how did it originate?
Rutherford and his student Frederick Soddy were the first to realize that many decay processes resulted in the transmutation of one element to another. Subsequently, the radioactive displacement law of Fajans and Soddy was formulated to describe the products of alpha and beta decay.

where can helium be found in the world Most helium on Earth is a result of radioactive decay. Helium is found in large amounts in minerals of uranium and thorium, including uraninite and its varieties cleveite and pitchblende, carnotite and monazite. what are some of its uses? The largest use is in cryogenic applications, most of which involves cooling the superconducting magnets in medical MRI scanners and NMR spectrometers. who discovered it? Astronomer Jules Janssen when was it discovered? August 18, 1868 is this element hazardous? Neutral helium at standard conditions is non-toxic, plays no biological role and is found in trace amounts in human blood. When a person speaks after inhaling helium gas, it  causes a change in timbre of the amplified sound, resulting in a reedy, duck-like vocal quality. what exactly is the decay that you mentioned earlier? It  is the process by which an unstable atomic nucleus loses energy by radiation. A material containing unstable nuclei is considered radioactive. what are its type? Three of the most common types of decay are alpha decay, beta decay, and gamma decay is the first type used in any technology? UNANSWERABLE what are some of the health dangers related to the decay? The dangers of ionizing radiation due to radioactivity and X-rays were not immediately recognized.

Radioactive decay [SEP] History of discovery
It became clear from these experiments that there was a form of invisible radiation that could pass through paper and was causing the plate to react as if exposed to light. At first, it seemed as though the new radiation was similar to the then recently discovered X-rays. Further research by Becquerel, Ernest Rutherford, Paul Villard, Pierre Curie, Marie Curie, and others showed that this form of radioactivity was significantly more complicated. Rutherford was the first to realize that all such elements decay in accordance with the same mathematical exponential formula. Rutherford and his student Frederick Soddy were the first to realize that many decay processes resulted in the transmutation of one element to another.
