1. Y EAR 10 S CIENCE ASSESSMENT -3 Diandra Pedavoli Mr. Ingpen

2. Symbol: Co Atomic number: 26 Mass number: 58.933195 Transition metal Cobalt-60

3. D ESCRIPTION OF THE TYPE OF RADIATION IT PRODUCES ? Produces Gamma Radiation Emits two gamma rays of different energies. Gamma rays- electromagnetic released by the nucleus of radionuclides. Gamma photons occur after radioactive decay.

4. E XPLANATION ON HOW COBALT -60 IS USED IN MEDICINE OR INDUSTRY ? Used in Industry Levelling devices Detection of explosives Structural damage

5. D ESCRIPTION OF THE BENEFITS OF USING COBALT -60? Beneficial towards human- Vitamin B12 Used on pregnant women- Red blood cells Beneficial towards animals Ends up in soils and sediments Animals lack cobalt but when in soils and sediments animals get cobalt which is good for their health.

6. D ESCRIPTION OF THE PROBLEMS OF USING COBALT -60? Creates two different problems Health: When breathing it in it effects our lungs and experience symptoms such as; asthma and pneumonia. High concentrations of cobalt-60 lead to; Thyroid damage Heart problems Vision problems Vomiting Nausea Radiation of cobalt-60 can also cause effects.

7. Environmental: Occurs naturally in the environment. We add cobalt to the air little at a time. Cannot be destroyed once it has entered the atmosphere. Activate in acid conditions but most of it ends up in soils and sediments. D ESCRIPTION OF THE PROBLEMS OF USING COBALT -60?

8. J USTIFICATION FOR THIS USE : HOW DO THE BENEFITS OF USING COBALT -60 OUTWEIGH THE PROBLEM ASSOCIATED ? Essential element for pregnant women Beneficial towards animals Used for a wide range of things (industry) Explosives, animals, pregnant women, detecting structural damage to metal parts.
