7.4 understand that alpha and beta particles and gamma rays are ionising radiations emitted from unstable nuclei in a random process
alpha particles, beta particles and gamma rays are all types of radiation.
The term ionising means they damage cells.
Radiation is emitted from the nucleus of an atom that is unstable (in a way it is too full and trying to off load.)
ionising radiation means that the radiation particles can convert other substances such as atoms and molecules into ions by knocking electrons out of the particles to form charged ions x

ReplyDeletelmao 3 hours till the exam and just started revising XD
ReplyDeleteIonisin radiation is radiation which has enough energy to collide with other atoms and dislodge their electrons turning them into ions
