Bluetooth Radiation – Bluetooth Health Risks

Given the debate flaring up on health dangers from cell phone use and Bluetooth radiation, a closer examination of some hard facts regarding Bluetooth dangers should not be unfitting. With all the new technology surrounding us, the effects of radiation which are yet quite unfathomed, one can never be too cautious about protecting himself from pointless exposure to health risks against cell phone radiation and Bluetooth headset radiation.  These points should be taken:

• Does Bluetooth radiation powerful enough to cause cancer?
• What about the distance from any point of transmission does it affects Bluetooth radiation?
• How safe are Bluetooth radiation from cell phone radiation?  Is there any point of difference?

Bluetooth Radiation – The Wireless Communication Physics

Is there really a bluetooth radiation? Wireless technology operates using the microwave (electromagnetic) frequency spectrum at a range typically varying from 0.24 to 1.8 GHz. For reference’s sake, microwave ovens operate at 2.45 GHz, while radio waves use a lower frequency range. The human body absorbs these frequencies when found near devices emitting them. The amount of energy taken in by human tissue is counted in Specific Absorption Rate (SAR) units, i.e. in watts per kilogram of bodily weight.  In the case of Bluetooth radiation it is called Bluetooth SAR.

Sensitive Ears: Why Cell Phone And Bluetooth Radiation Became An Issue

The first concerns were generated by reports about irritating symptoms, such as nausea, headaches, disturbances in sleep and mood, etc after exposure to cell phone radiation, as well as, low radiation Bluetooth headset. The individuals complaining about exposure symptoms were qualified as “sensitive” and the industry claimed that radiation exposure dangers were non-existent. Soon studies were published, suggesting that long-term exposure to cell phone radiation could have carcinogenic effects, resulting in the appearance of brain tumours. The issue is still debated, with much said on the pros and the cons of the dangers of Bluetooth and cellphone radiation.  Questioning the bluetooth radiation risk level to our mortality.

Bluetooth Radiation vs. Cell Phone Radiation:  The Low Radiation Headset

While no conclusive evidence exists yet on the alleged dangers of cell phones and no official agency is willing to declare them hazardous to human health, mere numbers suggest that Bluetooth radiation is significantly lower than the one emitted by mobile phones. In fact, a Bluetooth headset works at the 0.24 to 0.25 GHz frequency range, while a typical cell phone wavers from 0.9 to 1.8 GHz. Furthermore, the SAR levels emitted by most cells phones (and absorbed by the human body) are between 0.8 and 1.4 watts per kg, while the best Bluetooth headset may operate at no more than  a bluetooth radiation of 0.001 watt/kg. Also, the way in which radio signals are transmitted is radically different: a Bluetooth device diffuses its signals throughout space; on the other hand, a satellite’s radio signals reach your cell phone in the form of a single, definitely more powerful beam.  Thus, dangers of radio wave radiation through cellphones are more likely than Bluetooth radiation.

Bluetooth Radiation Expert Talk: What Official Agencies Say On the Issue of Health Precautions of Radio Waves

The Environmental Study Group, a Swiss Federal Office of Public Health, reports that mobile phone radiation can be 12 to 34 times higher than Bluetooth radiation.  And while the UK Health Protection Agency claims that no actual danger is posed by cell phone radiation, it admits that further studies must be carried out before reaching a definitive conclusion on Bluetooth cancer and cell phone cancer. And what about the U.S.A.? The FDA (Food and Drug Administration) has issued directives to cell phone manufacturers requiring proper notification to users about potential hazards to health and radiation from cordless phones. This requirement is not applicable to Bluetooth headsets, as the Bluetooth radiation levels are not associated with health issues.

Bluetooth Radiation – The Bluetooth Safety

Studies are still being conducted by State and private bodies, as well as by the wireless technology industry, to establish whether the alleged health risks are substantial enough for further measures to be taken for Bluetooth radiation. Until newer evidence emerges, existing data suggest that Bluetooth radiation is rather minimal in comparison with radiation emitted from cell phones, the use of these gadgets are still safe.
