The peak radiation the ship encountered averaged 0.008 R/hr (gamma only), with a maximum of 0.035 R/hr (gamma only). The masts above the spray from the washdown system were the area of greatest radioactivity. After these were hosed down and the decks washed down, the radiation levels decreased to an average of 0.003 R/hr with a maximum of 0.02 R/hr. On 6 November, when the ship returned to Enewetak, the radiation intensity had decreased to an average of 0.0004 R/hr, with a maximum of 0.003 R/hr (IPO 132.3243). Mmore Fone ( (pemo fed The USS Radford (DDE-446) and the USS Fletcher (DDE-445) reported , — seg radioactive fallout while at sea off of Enewetak Atoll] between midnigh®=doys and 1200 on 3 November. The fallout was most noticeable during and immediately after rain squalls and averaged 0.001 R/hr, with an occasional maximum approaching 0.003 to 0.004 R/hr (IPO 132.3#1). Regulations required that a ship have a level below 0.0006 R/hr if it was to be given final radiological clearance, so on 5 November TG 132.3's radsafe staff checked all ships and pointed out areas needing further decontamination. By 8 November all ships had radiation readings below the required level. Conclusion of MIKE ¥ The night of 3 November, the Commander of the Joint Task Force sent a final radiological safety advisory to the Commander of the Pacific Fleet stating that fallout from MIKE posed no health hazard to surface or air §-27
