what are the risks and benefits associated with radioisotopes?

effects: hair loss, skin burns, nausea, gastrointestinal distress, or death (Acute Radiation Syndrome). Long-term health risks include an increased cancer risk. Such risks depend upon the function of the specific radioisotope; and the route, magnitude, and duration of exposure.

All the artificial elements are radioactive. 'Artificial Radioactivity' is the branch in nuclear science that deals with the production of artificial radioisotopes that find applications in diverse fields such as basic sciences, healthcare and industry.

Radiation exposure is a proven risk factor for thyroid cancer. Sources of such radiation include certain medical treatments and radiation fallout from power plant accidents or nuclear weapons. Having had head or neck radiation treatments in childhood is a risk factor for thyroid cancer.

The PET scan involves radioactive tracers, but the exposure to harmful radiation is minimal. According to the Mayo Clinic, the amount of radiation in the tracer is small, so the risks to your body are low. Still, it's a good idea to discuss possible risks with your doctor.

There are no known long-term adverse effects from such low-dose exposure. Some potential side effects that might occur include: Bleeding, soreness or swelling may develop at the injection site and allergic reactions to the radiopharmaceutical may occur, but are extremely rare.

The dose of radioactivity you will receive is very small (for most Nuclear Medicine tests usually in the range of the dose you receive from a chest X-ray) and will not cause any problems.

The risk of harm from this amount of radiation exposure is low, and the benefits outweigh the risk. Furthermore, there has never been a case of breast cancer proven to be caused from radiation exposure during a mammogram.

Exposure to large amounts of radioactivity can cause nausea, vomiting, hair loss, diarrhea, hemorrhage, destruction of the intestinal lining, central nervous system damage, and death. It also causes DNA damage and raises the risk of cancer, particularly in young children and fetuses.

When used in medical practices, radioisotopes are used particularly for diagnosis and therapy of various medical conditions. In regards to diagnoses, the isotopes are used in conjunction with scanning machines such as MRI, CT scans, and others, to image and diagnose disorders that couldn't otherwise be seen.

Because uranium is a radioactive substance health effects have been researched. Scientists have detected no harmful radiation effects of natural levels of uranium. However, chemical effects may occur after the uptake of large amounts of uranium and these can cause health effects such as kidney disease.

Keep people away from it to reduce their exposure to radiation. Keep cuts and abrasions covered when handling contaminated items to avoid getting radioactive material in them. Wash all of the exposed parts of your body using lots of soap and lukewarm water to remove contamination.
