Radiation can transmit, scatter, or absorb as it passes through matter. Learn how attenuation works — and why it's essential to understanding dose delivery in radiation therapy.
Excitation vs. ionization: two ways radiation interacts with atoms. Learn how each process works and why ionization is the key to understanding how radiation deposits dose in tissue.
Not all radiation is the same. Learn the key difference between particle and electromagnetic radiation — and why it shapes how we image, treat, and think about dose.
