The significance of the total and primary degraded electron spectra is discussed, and the application of the theory developed by Fano and Spencer to the calculation of total electron spectra is illustrated for irradlition of water by the followlng x-ray doses: 130 kvcp, 3 mm Al hvl; 200 kvcp, 0.5 mm Cu hvl; 250 kvcp, 1 mm Cu hvl; 230 kvcp, 2mm Cu hvl; 1 Mevp, 3.4 mn Pb hvl; Co/sup 60/ gamma rays; 25 Mevp betatron x rays. The significance of absorbed dose is discussed. The absorbed dose relative to the roentgen (D/r) and to cavity ionization (D/J) with absorbing materials of water, Lucite, and polystyrene is calculated and tabulated. The linear energy transfer (LET) distributions produced by the continuous electron spectra are shown graphically. (auth)
