Questions for direct examination of Dr. Hernar Schluadt: 1. Are you familiar with radioactive measurements? 2. Explain to the Court what you mean by radioactive measurements? 3. What is the difference between Enanation and gamma ray measurements? 4. Have you made both types of measurements? 5. Are you familiar with expired air method of making redioactive deterninations as practiced by Mrs. Hughes? 6. How sensitive do you consider these determinations? 7. In other words what quantity of radium would be necessary in the body to produce an appreciable count by this method? 8. Have you examined plaintiffs by th S method? 9. Have you examined data submitted by Mrs. Hughes? 10. Do you consider that this data is conclusive evidence that there is radio- active materials present in the patients exemined? 11. Explain to the court the essential factors involved in the definite conclus- ions that there might be radon in the expired air? 12. Have you made gamma ray determinations of the complainants? 13. Did you find the complainants radioactive? 14. What do you consider the sensitiveness of the gamma PAY method such as you employed? 15. Do you consider this method as sensitive as the method which Mrs. Hughes claims she employed? 16. Explain to the Court carefully how sensitive you consider the gamma ray instrument which you used to be? 17. Did you not hear Dr. Martland state that with the Wulf instrument which he used for his determinations he was able to detect 1/1000 of a microgram of radium el? 18. Are you familiar with the type of instrument which Dr. Martland used? 19. Do you believe this instrument to be sensitive to such a degree? 20. Are you familiar with the literature on the subject of radium? 21. Are you familiar with the literature on radium involving any hazards? 22. Are you aware that there has occurred in the literature information pointing out the hazards of handling radium compounds? 23. Are you familiar with the medical phase of the literature pretaining to radium? 24. Will you explain to the Court the general nature of the nazards involved? 25. Is it not a fact that such literature refers to comparatively large quantities of radium where deep gamma ray exposure is involved, and not to radium exposure from within the body, that is where radio-active compounds might be deposited in the bone or other organs?
