Choose one of the radioisotopes
o I Choose Phosphorus-32 (14 d)
2. Using your book and Internet resources, find five interesting pieces of information on the radioisotope you selected. Suggested pieces of information may include:
a. How is the radioisotope formed in nature (type of decay)?
b. Risks associated with the radioisotope
c. Number of subatomic nucleons present
d. Stability of the radioisotope
e. How this radioisotope is used.
f. Is the radioisotope used as a medical tracer? If yes, for what body part or process? Briefly exp
3. Remember to site your sources in APA style.
Explanation / Answer
a) Phosphorus-32 is an isotope of phosphorus which is radioactive. Phosphorus-32 is found in many organic compounds and biological compounds. It is found in Earth in trace quantities.
b) This decays by emitting a beta particle, the beta particle is a high energy particles and is potentially harmful. Also since the the half-life of phosphorus-32 is small tha mount of beta particle emitted is large so it is a potential risk.
c) Number of subatomic nucleons present
It has 15 protons, 15 electrons and 17 neutrons.
d) The stability of the radioisotope is low and has a half life of 14.29 days it decays by emitting a beta particle.
e. How this radioisotope is used.
Phosphorus-32 has important uses in medicine where it is used as a tracer.
In biochemistry it finds uses in analysing metabolic pathways
In molecular biology it finds uses in tracking a plant's uptake of fertiliser from the roots to the leaves.
f. Is the radioisotope used as a medical tracer? If yes, for what body part or process? Briefly exp
Phosphorus-32 is used as a tracer in identification of malignant tumor positions because cancerous cells accumulate more phosphate than normal cells. Thus since it accumulated more from the signal emitted the location of potentially malignant tumors can be traced from outside the body.
