that depends on how you define dangerous.
Yes, alpha decay occurs naturally, that is why radioactive material is dangerous, because we can't simply "turn off" the radioactive decay.
If it is related to Nuclear studies, then the answer would be fusion.

The process where an element turns to another is radioactive decay, and exposure to radioactivity is dangerous.
alpha decay
radioactive decay
There are three types: Beta decay, alpha decay, and gamma decay/gamma rays. They are all dangerous if exposed to a high amount of radioactive matter. When the radioactive isotope undergoes beta, alpha, and gamma decay, there is an emission of a beta particle, alpha particle, and gamma ray (respectively). In highly radioactive matter, there are often trillions of radioactive isotopes that emit these particles and/or rays - and they are very high-energy once emitted. However, they are only dangerous when exposed to a high amount.
What type of reaction produces the most dangerous radioactive waste?
Technetium is not really dangerous. Since doctors will often use Technetium 99 as a radioactive tracer. It may be radioactive but its decay is slow and will produce a minute amount of gamma rays.
Most types of radioactive decay cannot be affected by anything. However, radioactive decay involving electron capture will be affected by the removal of electrons from around the nucleus. In the absence of orbital electrons, it cannot occur at all.
The fuel core could overheat from radioactive decay and lead to a meltdown.
No, most isotopes are not stable. Many isotopes are radioactive and decay over time, releasing radiation in the process. Only a few isotopes are stable and do not undergo radioactive decay.
