Radioactivity?

Question

hello,
i have few questions for you and this is for my thesis (it is not the actual thesis but still very important) and we have to make people aware of radioactivity
so if you answer my questions accurately, i will be more than happy and i will appreciate

Where is radioactivity used today?
Can we avoid radioactivity?
Should we use radioactivity or not?

thank you very much
if you get the answer from websites or somewhere else, please mention it and list the sources :) (that shows awareness as well)

Answer 1

Radioactivity is used in medicine, to kill cancer cells, and to scan people's body functions.

No, you cannot avoid radioactivity. Your own body has readioactive atoms in it, which are constantly exposing you to small doses of radiation. The earth, and its rocks and minerals, are also radioactive.

Should we use radioactivity? I don't understand the question. There has never been any controversy as far as I know, about its uses in medicine. Why shouldn't we?

Answer 2

Radioactivity is used in a lot of places. Smoke detectors have Americium in them. Take yours down and look at the back and there is even a warning about it. They use radiation to "pasturize" products such as beer when heating the product is not an option. They also use radioactive tags for certain medical scans, fuel rods for powerplants and nuclear submarines. They even used uranium to make vaseline glass because of the neat green glow of the glass. At one point they even used radioactive materials in the paint used on "glow-in-the-dark" watches. So as you can see, radioactive materials and radiation are in a lot of places.

Most people are not subjected to radioactive material on a daily basis because of the tight controls on that type of material. Radiation is another subject. We are subjected to radiation from our computer monitors, the sun, cigarettes, etc. and we can't get away from that easily.

I think that we should limit our use of radioactivity but I don't think we can stop using it all together. It's medical uses as a tag such as Tc-99 are too great. I'm not sure if radioactive power plants are a good idea and I don't know if the radioactive material released from the production of refined Uranium and other fuel sources is at an acceptable level. Personally, I wouldn't live next to a nuclear refinery.

Answer 3

i do no longer see the way it is an argument. i've got not got faith that the Earth became created some thousand years in the past, yet I comprehend that the 0.5-existence of uranium-235 is a computed value, no longer something that has easily been reported by way of fact people have not had the skill to degree radioactivity for that long. So, regardless of volume of uranium-235 that presently exists could, in concept, decay in 704 million years. this does not say something approximately how the present uranium-235 got here to exist or while. in case you may clarify away fossils, radioactive isotopes are a cinch to push aside.

Answer 4

We use radioactivity all the time right now. its used to make electricity (something like 14% of US electricity) and in medicine.

you cannot avoid it. you get more radiation from the sun and naturally occuring Radon then people working at nuclear power plants get a year from the reactor. Heck, you injest radioactivity when you eat a banana (Potassium)

We should avoid using it excessively but not altogether. its a natural and plentiful energy source which has almost zero emmisions and is controlled by US vice foreign powers.

Answer 5

It is used in industrial radiographic testing ( a very valubale Non-Destructive Testing method) - for example, testing of the pipeline welds etc. It is also used in medical diagnosis (thyroid disorders, PET scans etc.) and in the treatment of cancer. It is also used in carbon dating of fossils, determining the age of rocks etc. It is used in food preservation, sterilisation of medical equipment, sludge treatment etc.

We cannot avoid radioactivity because even if man-made radioactivity is completely removed, we will have natural radioactivity from the uranium and thorium deposits, radon which is a radioactive decay product and is itself radioactive, cosmic rays etc.

We should use radioactivity with good understanding and control.

Answer 6

1. cancer research and treatment
2. you can avoid large doses but it permeates everything in small amounts
3. in energy production and science, yes. otherwise, no.

Answer 7

it is used for diagnosis for medical problems like heart mapping, in agriculture, in animal husbandry etc.
