How does a sample of radioactive waste decay to a nonhazardous level?
All radioactive material has a characteristic half-life. This is a period during which half the matter from the original mass will have decayed into a daughter element. Either the daughter element is non-radioactive and therefore non-hazardous or it is radioactive and has its own half-life. The total radioactivity thus reduces over time and at some stage is deemed to reach a non-hazardous level.
Which statement is true about half-lives a Different atoms of the same element have different half-lives. b Each radioactive isotope has its own half-life. c All radioactive nuclides of an element?
The correct answer is: Half-lives are not affected by temperature.
Do radioactive elements have their own half life?
Yes, each one is unique.
