They were not, however, kept entirely secret. Long-range atom-bomb watching has become a favorite sport in Japan. When nuclear tests are impending, whether by the U.S. or the U.S.S.R., all sorts of instruments are checked and tuned for superfine sensitivity. This year a survey ship, the Shunkotsu Maru, carrying scientists and scientific apparatus, has been cruising near the danger area in the Pacific, and tuna boats have been gathering radioactive dust. Japanese scientists relish the fact that they are the only ones in the world who make observations and report them openly...

...weeks after these explosions, the Shunkotsu Maru collected very little radioactive material, and Japanese scientists conjectured that the explosions, which took place high in the air, had tossed most of their "hot" residue into the stratosphere in the form of extremely fine dust. The explosion on March 1, 1954 behaved differently because it was a "tower shot" that stirred up millions of tons of quick-settling coral dust. First radioactive material from the May 21 explosion was brought home by the tuna boat Stiruga Maru. Analyzed by Dr. Kenjiro Kimura of Tokyo University, it proved to contain a familiar array...

Slow-Falling Dust. Last week the Shunkotsu Maru reported radioactive dust from a third explosion that apparently took place on June 12 or 13. Analysis showed that it was also of the fission-fusion-fission type, but for some reason, perhaps small size or extremely high altitude, it did not stir up air or water waves strong enough to reach Japan. A small earth wave was detected on June 12, and a slightly stronger one on June...
