Abstract

Two contrasts between medical work with X-rays and with radium highlighted previously would fade during World War I and in the early 1920s. Under pressure from physicists, X-ray clinics would begin to use ionization measurements, thus closing the gap between clinical measurements of X-rays and radium. Prompted by public concern and the reaction of insurance companies as well as workmen’s compensation schemes, radium protection would grow in importance after the War and would become, like X-ray protection, the subject of special studies and recommendations at the national level in France, Britain, and the United States but not in Germany, where there was less sign of public concern. By contrast, the pattern of international cooperation would remain the same. Individual scientists and physicians read the literature published in other countries, often knew their colleagues, and sometimes reacted to work published abroad. Likewise, the various national and local professional organizations concerned with X-rays and radium followed the others’ proceedings and sometimes reacted with similar efforts on dosimetry and protection. But there were still no international norms on these issues, which remained defiantly complex and difficult even as the use of X-rays and radium expanded dramatically.

    For the President’s appeal, see Levy-Dorn’s opening address to the Society’s congress, Verh Deut Rönt Ges. 1914;10, at 16, and for the creation of the Commission see the business meeting, at 18: “Der Zweck dieser Kommission soll sein, die Dosimeter, die landläufig sind und sich irgendwie bewährt haben, untereinander zu vergleichen, damit so feste Daten bekannt werden, auf die Sie sich einigermassen verlassen können; denn wie Sie ja wissen, geben die verschiedenen Dosimeter ganz verschiedene Auskünfte.” Of the sixteen original members, seven are readily identifiable as physicians (including Christen), five as nonphysicians and the remaining four are not readily classifiable.

    For the decision to continue the work of the ·commission, see the II. Rundschreiben des Vorsitzenden. Fortschr Röntgenstr. 1915;23:72: “Es wäre recht erfreulich, wenn die Dosimeter­kommission nach dem Kriege mit den erreichbaren Resultaten hervortreten würde, die wir Daheimgebliebenen unter dem Schutze unserer mächtigen Heeresorganisation fast wie im Frieden leisten könnten.”

  5. 5.

    Fortschr Röntgenstr. 1915;23, at 213: “Der einfache Vergleich der Dosimeter ist von den meisten Arbeitern ausdrücklich oder implizite als unlösbar bezeichnet worden und es hat sich die Notwendigkeit ergeben, zuerst irgendein exaktes Verfahren der Messung der Röntgenstrahlen zu schaffen, und wäre es eine noch so komplizierte Laboratoriumanordnung ….Dazu sollte alles, was Physik und Mathematik geleistet haben und leisten können, herangezogen werden.” Holzknecht’s biography is at Radiation Oncology Institute, Radiological Oncologists: The Unfolding of a Medical Specialty [Internet].

    The British “Measurement” or “Dosimetry” Committee was formed late in 1913, see the Annual Report. Journal of the Röntgen Society. 1914;10:88–97 and reported inconclusively in 1915, see the “Interim Report on the Standardisation of X-ray Dosage,” Interim Report on the Standardisation of X-ray Dosage. Journal of the Röntgen Society. 11:102–10, authorized to be printed in full by the Council at its meeting held on 1 June 1915. The Committee had ten members when it reported, of whom seven were nonphysicians, two were practicing physicians and one was a retired physician. For the French conclusion, see Ledoux-Lebard R, Dauvillier A. Principes rationnels de dosimétrie radiologique. Considération théoriques et pratiques. Journal of Radiology and Electrology. 1916;2:153–62, at 153: “…il est impossible d'arriver à une solution satisfaisante du problème du dosage des rayons X parce qu'il se présente sous une forme beaucoup trop complexe pour que soient réalisables des appareil s de mesure donnant des indications précises et toujours comparables à elles-mêmes.”

