Aluminum isn't exactly some rare element, though... Is it the case that only a very small fraction of the aluminum atoms will capture an alpha particle, and/or that the positrons emitted from the 30P are very low energy, so the induced radioactivity is negligible? From my understanding...

Most general sources that describe the basics of ionizing radiation assert that the only type of radiation that can directly make other materials radioactive is neutron radiation (via "neutron activation"). Googling "does radiation make things radioactive?" produces a few examples, for...
