By: Esmeralda,Ryan T https://padlet.com/ctomkinson/y4wtpbbis1rd/wish/230673598 The dangers of radio waves can cause cancer,leukaemia and other disorders. Some people claim that very low frequency field from overhead power cables near their homes has affected their health, although this has not reliably proven. Radio waves can damage the DNA inside a cells, which can result as cancer Radiofrequency (RF) radiation, which includes radio waves and microwaves is at low-energy end of the electromagnetic spectrum. It is a type of non-lonizing radiation.

  • Radio waves have lower frequencies and longer wave lengths than microwaves. 
  • They are used to transmit television and radio programs.
  • You can’t visually see them.

  • Radio waves are considered to be one of the human most important discoveries as it made communication much more efficient 
  • Radio waves are electromagnetic waves, not sound waves as many people believe. 
  • Radio waves travel very fast -at the speed of light

    Discovery Scottish psyhicriast James Clerk Maxwell who delivered a unified theory of electromagnets in the 1870s predicted the existence of radio waves a few years later Heinrich Hertz actually invented it in 1870 in Scotland.]]>     2018-02-12 16:24:28 UTC https://padlet.com/ctomkinson/y4wtpbbis1rd/wish/230674886
