A simple Technique for direct Observation of the Effect of Radiation on living Cells in Vitro

L. G. LAJTHA M.D., D.PHIL.1 and R. OLIVER M.Sc., A.INST.P.1

1 Department of Radiotherapy, Churchill Hospital, Oxford

A chamber with glass coverslip at top and bottom is filled with a beta-emitting radioactive isotope (e.g. P32). A drop of cell-suspension placed on top of the chamber may then be irradiated at dose-rates up to 20,000 rep/hour, while the optical conditions remain unimpaired for microscopical examination. Extra protection for the observer is unnecessary.
