Man-made radioactive isotopes find practical application in fields such as________________?
Show answer Hide answer
Answer: E. medical field
Explanation
Man-made radioactive isotopes are produced in nuclear reactors for diverse practical applications. The medical field utilizes these radioisotopes extensively for diagnostic imaging procedures. Radiation therapy also employs man-made isotopes to target and destroy malignant cancer tissues. Radioactive isotopes emit ionizing radiation as their unstable atomic nuclei undergo radioactive decay. Cyclotrons and nuclear reactors bombard target materials with neutrons to synthesize artificial radioisotopes. Medical physics applies radioactive tracers to monitor metabolic pathways within the human body.
Radiopharmaceuticals are administered daily in hospitals worldwide for cancer diagnosis and treatment. Industrial radiography uses man-made isotopes to inspect welds and structural integrity non-destructively. Agricultural research uses radioactive tracers to study plant nutrient uptake and fertilizer efficiency. Power generation relies on natural fissile isotopes like uranium rather than medical radioisotopes. Nuclear fission and fusion refer to fundamental energy generation reactions rather than isotope applications. Nucleonic devices represent instruments utilizing radiation rather than the primary application field itself.
