146 THE SHORTER-TERM BIOLOGICAL HAZARDS OF A FALLOUY FIELD protect against the radiation. Mavbe it would not bea gas mask. This illustrates our difficulty ation it was common practice for the fellows to sleep topside with lite or no clothing on, of working with yourface covered. and if they relied completely on the reading of of this thing, There are lots of things you can do about it. The question in my mind is just slept there through the nigh€ with 70 1 per hour, they would have had quite a nice erythema and would have euded up with ulcers and other difficulties. So IT began then the argument that under certain situations it is Mr. Lainpwarm. 1 wonder about the payoff what the payoff is when you go to the trouble of putting in something like that that might wind up giving you something useless in the long run. Mr. Greens. Let me mention that if one does use an ionization chamber at atmospheric pressure, and it is not putictured, vou can still use it. [ think we better fight this out some other way. “ol Brennan. This is a very interesting angle and the whole point of looking at this. Does anybody have any other comments? Dr. Morcax (CORNT,). I didn’t want to get into this argument, but 1 recall away back in the Bikini days that they threatened to throw meoverboard unless 1 kept my mouth shutand. quit complaining about the beta-gammaratio. Finally they gave me a crew of men and we went out and made measurements and as I indicated before on the topside of MFT ships, we found values as high as several hundred. In onecase it was as high as 700. In sucha situ- the gamma. instruments, say 1 re per hour, and quite vital that we do measure the betagamma ratio or measure the beta dose even though it is a difficult job. We do it in the laboratory under all types of eonditions. [t can be done. I knowthat there are some prob- lems but just because # job is hard to do, I think is no reason why you should run the risk of sacrificing the lives of people. Col. Brennan. J certainly would agree with that. In general, then, the responsive action would be to cither protect against it in lerms of clothing or time or geometry, and be very sure you have good protection or if you can’t do that, you are prettvy much conumitted to measure it. At least measure it often enough to control the hazard, however difficult that may be. That is at least the direction one ought to go. Topic V Internal Emitters
