Radiochemistry

Radiochemistry deals with the study of the decay of unstable nudei (radionuclide) and products (particie or radiation) of the decay.

It studies unstable nuclei (radioactive nuclei) which spontaneously emit or stable nuclei from which emission can be induced through different mechanisms.

Each type of unstable nucleus has a characteristic ratę (from fraction of s to billions of years) of radioactive decay.

Density of nucleus = 10¹⁴g/mL

Quahtative analysis: Energy of the emitted particle/radiation is measured Ouantitative analysis: Magnitude of the emission is measured Radioisotope. An isotope of an element that emits a particie or EMR

Radionuclide: A nucleus that emits.

Radioactive: A substance which spontaneously emit radiation or particie or which undergoes fission.

Fissiorr. The process by which a radionuclide decays into at least two pieces which have atomie number greater than 2
