Detectors in Medicine and Biology

The invention by Crookes at the end of the nineteenth century of a device called spinthariscope, which made use of the scintillating properties of Lead Sulfide allowed Rutherford to count α particles in an experiment, opening the way towards modern dosimetry. When at the same time Wilhelm C. Roentgen, also using a similar device, was able to record the first X-ray picture of his wife’s hand 2 weeks only after the X-ray discovery, he initiated the first and fastest technology transfer between particle physics and medical imaging and the beginning of a long and common history.
