Dictionary » R » Radiation Radiationradiation (Science: radiobiology) propagation of energy through space. In the context of this report, it is electromagnetic radiation (x-rays or gamma rays) or corpuscular radiation (alpha particles, electrons, protons, neutrons) capable of producing ionisation. The spread of a group of organisms into new habitats.A radial arrangement of nerve fibers connecting different parts of the brain.(medicine) the treatment of disease (especially cancer) by exposure to radiation from a radioactive substance.Syndrome resulting from exposure to ionizing radiation (e.g., exposure to radioactive chemicals or to nuclear explosions); low doses cause diarrhea and nausea and vomiting and sometimes loss of hair; greater exposure can cause sterility and cataracts and some forms of cancer and other diseases; severe exposure can cause death within hours; he was suffering from radiation.The spontaneous emission of a stream of particles or electromagnetic rays in nuclear decay.Electromagnetic energy that travels at the speed of light. ![]()

Re: Could it not be achieved in a controlled environment? They have been doing this but instead of intense sunlight radiation and heat they are using electrical current to provide energy. This technique has already synthesized many organic molecules from basic elements.
