Did u mean natural or artificial Radioactivity..???
Well here are for artificial radioactivity............
there are many uses: -
1. IN MEDICINE
FOR DIAGNOSTICS AS A TRACER: -
a tracer is a minute amount of radio isotope which is mixed with a nonradioactive medium and injected into the vein of the patient.A radiation detecting device like a Geiger Mullar counter is used to locate blood clots or blocks by moving the counter slowly to different parts of the body. For this purpose radio Na at.no. 11 at.mass 24 is used. IODINE atomic no. 53 atomic mass 131(radio iodine) is used as a tracer to determine the activity of the thyroid gland. radio Na is also used to check the functioning of the heart and maintaining blood circulation.
FOR RADIOTHERAPY: -
Radio Iodine is also used in the treatment of defects in the Thyroid gland. Radio Cobalt at.no.27 at.mass 60 is used in the treatment of cancer in place of more expensive Radium.
Radio phosphorous at. no.15 at.mass 32 is used in the study of bone metabolism & for the treatement of blood diseases.
2. IN INDUSTRY: -
Radio isotopes are used
a. in testing and controlling the thickness of paper, metal and rubber sheets.
b. in detecting flaws in the interior of metal castings (radio Na)
c. in detecting wear and tear of machinery
d.in detecting welding defects in pipe lines.
3. IN AGRICULTURE
a. Radio phosphorus is used in fertilisers to study the assimilation of phosphorus by plants, thus leading to the improvement of fertilizers
b. Radiation from radio isotopes are used for developing high variety of rice and wheat
4. IN ANTHROPOLOGY
Radio Carbon at.no.6 at.mass14 is used in estimating the age of the earth, relics, mummies, fossils etc...
PS : -
Radio carbon is also used in the study of protein metabolism and archeological dating.
HOPE THIS HELPS YOU.............

If you are in the states the best bet would be to contact the regulator, the Nuclear Regulatory Commission, they would have statistics on that. In Canada its CNSC, UN = IAEA
(see links below)
Isotopes can be used in densiometers to measure rainfall, test the interior of trees and telephone poles for cracks, test the wall thickness of pipes. In medicine they can be used for tissue irradiation or as a tracer (different chemicals migrate to different organs etc depending on their function, i.e. iodine to thyroid gland).
I'm sure there are many other uses than listed.

The uses are:
Uranium-235, is used as a fuel in nucler reactors.
Cobalt-60, is used in the treatment of cancer.
Iodine-121, is used to treat goitre.
Sodium-24 and Arsenic-74, are used as tracers in the human body.
These are uses in both the industry and medical.
Hope you will rate as the best answer!

Some thyroid disorders can be cured, but many require lifetime treatment. Learn here https://tr.im/eWjGE
For example, sometimes early stage thyroid cancer can be cured by surgery to remove the thyroid gland, but you will need to take thyroid hormone medication afterwards for the rest of your life. Goiters can also be surgically removed and do not always recur after surgery. In most cases, thyroid disorders need treatment over a lifetime. However, with treatment most people with thyroid disorders can live normal, healthy lives.

No, there are no longer any reward. cleansing soap and water guard the penis undemanding- no longer reducing off the foreskin. It does no longer limit STD's- condoms and teaching your son truthful intercourse does. Circumcision truly aspects a male to evaluate much less exhilaration, it dries out the glands and there are a number of themes that could come from the approach. Plus, 85% of the international is UNcircumcised, simplest 30% of u . s . voters at the instant are circumcising- and the numbers are reducing rapid!
