Chemistry alpha decay
Webradioactivity: Measurement of half-life. Half-lives are characteristic properties of the various unstable atomic nuclei and the particular way in which they decay. Alpha and beta decay are generally slower processes than gamma decay. Half-lives for beta decay range upward from one-hundredth of a second and, for alpha decay, upward from about ... WebWatch alpha particles escape from a polonium nucleus, causing radioactive alpha decay. See how random decay times relate to the half life.
