radioactive decay
Let an agent explain radioactive decay by mode, half-life, detection, uses and radiation safety, without facilitating harm.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain radioactive decay by mode, half-life, detection, uses and radiation safety, without facilitating harm.
The spontaneous transformation of an unstable atomic nucleus into a more stable one by emitting radiation, such as alpha, beta or gamma radiation, neutrons or through isomeric transition, at a rate characterised by the half-life.
What it is for: Nuclear physics, dating, medicine and energy.
It can be explain decay modes; calculate half-life and activity; describe uses such as radiocarbon dating; find radiation safety information.
