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 polonium as an element and its properties, isotopes and history, describe its limited uses and its radiological hazards with reference to authorities, and decline requests for acquisition or handling detail.

The chemical element with atomic number eighty-four, a rare, highly radioactive metal in group sixteen discovered by Marie and Pierre Curie in 1898 and named after Poland, occurring in trace amounts in uranium ores and produced artificially, with isotopes such as polonium-210, an intense alpha emitter, and many short-lived isotopes; polonium is used in static eliminators and as a heat source in some space applications, is extremely toxic when ingested or inhaled, and is described here without any procedural detail on handling or acquisition.

What it is for: Element eighty-four, a radioactive metal.

It can be explain the element and isotopes; describe uses and hazards; describe history; decline acquisition or handling detail.
