What is iodine 131
Iodine-131 is a radioactive isotope widely used in medical, scientific research and industrial fields. In recent years, with the development of nuclear energy utilization and medical technology, topics related to iodine 131 have frequently appeared in hot discussions. This article will introduce in detail the characteristics, applications and related hot topics of iodine 131, and display hot topics in the past 10 days through structured data.
Basic properties of iodine 131
Iodine-131 is a radioactive isotope of iodine with a half-life of approximately 8 days. It releases high-energy electrons and gamma rays through beta decay and therefore has important applications in medicine and industry. The following are the main properties of iodine 131:
| Features | Description |
|---|---|
| half life | 8.02 days |
| Decay mode | Beta decay (release of electrons) and gamma rays |
| energy | The average energy of beta particles is 190 keV, and the energy of gamma rays is 364 keV. |
| Purpose | Medical (thyroid disease treatment), industry (tracers), scientific research |
Medical applications of iodine 131
Iodine 131 is mainly used in the medical field for the diagnosis and treatment of thyroid diseases. The following are its specific applications:
| Application areas | Specific use |
|---|---|
| Hyperthyroidism | Reduce thyroid hormone production by destroying overactive thyroid cells |
| Thyroid cancer treatment | For removal of residual thyroid tissue and treatment of metastases after surgery |
| Diagnosis | As a tracer, used in thyroid scans and functional assessments |
