摘要:

A balance method of measuring absorption coefficients for X-rays in absorbing media, using a new form of sectored discs for determining alterations in intensity and an ionization chamber containing three electrodes, has been developed. The new arrangement makes possible a simplification of the apparatus, a complete elimination of certain sources of error, and very direct calculations of the results. A curve is included in this report to indicate the accuracy routinely attainable.
