The nucleus is too large to be stable. There is the theory of grouping of nucleons into alpha particles inside the nucleus and, through oscillations of the nucleus, one of these on one end of the nucleus can be repelled with a great enough force to push it out of the nucleus.

Many radioactive isotopes are more radioactive than the naturally occurring uranium isotopes:All fission product isotopes are more radioactive (e.g. iodine-131, strontium-90)Most radioactive isotopes in the uranium --> lead decay chain are more radioactive (e.g. radium, radon, polonium)Plutonium is more radioactiveTritium is more radioactiveCarbon-14 is more radioactiveArtificially produced uranium isotopes are more radioactive (e.g. uranium-233, uranium-236)etc.
Radon is a radioactive gas that can cause cancer.
That'd be radon
The process of a radioactive decay is atomic nucleus of an unstable atom loses energy by emitting ionizing particles
See the link below for radioactive decay chains.
Alpha decay
Radium naturally decays into radon, which is a radioactive noble gas. This decay process is one of the steps in the radioactive decay chain of uranium-238.
Uranium is radioactive because it is an unstable element with a nucleus that can undergo radioactive decay. During this decay process, uranium releases energy in the form of alpha, beta, or gamma radiation as it transforms into other elements over time. This radioactive decay is what makes uranium useful for nuclear energy and weapons.
Only the end product of the decay chain of uranium, a non radioactive isotope of lead.
Yes, the radioactive decay of Uranium-235 is used to produce power in nuclear power plants.
Alpha decay
Heating radioactive uranium would not make it decay faster because the decay rate of a radioactive material is a fundamental property of that specific isotope and is not affected by external factors like temperature. The decay rate of uranium is governed by its half-life, which is a constant characteristic of the isotope. Heating the uranium would not alter this intrinsic property and thus would not impact the decay rate.
- radioactive decay - nuclear fission - nuclear reactions
Uranium undergoes radioactive decay and emits alpha particles which can damage tissue.

This is an alpha decay.
