Balonium

I assumed starship fuel (antimatter or balonium) could be produced from electricity with perfect conversion, so it cost exactly what electricity did — good enough for the one-digit-or-so accuracy needed.

Suppose that we have a Geiger counter and we are able to make measurements, during a ten hour period, of the balonium sample.

The data in Table 7.7 were taken for the highly radioactive element balonium-245.
