Negative values are always cut off. If you're using a cut off value of 10 and set the energy to -100, that negative energy will be deleted, although its actual amount is 100. Think of it like energy that just orients in the other direction, but has same power as +100. Like voltage.
As far as I can see, only radioactivity_cron() would have to be changed to handle cut off of negative energy properly. However, I am not sure, if other problems with negative energy can arise, since this doesn't seem to have been a requirement during development of the module.
