In order for an atom of an element that is not radioactive to become radioactive, the isotope has to change. This can happen as a result of neutron capture.
Neutron capture can simply change the isotope of an atom, as when cobalt-59, which is not radioactive, captures a neutron to become cobalt-60, which is radioactive.
Neutron capture can also result in immediate radioactive decay of the atom struck, even if it is not radioactive. For example helium-3 can capture a neutron to produce two atoms of hydrogen, one of hydrogen-3 and one of hydrogen-1.

Which elements found in nature have mainly radioactive isotopes?
Some elements found in nature that mainly have radioactive isotopes include uranium, thorium, and potassium. These elements have naturally occurring radioactive isotopes that decay over time, releasing energy in the form of radiation.
How is a radioactive isotope different from a stable isotope?
The radioactive isotope is disintegrated in time and emit radiations.
What are properties of radioactive elements?
Radioactive elements undergo spontaneous decay, emitting radiation in the form of alpha, beta, or gamma particles. They have unstable nuclei and decay into more stable elements over time. Radioactive elements are used in various applications such as medical imaging, cancer treatments, and energy production.
What is radio active substance?
A radioactive substance is a material that contains unstable atomic nuclei, which decay over time and emit radiation in the form of particles or electromagnetic waves. This process, known as radioactive decay, can result in the transformation of the substance into different elements or isotopes. Common examples include uranium, radium, and thorium. Radioactive substances are used in various applications, such as medical treatments, nuclear power generation, and scientific research.
What is the difference between and radioactive and stable isotope?
Radioactive isotopes emit radiation in the form of alpha, beta, positron or gamma rays to become a stable isotope of any given particular element. This is caused by the instability of the nucleus of the atom. The stabilising process in which unstable atoms undergo is known as radioactive decay. Isotopes that are stable do not emit radiation. For example; Carbon-12 is stable and carbon-14 is radioactive.
Does radiation contamination fade over time?
Sure but it depends on the radioactive elements halflives
Why only radioactive element give out radiation?
It's a semantic thing - by definition, if something gives out radiation, then it is radioactive. If an element gives off radiation, then it is a 'radioactive' element. If it does not give out radiation, then it is not 'radioactive'.
Difference between a non-radioactive substance and a radioactive substance?
Radioactive elements are unstable and will decay into other elements in a decay chain. Non-radioactive elements are stable and won't commence into radioactive decay. Radioactive elements can be found from atomic number 84 onwards.
How does fission create radioactive waste?
During fission, atoms split into smaller fragments, releasing energy and neutrons. Some of these fragments are radioactive isotopes, which emit radiation and decay over time, creating radioactive waste.
Which elements found in nature have mainly radioactive isotopes?
Some elements found in nature that mainly have radioactive isotopes include uranium, thorium, and potassium. These elements have naturally occurring radioactive isotopes that decay over time, releasing energy in the form of radiation.
How is a radioactive isotope different from a stable isotope?
The radioactive isotope is disintegrated in time and emit radiations.
How is radioactive Isotope different from a stable isotope?
The radioactive isotope is disintegrated in time and emit radiations.
List of radioactive elements?
Elements that decay (give off protons and neutrons) to form other elements. *It's not elements as such that are stable or unstable, but rather isotopes. Even elements of small atomic number have unstable isotopes that undergo radioactive decay, for example carbon-14. Elements with higher atomic numbers than Lead (82) are naturally radioactive in all isotopes. Bismuth (83) has an extremely long half-life, but the time generally becomes shorter (the decay more rapid) as the size of the nucleus gets progressively larger for heavier radioactive elements.
What are radioactive elements on the periodic table?
Some examples of radioactive elements on the periodic table include uranium, thorium, radium, and plutonium. These elements have unstable atomic nuclei that decay over time, emitting radiation in the process.
How many radioactive elementsare found in nature?
There are over 340 naturally occurring radioactive elements, but only around 70 of these are found on Earth in measurable amounts. These elements have unstable nuclei that decay over time, emitting radiation in the process.
