1- The electromagnetic spectrum is the range of all type of EM radiation. It also describes the wavelength of light. EM radiation is the radiant energy that is released by a certain electromagnetic processes and a wavelength is the distance between successive crests of a wave. 2- The different between ionising and non-ionising radiation is that ionising radiation carries energy to ionize atoms and has more energy than non-ionising. Non-ionising is found at the end of a long wavelength where as ionising radiation is found at shorter wavelength. Regions of the spectrum: • Gamma radiation- ionizing • X-ray radiation- ionizing • Ultraviolet radiation- non-ionizing • Infrared radiation- non-ionizing • Microwave radiation- non-ionizing • Radio waves- non-ionizing 3- A) Lethal Dose Effects 5-20 Possible late effects; possible chromosomal damage 20-100 Temporary reduction in white blood cells 100-200 Mild radiation sickness within a few hours:…show more content…
Most smartphones use radio frequency which is allocated in the mobile service for their reception of their signals. B) Researches has indicated the health concerns of smartphones are cancer, other health effects and car accidents. The number of smartphones are increasing leading to health issues increasing. However, there is no current evidence to non-ionising radiation increasing cancer risk but according to World Health Organizing based on mixed epidemiology between radiation frequency from wireless phones and head cancers, researches has confirmed that smartphones have the potent to cause cancer to human from the radiofrequency energy that is heating. Smartphones also can muck up your sleeping pattern, change in brain activity and reaction times. Lastly smartphones are increasing the risk of a car accident, 3-4 times greater chance of having an accident when smartphones re in se while driving due to
