Marie Curie, now at thehighest pointofherfame and, from 1922, a member of the Academy of Medicine, researched the chemistry of radioactivesubstancesand theirmedicalapplications.
After poring over the data, engineers and physicists noted a recurring pattern 33 days long that affected the decay rates of the various radioactivesubstances.
Japanese military planes were also dispatched to collect air samples above Japan for traces of radioactivesubstances that could have been released as a result of the test.
