Radioactive decay is the spontaneous change or disintegration of an unstable atomic nucleus as it transforms itself to lose energy. It does this by the release of either particulate radiation or electromagnetic radiation, or both. This atomic event is random and cannot be predicted, but by applying statistical principles to large numbers of a given radionuclide, an "average" decay time can be found, and we have the half-life. There are several different types of radioactive decay. They range from spontaneous fission to alpha decay, beta decay and a couple of others.

Are there any non examples of radioactive decay?

Nuclear fusion and nuclear fission are processes that involve nuclear reactions but are not examples of radioactive decay. Chemical reactions, such as burning wood, do not involve nuclear processes and are also not examples of radioactive decay.

What is the toxic radioactive metallic element that occurs in small quantities as a decay product of uranium?

All the decay chain isotopes are radioactive and toxic (excepting the last member which is non-radioactive but also toxic); you think probably to radium or polonium.

How is the radioactive decay of Krypton different from the radioactive decay of Americium?

The radioactive decay of americium 241 is by alpha disintegration; the disintegration of radioactive krypton isotopes is by beta particles emission.


What must occur before a radioactive atoms ceases to undergo further radioactive decay?

Before a radioactive atom ceases to undergo further radioactive decay, it must reach a stable configuration or decay into a non-radioactive isotope through the emission of particles or energy. This process continues until the atom reaches a state of stability where it no longer emits radiation.


What term indicates the process in which unstable nuclide release radiation?

If it is related to Nuclear studies, then the answer would be fusion.


When a radioactive nucleus decays and forms a new nucleus is the new nucleus always radioactive?

No. A stable nucleus can form. If the new nucleus is radioactive, then it will contiue to decay until a non radioactive nucleus is attained.


What is lost during radioactive decay?

Decay energy is the energy that has been freed during radioactive decay. When radioactive decay is ongoing it drops off some energy by means of discharging radiation.
