Human body naturally has the ability to bear electromagnetic radiation but up to certain limit. Radiation beyond 500 millirems becomes harmful for human body. In current age of electronics, due to wide use of electronic goods, the amount of electromagnetic radiation in surrounding environment has increased much beyond the bearable limits. The use of at least some of the electronic goods is unavoidable. So, the question arises that how humans can protect themselves from harmful effects of electromagnetic radiation emitted by electronic appliances etc.
Sorry, but I don't get the "200 millirims" you mentioned. Do you mean "200 millirems"? If so, this is a normal occupational dose per year and not a limit were it becomes harmful.
Also you should be careful not to mix the unit of dose for the effects of ionizing radiation and electromagnetic radiation.
Thanks R. Schnell for pointing out. The typing mistake has been corrected.
shilding and distance!
You can shild the sources of electromagnetic radiation and you can keep as much as possible distance to the sources.
One should minimize the amount of time spent in high radiation areas.
