(a) (b) Surface fallout studies from JIF 7 data. (1) Initial surveys by TG 4 monitor. (2) Surveys by Scoville and Co. on 8 to 11 March. (3) Survey by P. Schiavone on 25 March. Environmental sampling data on various materials. (1) Soil and H,0 samples collected by Scoville party and sent to NYOO, (2) Animals (pigs, chickens, cats) collected for and sent to NRDL. (3) Marine and other samples collected by Donaldson, etc., during 25 March survey activities. (c) Urine specimens from natives themselves. oa Collected on 14 to 19 March by LASL. 2. Information needed soon (up to rainy season - starting in June to July). (a) Climatological pattern. ~ Present conditions are the last half of the typical dry season which prevails from November to June or July. (b) The rate of change of the environmental contamination during the ° remainder of the dry season is extremely important for early prediction purposes. 3. Information needed during rainy season — during this season most of the translocation and decontamination may be realized. (a) Decontamination - general distributed level of contamination should decrease. (b) Translocation - increased mobilization of contamination and increased growth rates of flora may cause an increase in contamination levels of potential food supplies. 4. | CPIED/DOE .
