAR)?
—SAR measures the rate at which the body absorbs radio frequency energy when exposed to a device. Phones must be designed and operated below certain SAR levels to meet safety guidelines.
Is RF EMF exposure harmful?
—RF EMF exposure is considered safe within certain limits and is not classified as carcinogenic. However, prolonged and excessive exposure can lead to heating of body tissues.
Is distance from a signal source important?
—Yes, distance plays a crucial role in reducing RF EMF exposure. Moving further away from a signal source significantly reduces the power density of the radiation.
