technology_Hammer_dosimeter_detector_unit_012
detector unit of ‘Hammer Dosemeter’ - first X-ray therapy dosemeter based on an electrostatic relay
- the detector unit apparently contains also Ra-226 source - our guess is that it was used to reset the X-ray dosimeter by "removing" the electrostatic charge from the electrostatic relay so you can start a new measurement... - measurements with Georadis RT-30N
manufactured by Physikalisch-Technische Werkstätten, or according to the box made in Hamburg by C. H. F. Müller (1920-1949)
