sukhi 2 Report post Posted June 10, 2010 Do you think organisms /plants and even humans emit radiation ? this is defintion of radiation below from wikipedia : " In physics, radiation describes any process in which energy travels through a medium or through space, ultimately to be absorbed by another body. Non-physicists often associate the word ionizing radiation (e.g., as occurring in nuclear weapons, nuclear reactors, and radioactive substances), but it can also refer to electromagnetic radiation (i.e., radio waves, infrared light,visible light, ultraviolet light, and X-rays) which can also be ionizing radiation, to acoustic radiation, or to other more obscure processes. What makes it radiation is that the energy radiates (i.e., it travels outward in straight lines in all directions) from the source. This geometry naturally leads to a system of measurements and physical units that are equally applicable to all types of radiation. Some radiations can be hazardous. " Clearly organisms dont emit radiation but there is a question here to all : There could be undiscovered radiations from the body which we have not been able to quantify. Historically electro magnetic radiations were predicted theoritically and then later on many years they were actually discovered. I must say there could be an alternate science for measuring those radiations. 1 OpaQue reacted to this Share this post Link to post Share on other sites
rvalkass 5 Report post Posted June 10, 2010 Clearly organisms dont emit radiation... You do, actually. Assuming you are a perfect black-body emitter at a body temperature of 310K you emit radiation at a peak wavelength of 9.35x10-6 m. This wavelength falls within the mid infrared region of the spectrum. Share this post Link to post Share on other sites

Lol i also thought the same at a later time after the post that we do emit Infra Red radiation or energy but the thing is that is more of an outcome of our energy in the body. What I try to say is there any rays being emitted from the body that would be sent out to communicate something to the environment and get some feedback for the same. Something like the bats using the auditory waves for seeing around couldbe called a radiation emitting from them. Share this post Link to post Share on other sites
