Picture taken at the official opening of the new radiotherapy department in 1954. Each radiation machine is set up in a separate treatment room on both sides of the central hallway.The control desks are situated in the hallway. 




In 1954 the equipment for radiotherapy consists of a Philips type TU 1 X-ray machine for rotation therapy, a Siemens "Konvergenz" converging X-ray machine, a Philips 250kV/25mA stationary X-ray machine, a Philips 50 kV unit for contact therapy, a General Electric Maximar-100 and a Philips Endotherapy 100 kV machine. A Philips universal dosimeter was ordered for the measurement of the dose rate in body cavities. On the TU 1 unit experimental rotational irradiations are started [41]. Physicist Hubertus Wijcker develops a method to measure doses for the rotational treatment.

The picture shows Henri Lokkerbol with the administrative and financial director A. S. L. Spoor BSc. Dr Lokkerbol is introducing the automatic, central registration system of the treatment settings.  In a central location in the department two recorders print the settings (applied high voltages and current, applied filter, radiation time etc.) of every individual radiation treatment on each of the machines in the department. This central registration system is for the most part designed by H. Lokkerbol in cooperation with the Physics department.

   Across the canal, the Netherlands Cancer Institute has special neighbours. Here, the Amstel Brewery is in production day and night. In particular, those working late, with their windows open in the summer, recall the smell of the hops, the clinking of bottles and the activities on the quay.
