The HPA also says that due to the mobile phone's adaptive power ability, a DECT cordless phone's radiation could actually exceed the radiation of a mobile phone. The HPA explains that while the DECT cordless phone's radiation has an average output power of 10 mW, it is actually in the form of 100 bursts per second of 250 mW, a strength comparable to some mobile phones.
Much of the current debate is about relatively low levels of exposure to radio frequency (RF) radiation from mobile phones and base stations producing "non-thermal" effects. Some experiments have suggested that there may be biological effects at non-thermal exposure levels, but the evidence for production of health hazard is contradictory and ...
A new review of previous research determines if cell phone radiation causes brain cancer. The review concludes that radiation from cell phones is not likely to increase a person’s risk of brain ...
Mobile phones continue to become more multifunctional and sophisticated, which exacerbates the problem. [47] In 2014 the BBC reported concerns from opticians regarding blue-violet light emitted by cell phone screens, that it may be potentially hazardous to the eye and long term it may possibly increase the risk of macular degeneration. [48]
A new study released Wednesday in the Journal of the American Medical Association revealed that 50 minutes of continuous cell phone use causes temporary changes in the brain. That period of cell ...
Another important factor is the distance between the worker and the source of radiation. In the case of arc welding, infrared radiation decreases rapidly as a function of distance, so that farther than three feet away from where welding takes place, it does not pose an ocular hazard anymore but, ultraviolet radiation still does. This is why ...
Ionizing radiation (US, ionising radiation in the UK), including nuclear radiation, consists of subatomic particles or electromagnetic waves that have sufficient energy to ionize atoms or molecules by detaching electrons from them. [1]
Radiation is often categorized as either ionizing or non-ionizing depending on the energy of the radiated particles. Ionizing radiation carries more than 10 electron volts (eV), which is enough to ionize atoms and molecules and break chemical bonds. This is an important distinction due to the large difference in harmfulness to living organisms.
