Radioactive isotopes have a variety of applications. Generally, however, they are useful because either we can detect their radioactivity or we can use the energy they release. Radioactive isotopes are effective tracers because their radioactivity is easy to detect. A tracer A substance that can be used to follow the pathway of that substance through a structure.
The Kinetics of Radioactive Decay and Radiometric Dating - Chemistry LibreTexts
Many rocks and organisms contain radioactive isotopes, such as U and C These radioactive isotopes are unstable, decaying over time at a predictable rate. As the isotopes decay, they give off particles from their nucleus and become a different isotope. The parent isotope is the original unstable isotope, and daughter isotopes are the stable product of the decay. Half-life is the amount of time it takes for half of the parent isotopes to decay. The decay occurs on a logarithmic scale. For example, the half-life of C is 5, years.

The digital dating sphere can prove tricky, and bruising, for the trans user. But he, like many people using dating apps whatever their sexual identity, remains stoutly positive. Allegations of transphobia are not new in the world of gay online dating.
