Study Notes
Radioactive Isotopes in Medicine
- Radioactive isotopes are used as diagnostic tools in medicine
- Cells use radioactive atoms in the same way as nonradioactive isotopes of the same element
- Radioactive isotopes are incorporated into biologically active molecules to track atoms during metabolism
Diagnosis of Kidney Disorders
- Kidney disorders are diagnosed by injecting small doses of radioactively labeled substances into the blood
- The labeled substances are then analyzed in the urine to track the tracer molecules excreted
- This process allows for the diagnosis of certain kidney disorders
Radioactive Isotopes in Medicine
- Radioactive isotopes are used as diagnostic tools in medicine to track atoms during metabolism.
- Cells use radioactive atoms in the same way as nonradioactive isotopes of the same element.
- Radioactive isotopes are incorporated into biologically active molecules, which are used as tracers.
Diagnosis of Kidney Disorders
- Kidney disorders are diagnosed by injecting small doses of radioactively labeled substances into the blood.
- Tracer molecules excreted in the urine are analyzed to diagnose kidney disorders.
Use of Radioactive Tracers in Cancer Diagnosis
- Radioactive tracers are used in combination with imaging instruments, such as PET scanners.
- PET scanners monitor growth and metabolism of cancers in the body.
Risks of Radioactive Isotopes
- Radiation from decaying isotopes poses a hazard to life by damaging cellular molecules.
- The severity of damage depends on the type and amount of radiation an organism absorbs.
Environmental Threats
- Radioactive fallout from nuclear accidents is one of the most serious environmental threats.
Safety of Medical Diagnosis
- The doses of most isotopes used in medical diagnosis are relatively safe.
