Uses (Licensed)
Radioactive sources can be useful when handled under proper professional control and regulation.
The phrase licensed use means radioactive materials are used by trained personnel under appropriate safety rules and legal requirements.
Medical Uses
Radioactive materials can be used for:
diagnostic tracers; medical imaging; * some cancer treatments.
Industrial Uses
Applications include:
checking material thickness; detecting leaks using tracers; inspecting structures; monitoring industrial processes.
Sterilisation
Ionising radiation can be used to sterilise some medical equipment by damaging microorganisms.
Choosing an Isotope
A useful isotope should have properties appropriate to the task, such as:
suitable half-life; suitable radiation type; detectable radiation; manageable exposure risk.
Safety
Radioactive materials should be handled only by properly trained and authorized personnel.
