Do you still maintain that there are exceptions to the "Law" of Cause and Effect?
You mentioned radioactive decay as a phenomenon without a cause. While I believe that the supernatural exists and breaks the laws of physics, I do not believe in physics that have "spooky" at a distance and unexplainable uncaused events. I checked up on decay. It seems the molecule is unstable but needs an underlying cause to trigger the decay.
Quantum vacuum fluctuations appears to be the "cause". Just as I explained with the gas laws one cannot know when a molecule hits a specific spot, only that given enough time it will happen.

The decay process, like all hindered energy transformations, may be analogized by a snowfield on a mountain. While friction between the ice crystals may be supporting the snow's weight, the system is inherently unstable with regard to a state of lower potential energy. A disturbance would thus facilitate the path to a state of greater entropy; the system will move towards the ground state, producing heat, and the total energy will be distributable over a larger number of quantum states thus resulting in an avalanche. The total energy does not change in this process, but, because of the second law of thermodynamics, avalanches have only been observed in one direction and that is toward the "ground state" — the state with the largest number of ways in which the available energy could be distributed.
Such a collapse (a gamma-ray decay event) requires a specific activation energy. For a snow avalanche, this energy comes as a disturbance from outside the system, although such disturbances can be arbitrarily small. In the case of an excited atomic nucleus decaying by gamma radiation in a spontaneous emission of electromagnetic radiation, the arbitrarily small disturbance comes from quantum vacuum fluctuations.
Do you have another example of effect without a cause?
