...biggest plant, Tennessee Eastman, a majority of the workmen voted for no union at all. At the smallest, Monsanto Chemical Co., the A.F.L. came out on top. At the Carbide & Carbon Chemicals factory, where the C.I.O. had trailed the A.F.L. in the first election, it now won by a molecule (25 votes out of 3,811 cast...
...C.I.O. got the hardest blow to the mazard. At the big Tennessee Eastman Corporation the C.I.O. was out of the race altogether; there the run-off decision would be between no-union and the second-place A.F.L. At Carbide & Carbon and Monsanto Chemical, C.I.O. got snowed under by the A.F.L., but will have a second chance to fight it out again...
...almost invisible speck of radioactive carbon-a millicurie*- became the first byproduct of atom-bomb-making to be released for medical research. Last week's buyer (at $367 plus handling charges and deposit on the bottle): the Barnard Skin and Cancer Hospital of St. Louis, which will use it only in research. It will not cure cancer...
Radioactive carbon is not new; "C-14" has been made in cyclotrons for seven years but in even more minute quantities and at far greater cost. Other elements can also be made radioactive, but C14 is the most useful for cancer research because 1) it remains radioactive for thousands of years, can be recovered and used again, 2) carbon is the key element in all body chemistry. Barnard's researchers will use it as a tracer (it signals its presence by shooting off radiation) to study the metabolism of cancerous cells which must be understood before the disease...
...typical pile is a 20-foot block of graphite (pure carbon) interlarded with lumps of fissionable uranium. The chain begins with the capture of a neutron by a uranium atom. When the atom "fishes" (splits by fission), neutrons released by the reaction fly off at more than 6,000 miles a second. To give the neutrons a maximum chance of being captured by other uranium atoms, they are slowed to "thermal" speed-roughly 3 m.p.s. Normally a neutron slows down to that speed after about 110 collisions with carbon atoms...
