I-131 decays with a half-life of 8.02 days with beta minus and gamma emissions.
Induced gamma emission from long-lived excited nuclei of specific nuclear isomers.
Tc-99m decays mainly by gamma emission, slightly less than 88% of the time.
Metastable isomeric transition is the only nuclear decay mode that approaches pure gamma emission.
Thorium-cycle fuels produce hard gamma emissions, which damage electronics, limiting their use in military bomb triggers.
The hard gamma emissions also create a radiological hazard which requires remote handling during reprocessing.
Tc decays by gamma emission, with a half-life: 6.01 hours.
Induced gamma emission is another approach that is currently being researched.
Routine analysis of precipitation for gamma emissions takes about a week from the time the lab receives the sample.
Induced gamma emission is an example of interdisciplinary research bordering on both nuclear physics and quantum electronics.
