Detailed explanation-1: -Uranium atoms decay into other atoms, or radionuclides, that are also radioactive and commonly called “decay products.” Uranium and its decay products primarily emit alpha radiation, however, lower levels of both beta and gamma radiation are also emitted.

Detailed explanation-2: -The radioactive decay series of 232Th is complex and produces alpha, beta, and gamma radiation. The figure below shows the important isotopes in the decay series, indicates whether the primary decay mode is via alpha or beta emission, and gives the half-life.

Detailed explanation-3: -What are Radioactive elements? Some elements of atomic nuclei are unstable because of the presence of excess nuclear charge inside it, so these nuclei undergo radioactive decay to form stable nuclei. These elements are called radioactive elements.

Detailed explanation-4: -Radioactive decay is the process in which an unstable nucleus spontaneously loses energy by emitting ionizing particles and radiation. This decay, or loss of energy, results in an atom of one type, called the parent nuclide, transforming to an atom of a different type, named the daughter nuclide.
