nuclear radiation Flashcards
what are the three different types of radiation
alpha, beta and gamma
whats radioactivity
is the process that occurs when alpha particles, beta particles, or gamma waves are emitted from a unstable nucleus
what are alpha particles
particles that are helium nuclei containing two protons and two electrons which are emitted by radioactive nuclei
what are beta particles
particles that are fast moving electrons emitted by radioactive nuclei
what are gamma radiation
radiation is a high energy electromagnetic wave emitted by radioactivity
what are the particles and waves referred to
nuclear radiation
what is the disintegration called
radioactive decay
what is the alpha particle the nucleus of
helium
what do unstable nuclei emit when they disintegrate
they emit alpha, beta and gamma radiation randomly and spontaneously
