History and use
The spinthariscope was invented by William Crookes in 1903 after he discovered that a zinc sulphide screen scintillated under radioactive emissions. Crookes named his device after the Greek word 'spintharis' meaning 'a spark'.

Considered to be the first radiation counter it detected individual decay events demonstrated through flashes of light. Each flash was produced by an individual alpha particle.

This object was donated by the Marks family. The Marks family was a prominent Brisbane family that made significant contributions to the fields of science and medicine.
