Wireless device radiation and health
Wireless device radiation and health is a topic of ongoing scientific research and public concern. The use of wireless devices such as mobile phones, Wi-Fi routers, and Bluetooth devices has increased dramatically in recent years. These devices emit electromagnetic radiation in the radio frequency (RF) range, and there is ongoing debate about whether long-term exposure to this type of radiation can cause adverse health effects.
Overview[edit | edit source]
Wireless devices communicate by transmitting and receiving signals in the radio frequency (RF) range of the electromagnetic spectrum. This is a type of non-ionizing radiation, which means it does not have enough energy to ionize atoms or molecules or remove tightly bound electrons. However, it can cause heating effects, and there is ongoing research into whether it can cause other types of biological effects.
Health effects[edit | edit source]
The World Health Organization (WHO) has stated that "to date, no adverse health effects have been established as being caused by mobile phone use." However, the WHO also notes that studies are ongoing to assess potential long-term effects. The International Agency for Research on Cancer (IARC), a part of the WHO, has classified RF fields as "possibly carcinogenic to humans," based on an increased risk for glioma, a type of brain cancer, associated with wireless phone use.
Safety standards and regulations[edit | edit source]
In many countries, safety standards and regulations have been established to limit RF exposure from wireless devices. These standards are based on the specific absorption rate (SAR), a measure of the rate at which energy is absorbed by the human body when exposed to a RF electromagnetic field. The SAR for a specific device can vary depending on how it is used and how it is held relative to the body.
