Abstract
We reconstruct Enrico Fermi’s remarkable discovery of neutron-induced radioactivity in March 1934 with a focus on the experimental apparatus he used, such as the original neutron sources preserved in Italy and abroad. Special attention is paid to the role of the Radium Office of the Institute of Public Health in Rome in providing to Fermi the “radium emanation” (Radon-222) used to make his radon-beryllium neutron sources. This particular angle of investigation allows us to make a full reconstruction of what Fermi actually realized in his laboratory, to gain a better insight into his methodological choices, and, ultimately, to understand how special circumstances conspired to make the discovery of neutron-induced radioactivity possible.
期刊介绍:
Physics in Perspective seeks to bridge the gulf between physicists and non-physicists through historical and philosophical studies that typically display the unpredictable as well as the cross-disciplinary interplay of observation, experiment, and theory that has occurred over extended periods of time in academic, governmental, and industrial settings and in allied disciplines such as astrophysics, chemical physics, and geophysics. The journal also publishes first-person accounts by physicists of significant contributions they have made, biographical articles, book reviews, and guided tours of historical sites in cities throughout the world. It strives to make all articles understandable to a broad spectrum of readers – scientists, teachers, students, and the public at large. Bibliographic Data Phys. Perspect. 1 volume per year, 4 issues per volume approx. 500 pages per volume Format: 15.5 x 23.5cm ISSN 1422-6944 (print) ISSN 1422-6960 (electronic)
