G. SUMMARY AND CONCLUSIONS 1. The Japanese data showed that their highest dose rate reading was only fifteen -imes their background readings as recorded during the early part of their voyage. 2. The background radiation level (0.06-0.07 mr/hr beta-gamma) in Rabaul was substantial, comparatively. No explanation for this is offered. 3. 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, 4 The radiation dose rates on both the TAKUYO and SATUMA at the time of monitoring were found tc be substantially identical. The decon- tamination measures carried out on the TAKUYO were effective in reducing the radiation level to essentially background. 5. Japanese data maximizes the whole body gamma dose inasmuch as the scintillation orobe was held almost in contact with the deck. Simi- larly our radiation monitoring data is maximized since the geiger probe was also held in this same position. 6. The maximum radiation dosepossible to TAXUYO personnel is cal- culated to be less than 5 milliroentgens. This assumes continuous ex- posure for the 15 hours from start of the rain squell to the end of the decontamination, at the highest count rate recorded by the Japanese. The dose rate by our own measurements at the time of our arrival was so small as not to permit any tenable calculations on this basis, Japanese data was used inall calculations. Therefore, the It will be noted that there : DOE ARCHIVES . cparseeri eos fAawie Year: use”. wR ee 3?
