That is gamma decay, which is caused by a change in energy levels within a nucleus, but which does not result in any change to the number of protons or neutrons. A nucleus of one particular isotope can have different energy levels, these are called isomers of that isotope. The gamma radiation is electromagnetic, similar to x-rays but a higher frequency and hence higher energy.
The most important is the half life; also the type of decay, energy of released particles.
Particles or electromagnetic radiation are emitted.
During two types of radioactive decay an element is converted into another, 1- beta decay, during this decay a new element is formed with increase of one unit in atomic no but having the same atomic mass, 2- alpha decay converts the element into another having two units less in atomic no and four unit less in atomic mass.
1. Naturally astatine is found in the decay series of uranium, thorium and actinium. 2. Artificially astatine is prepared by nuclear reactions between bismuth and alpha particles with very strong energy.
Yes, decay is the process releasing energy by "burining" by living organisms.
Radioactive decay.
If atoms are radioactive, they can emit alpha,beta, or gamma radiation. The energy of the particles or rays emitted depends on the exact isotopes concerned, and varies widely from one to another.
Beta Particles
All nuclear decay releases both energy and particles. Even gamma rays from the meta stable decay of Technetium-99m, being only photons, are particles, because a photon is considered a particle - or is it energy? - or is it mass? - hmmm? - see quantum mechanics on that one.Also, Einsten's famous mass energy equivalence equation e = mc2 states rather plainly that energy is mass and mass is energy. That means that if nuclear decay releases energy, then it also releases mass, and vice versa. There is no way around the equivalence.Do not misunderstand this. The equation does not mean that energy can be converted into mass or vice versa, it means that energy is mass and vice versa. Neither energy nor mass can be created nor destroyed. So, when an atomic bomb goes off and loses mass generating a high amount of energy, the mass that is lost is simply carried away with the energy.Sorry if it seems I deviated from the topic, but I did not. This is part of reinforcing the answer and enhancing the explanation.
This is a gamma-decay.

Gamma decay don't affect the atomic number.
it emits very high energy photons
Huh?
because it releases energy, neutrons and neutrinos.

The end point energy of a beta decay is the kinetic energy of all particles emitted through B-decay. This is often ignoring the energy of the recoiling daughter nucleus.
