 This is a hypothetical radioactive decay graph If the half-life were shorter then the exponential decay graph would be steeper and the line would be decreasing at a faster rate therefore the amount of the radioactive nuclei would decrease as well Radioactive decay is not always a one step phenomenon Often times the parent nuclei changes ### Radioactive Decay And The Half Life Worksheets

This is a simulation of the radioactive decay of 400 radioactive nuclei You can choose from three different half lives Note that the nuclei turn blue when they have decayed and the smooth purple line on the graph shows the ideal case An actual case can deviate a bit from the ideal case because of statistical fluctuations (which make more of ### Radioactive Decay – The Physics Hypertextbook

beta decay Also called beta minus decay Quote that must be paraphrased The existence of neutrinos was first proposed by Wolfgang Pauli in a 1930 letter to his physics colleagues as a desperate way out of the apparent non-conservation of energy in certain radioactive decays (called beta decays) in which electrons were emitted According to ### Basic Physics of Nuclear Medicine/The Radioactive Decay

For our radioactive decay situation we first of all consider that we have a sample containing a large number of radioactive nuclei all of the same kind This is our unpopped corn in the pot for example Secondly we assume that all of the radioactive nuclei decay by the same process be it alpha beta or gamma-decay In other words our unpopped ### Radioactive Decay And The Half Life Worksheets

State the meaning of radioactive decay When a nucleus is unstable it will disintegrate (break up) This shoots out tiny particles and a burst of energy These materials are radioactive so the breaking up of the nucleus is called radioactive decay Each unstable nucleus changes into an isotope of a different element after radioactive decay Decay occurs slowly but surely According to a study by the Finnish nuclear safety authority upon removal from a reactor spent fuel is 4 million times more radioactive than the natural uranium from which it was made One year later this factor has fallen to 60 000 After 500 years the fuel is still 100 times more radioactive It takes 7 1 Gamma decay Gamma decay is the third type of radioactive decay Unlike the two other types of decay it does not involve a change in the element It is just a simple decay from an excited to a lower (ground) state In the process of course some energy is released that is carried away by a photon Similar processes occur in atomic physics Radioactive Decay Series The naturally occurring radioactive isotopes of the heaviest elements fall into chains of successive disintegrations or decays and all the species in one chain constitute a radioactive family or radioactive decay series Three of these series include most of the naturally radioactive elements of the periodic table
