CEEETRENTIAL CHAPTER I SUMMARY AND CONCLUSIONS For the purposes of this report, the summary and conclusions are collected here. Detailed calculations and other data utilized in ar- riving at these conclusions may be found in the individual chapters. 1. The Japanese data showed that their highest dose-~rate reading was only fifteen times their background readings as recorded during the early part of their voyage. 2. The relatively low cumulative gamma readings recorded on the SATUMA dosimeter do not necessarily indicate a true dose. It is entirely probable that radiation leakage of the instrument accounted for a large portion of the recorded dose. If accepted as real, it in- dicates a total dose of 50 milliroentgens between the dates July 8-19. 3. The rediation dose rates on both the TAKUYO and SATUMA at the tine of monitoring were found to be substantially identical. The decontamination measures cerried out on the TAKUYO were effective in reducing the radiation level to essentially background. 4. Japanese data maximizes the whole body gamma dose inasmuch as the scintillation probe was held almost in contact with the deck. Similarly our radiation monitoring data is maximized since the geiger probe was also held in this same position. 5. The maximum radiation dose possible to TAKUYO personnel is calculated to be less than 5 milliroentgens. This assumes continu- ous exposure for the 15 hours from start of the rain squall to the end 1 KeereRig esse wes COREeCELE:L r wee pen DOE ARCHIVE
