%X The relationship between incident intensity of X-rays and the ionization produced by them in a small cavity behind an aluminium wall of given thickness has been derived, and calculations performed for a specific case. The conditions of validity of Gray's relation are the only ones imposed. The calculation was performed for monoenergetic radiation, and extended to the case of a bremsstrahlung spectrum of the form given by Schiff (Adams 1948). Comparison is made with the work of Fowler, Lauritsen, and Lauritsen (1948) and Lawson (1950).
