showers and areas of high contamination (1.¢e,, areas reading on the order -£ Y rfnr). It is anticipated that the bulk of this early Radsafe survey vill ' gonsist of aerial readings extrapolated to the ground for most of the hot islands. at about this time lagoon water samples will be taken in the anchorages near TARE, This information will receive rapid evaluation for use in the re-entry decisions, Lagoom samples in other regions will be acecrplished as. scom as possible, about this tins alr sampling equipment pre- _ viously set up on site T.RE, the CVE and ENTNETOK will be checked for positive imiications, Data received up to this time will be rodused to a formal Radsafe mumary to CJTF SEVEN for his information. ‘This smmary will contain a recommendation relative to the evacuation of ENTKETOK/VJEL. IG or any other populated ialanis as required, li. about H plus 6 hours, damage survey, lagoon water sampling and Radsafe survey results should be available from the Radsafe CENTER, Sased on the above, a recommendation will be made to CJTF SEVEN reference the designation of Rehour (Re-entry hour) amd the designation of the unrestricted land and water areas, This reecmmendation will makes particular reference pertain- - dng to lagoon traffic ana to wiloading of ships at site T.RE and on the feast bdlity of limited or fulletime cecupaney of site TAKE. It is anticipated that, should conditions be favorable for unloading et TARE, TG 7.3 ships, after unloading, should plan to move outside the lagoon for about 48 hours. Tais ia due to the fact that the aireulation and flushing mechanian of SIXT Lagoon is euch that the arrival of contamination at normal anchorages could be delayed for as long as 40 to 4§ hours (cr more). In the event TARE is act habitable, the Racsafe CENTER will operate from pre-prepared positions on Nw if possible, ctherwise from afjcet. 12. In the event that fall-cut on populated islands becomes, or is forecast, to be critical, or trade routes are affected for more than 24 hours, CIMCPACFLT will be advised accordingly at about H plus 6 to H plus 12 hours. Pertinent off-aite date will be passed to the Radsafe CENTER amt decision reached ag to the need for drinking water sampling at populated atolls cutside the danger area, 13. «+ about H plus @ hours the status of the first ani second sample return aircraft will be enecked and released cr delayed contingent upon the status of sample collection ani recovery operations ani the approval of the Scientific Director or CTG 7.1. le at abous H plus 10 hours ancther summary of the Radsafe sutisation will be prepared for CJTF SEVEN, with particular reference to ENTWETOK/UJELUO (or other off-aite atells), 19. Ouring the period d plus 6 to about H plus 18 hours, a check will 16. at H plus 16 hours, CTG 7.4 will be directed to comtuct Flight #3, be made of the weather island fall-cut situation,i.e., during the time cobris could arrive at theese locations.
