The same laws and rules are valid for radioactive natural and artificial isotopes.
I don't think there's a certain type as such. Selection and Elimination can be structured or random. Random is self-explanatory, structured, is based on the individual/the criterion, i.e. I will pick all the green and red Easter eggs out of a packet, etc.
In some cases, the direction of evolution is intentionally controlled by humans. We call this artificial selection, or breeding - as in the breeding of cattle. In all other cases, nobody controls the direction of evolution.
Artificial selection tends to occur more quickly than natural selection because it involves intentional breeding by humans to promote desired traits in organisms. This focused approach can lead to rapid changes in specific characteristics over a few generations. In contrast, natural selection operates through environmental pressures and can take much longer for significant changes to occur, as it relies on random genetic variations and survival advantages over time.
Lack of a selection factor. In the absence of selection pressure from natural, sexual or artificial sources, the propagation of random genes would increase. Mutation rates may also be tuned to optimise genetic drift (emphasis on may!).
Mutations are random occurrences because they result from changes in the genetic material that are typically spontaneous and not influenced by any specific goal or plan. They can happen due to various factors such as exposure to mutagens or errors during DNA replication. As such, mutations are not a deliberate or controlled process but rather a natural phenomenon that contributes to genetic diversity.

No. Natural selection is the non-random survival of randomly varying replicators. The random variation part could be thought of as mutation and recombination that the non-randompart, natural selection, works with.

Natural light sources and artificial sources emit light with orientations of the electric vector that are random in space and time, thus proving to be nonpolarized.

Random variation refers to the natural variability observed in data that arises due to chance or random factors. It can impact the results of experiments, making it important to account for this variability when drawing conclusions from data. Random variation is often controlled for using statistical methods to ensure that patterns or effects observed are not simply due to chance.

Radioactivity depends on subatomic processes, and those are inherently unpredictable. The "why" is difficult to answer; but it seems that's the way our Universe works. You can calculate probabilities only.
Natural selection is the non-random survival of randomly varying replicating organisms.
