Question 32
a.

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.

[4]
b.

Explain two reasons why alpha-emitters are not suitable to be used as radioactive tracers injected into a patient's body.

[2]
c.

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.
