Kinetic theory of matter
KTP States that all matter is composed of particles which have intermolecular space between them, attract each other witch force and are in continuous random motion |
Radioisotopes
Isotopes differ in the number of neutrons resulting in different mass numbers |
Radioactive isotopes are used in nuclear medicine for: |
▶ Diagnostics |
▶ Treatment |
▶ Research |
▶ Tracers |
▶ Geological clocks |
