Item A survey of the physics and biological action of cosmic rays with special reference to the effects of secondary cosmic ray showers upon chick embryos(1952) Walker, Leon Bryan; Sawin, H. J.; Huggins, Sara E.; Cominsky, N. CatherineA review of the incedents which led to the discovery of cosmic rays is presented. The corpuscular nature of the readiation is discussed breifly, and the two major components are reviewed with special emphasis being placed upon the soft component. Secondary shower radiation and the frequency of those showers are reviewed. The biological action of cosmic radiation is summarized briefly, and some of the basic research with bacteria, plants and plant seeds, and animals is reported. A report of an investigation into the effects of secondary cosmic ray showers upon chick embryos is included.
