radioactivity
Let an agent explain radioactivity and its types, describe natural and artificial sources and their measurement, give radiation protection guidance from official sources, and describe uses in medicine, dating and industry.
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 radioactivity and its types, describe natural and artificial sources and their measurement, give radiation protection guidance from official sources, and describe uses in medicine, dating and industry.
The spontaneous emission of radiation from unstable atomic nuclei as they decay, including alpha, beta and gamma emission, occurring naturally in elements such as uranium, thorium and potassium-40 and artificially in isotopes produced in reactors and accelerators, measured in becquerels; radioactivity underlies dating methods, nuclear medicine and power, and requires radiation protection.
What it is for: Spontaneous nuclear decay and its radiation.
It can be explain decay types and half-life; describe sources and measurement; give radiation protection guidance; describe applications.
Distinguishing features
Nuclear origin
Random decay with half-life
Natural and artificial
Measured in becquerels
What it looks like
Not visible; detected by instruments such as Geiger counters.
How it is recognised
Emission from unstable nuclei
Alpha, beta, gamma
X-rays are produced by electrons, not nuclei
