Detailed measurements of the increase in electron transmission through dying spores of Aspergillus niger provided action spectra for dehydration with electron energy peaks of 15 keV. According to this, Haskins' work on the killing effect of cathode rays on the same kind of spores, showing the maximum efficiency of killing at 3.5 keV, can be regarded as an action spectrum for destroying a particular substance in the spore. An explanation of the killing is as follows. White X-rays produced at the surface structure of the cell by impinging electrons with 3.5 keV energy, have an intensity maximum at about 2 keV, which corresponds to the absorption energy of phosphorus. H_3PO_4 molecules situated in the DNA chains absorb the X-ray energy and the chains are broken by releasing oxygen atoms. The dehydration of phosphoric acid by an electron beam was observed in order to check this model.
