Radioisotope
(noun)
A type of isotope that is unstable and emits radiation.
Origin:
From radio- + isotope.
Examples:
- Radioisotopes are used in medical imaging and cancer treatment.
- The half-life of a radioisotope determines how long it takes for half of its atoms to decay.
- Radioisotopes are produced through the bombardment of stable isotopes with high-energy particles.
- The radiation emitted by radioisotopes can be measured to determine their age or use in industry.
- Radioisotopes are widely used in scientific research, industrial processes, and energy production.
