Radioactive isotopes that emit ionising radiation are used in hospitals.
State and explain two safety precautions necessary for hospital staff who work with these radioactive materials.
Explain two reasons why alpha-emitters are not suitable to be used as radioactive tracers injected into a patient's body.
Phosphorus-32 is a radioactive isotope of phosphorus (P\text{P}P) with a proton number of 15 and a nucleon number of 32. It decays by emitting a beta-particle to form an isotope of sulfur (S\text{S}S).
Use nuclide notation to write down the nuclide equation for this decay.
