noun
- A radioactive isotope of radon (radon-219) produced in the decay series of actinium.
Usage: chemistry; physics; technical term
Examples
- Actinon is a short-lived decay product in the actinium-235 decay chain.
- The presence of actinon in laboratory samples must be carefully monitored due to its radioactivity.
- Actinon decays rapidly into francium-215 with a half-life of about 3.9 seconds.
- Scientists studying actinium decay series often track actinon as an intermediate product.
