Believes this changed attitude may have resulted from the fear of public embarrassment if a man who wanted to receive the Nobel Prize was not permitted to travel to Sweden to do so. Not aware of any measures that have been taken to ameliorate passport difficulties.

Dear Dr. Rack:
I am pleased to find your letter of 14 January awaiting me on my return to the laboratory. My wife and I had spent more than three months on our trip around the world. It was a great experience. We visited Sweden, Norway, Israel, India, Thailand, and Japan.
Thank you for your congratulations about the Nobel Prize. The ceremonies in Stockholm were very impressive.
I am sorry that you did not get from Karlsrueh to Heidelberg in time for us to see you in 1953.
The work on abnormal hemoglobins is going along very well. Dr. Murayama here has studied the combination constants with alkyl isocyanides, with, however, rather uninteresting results, inasmuch as the combination constants are not very much different. I had a letter from Harvey Itano in which he said that six more abnormal hemoglobins have now been discovered, making a total of seven, and I suppose that we must assume that still more will be found in the near future.
Let me know what your plans are, when you have made some definite decisions.
With best regards, I am
- Letter from LP to Professor B. Kameswara Sarma, W.G.B. College, RE: Informs him that the competition for graduate assistantships is very keen. Generally assigned to applicants who have had experience in American universities. Recommends that Sarma obtain a Ph.D. in an Indian university, and then consider doing post-doctoral work at Caltech or another American university.

I see that you and I have been put in the position of apparently being on opposite sides in an argument, in the article in U.S. News and World Report of 25 March 1955.
You are quoted as saying "The world is radioactive. It always has been and always will be. Its natural radioactivities evidently are not dangerous and we can conclude from this fact that contamination from atomic bombs, small in magnitude or even of the same order of magnitude as these natural radiations, is not likely to be at all dangerous."
Perhaps it is not justified to say that the natural radiations evidently are not dangerous. In his paper on the genetic effects of high energy radiation of human populations Professor A. H. Sturtevant, who is one of the most able and experienced geneticists in the world, writes that "In particular, there is evidence that irradiation does increase the incidence of leukemia and other malignant growths." Some biologists, at any rate, think that at least some kinds of cancer are produced by somatic mutations induced by naturally radioactive potassium, carbon, and perhaps other elements, as well as by cosmic rays. If this is so, there is little doubt that artificial radioactive substances introduced into the body would also produce these malignancies.
Herman Muller in his 1950 article in The American Scientist, Kurt Stern in Science of 31 December 1954, and Sturtevant all point out that these radiations without doubt produce harmful mutations. In general these mutations are recessive, so that their most seriously harmful effects do not show up in the first generation.
Do you have an argument to show that there is no danger that these effects are occurring?
I note that U.S. News and World Report states that radiation exposure to each individual from all tests to date averages no greater than that produced by one chest x-ray. The point here is that everybody in the world receives this exposure, whereas only a few people are given chest x-rays. Moreover, the geneticists are disturbed about chest x-rays Sturtevant says "In general, the conclusion seems warranted that the
medical 'use of x-rays is dangerous, and should be applied with caution and with full realization of the genetic hazards involved."
I shall be interested to read what you feel about my remarks in this letter.
Ava Helen and I are safely back in Pasadena, after some great experiences during our trip around the world.
With best regards, I am
