The isodoses for the ultrahard x radiation of the 15.5Mev betatron in the "side elevated" bodylike water phantom were measured by means of an ionization chamber with the pendulum angle 90, 60, and 30 degrees, and a pendulum axis depth 5, 10, and 15 cm, and the results were compared on the "lying" phantom. The isodoses were set down and discussed, the dependence of the dosage maximum of the pendulum axis depth was plotted in curves, and the valid factors for these trial conditions for the three pendulum angles to measure the tumor dose communicated. Here also the dose on the tumor from the x-ray value, filter, and depth dose factor can be ascertained in a relatively simple way. (auth)
