What is background radiation?
the time required for one half of a sample of a radioactive sample have decayed,while the other half remain unchanged
nuclear radiation that occurs naturally in the environment
Charged particles and energy that are emitted from the nuclei of radioisotopes
states that radioactivity is the process in which an unstable atomic nucleus emits charged particles and energy.
What is plasma?
a penetrating ray of energy emitted by an unstable nucleus.
states scientists can synthesize a transuranium element by the artificial transmutation of a lighter element.
state of matter in which atoms have been stripped of their electrons.
unstable nucleus
What is Transmutation?
elements with atomic numbers greater than 92 (uranium).
states scientists can synthesize a transuranium element by the artificial transmutation of a lighter element.
Charged particles and energy that are emitted from the nuclei of radioisotopes
Any atom containing an unstable nucleus is called radioactive isotope.
What is Radioactivity?
Cobalt-60 is a synthetic radioactive isotope of cobalt with a half-life of 5.2713 years. It is produced artificially in nuclear reactors.
the process in which an unstable atomic nucleus emits charged particles and energy.
Charged particles and energy that are emitted from the nuclei of radioisotopes
a process in which the nuclei of two atoms combine to form a larger nucleus.
