Since each megacurie is roughly as potent as 2,200 Ibs. of pure radium, this is a large amount of radioactivity. Mn-54 has a rather long half life, 291 days, and since it is absorbed by living organisms, the Navy's safety men have added it to their list of dangerous fallout isotopes. They are now looking for plants and animals that may pick it up as it floats around the earth, and concentrate it in their tissues. They already know one plant, tea. that is avid for manganese and may concentrate the radioactive kind...
Exhaustive Author Jones counts no fewer than 33 operations (plus endless Xray, radium and diathermy treatments) over the next 16 years. One of the more unusual operations: Freud had himself sterilized (by tying off the major sperm ducts) on the chance that a changed hormone production might retard the growth of the cancer. There is no evidence that it had any such effect...
...most of their calcium from vegetables that were grown in calcium-deficient soil. Such people may come much closer to the "permissible" level. The permissible level itself is still considered debatable. It was derived principally from a small amount of experience with the cancer-causing effects of radium in the bones; at that time no strontium 90 existed in the world. When more is known, the permissible level for strontium 90 may have to be lowered sharply...
Died. Mario Ponzio, 71, cancer researcher and professor of radiology (since 1936) at the University of Turin, who underwent 19 operations to delay his inevitable death from radium burns suffered in his experiments, in 1955 was awarded Italy's highest honor, the Gold Medal for Valor; in Turin, Italy...
Russian papers published in 1939 and 1940, say the Rand team, prove that Soviet nuclear physics was as advanced at the time as in any other country. Its apparatus was plentiful and excellent. The first cyclotron on the European continent was in operation at the Leningrad Radium Institute before 1940. Two other cyclotrons were in the works, one of which (if the war had not intervened) would have been three times more powerful than the 60-inch cyclotron at Berkeley, then the world's biggest...
