Among ionising radiation, alpha and beta particles are charged particles that have widely attracted research attention because of their use in a number of applications including smoke detectors, ...
Radiation is energy that moves from one place to another in a form that can be described as waves or particles. We are exposed to radiation in our everyday life. Some of the most familiar sources of ...
Actinium-225 is an alpha emitter, spewing out tiny bundles of energy that promise to kill cancer cells, but only at short range. This isotope and others like it are the focus of a ...
