I thought I would indicate how radiactive decay can be argued to occur from quantum tunneling. This derives in a very “back of the envelope” way the phenomenological equation for radioactive decay. From there I can argue some about the role of observing radioactive decay. Quantum tunneling can be see with the square potential barrier. A square potential ...
There are no known transistors or oscillators yet produced that can handle 10^19 frequancies, we are still experimenting at terahertz range 10^12 or thereabouts so the simple answer is no.
The best way to differnciate is to look at the count-rate vs time graph. Random nature of radioactivity is indicated by the fluctuation of the count-rate. Whereas, spontaneous means that the process of radioactivity is not dependent upon any external environmental conditions like temperature, pressure, magnetic/electric field. For example: Plot a count rate ...
THe U238 nucleus is unstable and does undergo "ordinary" radioactive decay. For a U238 nucleus to undergo fission you need to provide the nucleus with something akin to an activation energy of about 7 MeV. One model is that the nucleus is like a liquid drop and adding a neutron can make the drop oscillate so much that it breaks up into two smaller pieces ...
