...world's generals and statesmen, the radioactive "fallout" from nuclear explosions is a grave worry for the future. For scientists who date ancient objects by Carbon 14. it is already a serious nuisance and threatens to get worse. Southwestern laboratories near the Nevada atom-bomb testing ground have found it impossible to use Carbon 14; there is too much competing radioactivity in their vicinity. Even on the Eastern seaboard, Carbon 14 work at the University of Pennsylvania has often been stopped by a radioactive cloud drifting slowly overhead. The "background radiation" gets so strong that the voice of Carbon...
...down when written records are scarce or nonexistent. To find and interpret remains of people who never dreamed of writing, modern diggers have borrowed techniques from many other sciences. They study airplane photographs for soil disturbance. They analyze their finds chemically and date them by their content of radioactive Carbon...
...seven months the labor situation at the Government's vital Oak Ridge and Paducah atomic-energy plants had been as explosive as an Abomb. The C.I.O.'s Gas, Coke & Chemical Workers union wanted a raise in pay, angrily threatened a crippling strike to get it; Union Carbide & Carbon Corp., which runs the plants, turned down the demands. After a three-day strike last July, Labor Secretary James Mitchell and C.I.O. President Walter Reuther both pleaded for a settlement, but negotiations bogged down again; an 80-day injunction only postponed the inevitable showdown...
Steel Doldrums. Amid the general rejoicing, there were some groans of dismay. Alcoa was off 11.4%, to $11,525,459. In the chemical industry, American Cyanamid's earnings went up 14%, to $6,434,475, but Union Carbide and Carbon's net slid to $21,342,676, down 19.3%, and Allied Chemical...
...fastest-changing component, says Dr. Aebersold, is water. It forms about 70% of the body, and about half the water molecules are replaced every eight days. Other fleeting elements are carbon, sodium and potassium. The calcium and phosphorus in bones and teeth stay put longer, but even they are not permanent. "Bones are quite dynamic." says Dr. Aebersold. The little crystals in bones are continually dissolving and reforming. In the process, some of the atoms are lost...
