Radioisotopes are isotopes of an element with an unstable nucleus, causing them to emit radiation as they decay into more stable forms.
Applications:
Due to their radiation-emitting properties, radioisotopes are utilized in various fields:
1) Medical Imaging and Treatment:
Technetium-99m, Iodine-131, and Cobalt-60 are commonly used in diagnostic imaging and cancer treatment.
2) Industrial Applications:
Used for detecting leaks in pipes, measuring material thickness, and sterilizing medical equipment.
3) Research:
Used to trace the movement of atoms in chemical reactions, study proteins and enzymes, and determine the age of rocks and fossils.
4) Environmental Monitoring:
Monitor environmental pollution, such as radioactive releases from nuclear power plants.
Importance of Studying Radioisotopes
The study of radioisotopes is crucial across many fields.
It enables the detection, measurement, and monitoring of radiation, leading to numerous practical applications in medicine, industry, research, and environmental monitoring.
Study of Sodium Iodide I-131
The study of radioisotopes like Sodium iodide I-131 involves using various techniques to measure the radiation they emit.
Sodium iodide I-131 is a radioactive isotope of iodine that emits beta particles during its decay process.
