The field strength of electromagnetic radiation is measured in volts per meter (V/m). [ 2]: 139. The most common health hazard of radiation is sunburn, which causes between approximately 100,000 and 1 million new skin cancers annually in the United States. [ 3][ 4] In 2011, the World Health Organization (WHO) and the International Agency for ...

Environmental noise is an accumulation of noise pollution that occurs outside. This noise can be caused by transport, industrial, and recreational activities. [ 1] Noise is frequently described as 'unwanted sound'. Within this context, environmental noise is generally present in some form in all areas of human, animal, or environmental activity.
Noise pollution, or sound pollution, is the propagation of noise or sound with ranging impacts on the activity of human or animal life, most of which are harmful to a degree. The source of outdoor noise worldwide is mainly caused by machines, transport and propagation systems. [ 1][ 2][ 3] Poor urban planning may give rise to noise ...
