Ionizing radiation consisting of alpha particles, emitted by some substances undergoing radioactive decay.
- Long before artificial probes were available, subatomic researchers such as Rutherford relied on concentrated alpha radiation.
- Capturing neutrons causes the boron nuclei to break apart, resulting in the emission of alpha radiation and lithium nuclei.
- After the boron is selectively localized to the tumor, it is irradiated with neutrons that cause the release of alpha radiation from the boron atoms.