    For experiments that indicated that the Kienböck strips and the Sabouraud-Noiré pastilles gave parallel results over a wide range of hardnesses, thus demonstrating that Grossmann’s “theoretical” considerations were incorrect, see Meyer H. Fortschr Röntgenstr. 1915;23:75–6. It was later recognized that these experiments merely demonstrated that the strips and the pastilles were equally insensitive to changes in X-ray dosage.

This report to the Vice-Chancellor ·was communicated to the Senate, which on 17 June 1919 promulgated detailed plans for the syllabus of subjects to be covered by the examination, see the account in The Work of the British Association of Radiology and Physiotherapy. Archives of Radiology and Electrotherapy. 24:209–16. In the first of these reports, it is noted that a physician had contributed £1000 to cover the University’s initial expenses in setting the examination, which would eventually become self-supporting from fees charged the candidates. The examination was given for the first time in July 1920, and the physicians were relieved that “no question on higher mathematics was asked, and a knowledge of only simple calculations would be required…,” see The Diploma in Medical Radiology and Electrology.

The British Journal of Radiology. 1932 Jan 14 and 1931 Nov 19;2:215–233, at 218: “In the spring of 1921 radiology was very near to what might have been a terrific onslaught by the Press. On my way home from a Memorial Service for our old friend Ironside Bruce, whose untimely death caused much concern, I discussed with the Secretary to the Medical Society of London the many references that had been made in the public Press to his death. To my amazement, he informed me that he had been discussing the matter with a member of one of our most powerful papers, and that they had every intention of launching into a warning to the public against the dangers of X rays. I found on enquiry at the office of the paper that my information was correct.” See also, Kaye GWC. Röntgenology: Its Early History, Some Basic Physical Principles and the Protective Measures.

Röntgenschädigungen als Unfälle und Gewerbekrankheiten. Fortschr Röntgenstr. 1924;32:641–7. For the concern with being classified among the “industries insalubres,” see A. Broca, note 59, at 654.

    For the first recommendations of the British X-ray and Radium Protection Committee, dated June 1921, see Journal of the Röntgen Society. 1921 Jul;17:100–3. For the report of the French commission, see Broca, note 59. The British committee had ten members, including the chairman and honorary secretaries, of whom only three appear to have been nonphysicians (two physicists and one X-ray tube manufacturer). The French committee had five members, all presumably physicians since it was appointed by the Academy of Medicine.

    See the report, note 65, at 100: “The danger of over exposure to X-rays and radium can be avoided by the provision of efficient protection and suitable working conditions…”

    Broca, note 59, at 654: “…il y a, comme partout, un seuil. Nous sommes certains de l'existence de ce seuil, car il y a souvent, peut-être toujours, de l'émanation dans l'air que nous respirons, en particulier au voisinage de certaines sources minérales, et ces contrées sont habitées par des populations florissantes; beaucoup de malades même y vont rétablir leur santé.”

    Ibid., at 657: “Il y a certainement un seuil d'action pour les radiations pénétrantes, comme pour toutes les formes d'énergie, et cette vue de l'esprit est confirmée par le fait que nous vivons constamment dans une radiation pénétrante très faible…”

  71. 71.

    Ibid., at 659: “Il n'y a pas lieu, en effet, pour assurer la protection, de réaliser la suppression complète des radiations pénétrantes; il suffit de les amener au-dessous du seuil d'action nocive, et cela est aisé.”

    see American Journal of Roentgenology, 8 (1921) 204, and for its report on electrical dangers, delayed by the death of its chairman, see “Report of the Safety Committee,” presented at the Los Angeles meeting of the American Röntgen Ray Society, American Journal of Roentgenology, 10 (1923) 246–47. I have been unable to find the Safety Committee’s first report (1923) on X-ray protection, but for a follow-up report see Report of the Safety Committee of the American Röntgen Ray Society presented at the 25th Annual Meeting of the American Röntgen Ray Society, Swampscott, Massachusetts. American Journal of Roentgenology. 1924 Sep 3;12:566–71. All of the members are mistakenly identified there as M. D.’s, but at least two (William D. Coolidge and William Duane) were physicists and not physicians.
