Half Lives is an enjoyable journey into the odd areas where science and consumerism meet, telling the tale of the entrepreneurs and consumers in radium's history who have until now been considered quacks, or fools, or both.

The discovery of radium in the late 19th century prompted a flurry of experiments to scope the limits of its potential applications. Half Lives tells the fascinating, curious, sometimes macabre story of the element through its ascendance as a desirable item – a present for a queen, a prize in a treasure hunt, a glow-in-the-dark dance costume, a boon to the housewife, and an ingredient in a startling host of consumer products – to its role as a cure-all in everyday 20th-century life.
Finally, it details the gradual downfall and discredit of the radium industry through the eyes of the people who bought, sold and eventually came to fear it.
