Which of the following statement regarding radioactive decay is correct?  Average life equals to 1.44 of half-life. Half-life is directly proportional to decay constant. The decay of element is proportional to no of atoms or moles.
Nuclear wastes is waste that contains radioactive material. Radioactive material is normally a by product of nuclear power generation. Radioactive waste is regulated by government agencies in order to protect human health and the environment. Radioactivity naturally decays over time, so radioactive waste has to be isolated and confined in appropriate disposal facilities for a sufficient period until it no longer poses a threat. Which of the following statements can be inferred from the paragraph?
