The sensitivity of cells to the lethal action of X-rays

Abstract

This thesis consists of three papers which record an experimental investigation into the nature of the biological action of X-rays. An introduction has been added in order to correlate the papers with each other and to draw attention to the significance of the experiments described in the papers in relation to the records of work by other investigators.Part I. Introduction. • Part II. The Biological Action of Homogeneous and Heterogeneous X-rays. Proc. Roy. Soc. 1933. B.112, 365. • Part III. The Action of X-rays on the Eggs of Calliphora. Proc. Roy. Soc. B. 1934. In press. • Part IV. The influence of temperature on the sensitivity of calliphorine eggs to X-rays. (This paper is about to be submitted to the Royal Society for publication).
