The spectroscopy and dosimetry of silver-L radiation for biophysical applications
Description
In order to carry out biological radiation experiments with low energy electrons, whose limited range as a rule even for single cell layers is not sufficient to pass through the cytoplasm to the nucleus, one must work with low energy X-rays. The electrons which are released directly in the cell by the photo effect are then the biologically active, directly ionized particles, whose starting spectrum can be determined by the selection of the photon spectra. The problem was to build an apparatus for irradiation of thin cell layers with low energy X-rays, which contained a large portion of the silver-L lines at approximately 3 keV, as well as to carry out the necessary spectrometry and dosimetry with the silver anode tubes and to optimize the irradiation parameters.

Um strahlenbiologische Experimente mit niederenergetischen Elektronen ausfuehren zu koennen, deren geringe Reichweite selbst bei monozellulaeren Schichten in der Regel nicht ausreicht, um das Zytoplasma bis zum Zellkern zu durchdringen, arbeitet man mit niederenergetischer Roentgenstrahlung. Die unmittelbar in der Zelle durch den Photoeffekt ausgeloesten Elektronen sind dann die biologisch wirksamen, direkt ionisierenden Teilchen, deren Startspektrum durch Wahl des Photonenspektrums festgelegt werden kann. Aufgabe war es, eine Apparatur zur Bestrahlung duenner Zellschichten mit niederenergetischer Roentgenstrahlung aufzubauen, die einen grossen Anteil der bei etwa 3 keV liegenden Silber-L-Linien enthielt, sowie die notwendige Spektrometrie und Dosimetrie an der verwendeten Silberanodenroehre durchzufuehren und die Bestrahlungsparameter zu optimieren.
