-18- - 3. Drinking Water Pathway The analysis of the cistern water and ground water have been published in detail in a separate report (4). were performed. Both radiological and chemical analyses A summary of the radiological quality of the water wil} be presented here. For more detail and for data on the chemical quality, _the original report should be consulted. The data from the cistern water in Bikini Island are given in Table 6. The ground water data from Bikini and Eneu are listed in Table 7. For the alternate living patterns it is assumed that only the cistern water will be used for consumption. Therefore, the dose assessment via this pathway was based upon the average values listed in Table 6. The ground water data is presented to give a comparative picture in the event ground water were used for potable water. The 10, 30, 50 and 70 year integral doses resulting from the consumption of Bikini cistern water were listed in Table 8 and are of the order of a few millirem for whole body and bone marrow. the subsequent dose summary tables. contributed almost entirely by '37Cs. These are the doses used in The whole body and liver dose is 3°Sr and 1?7Cs are approximately two orders of magnitude more Significant than 239°2"pu in contributing to bone marrow dose. Table 9 and 10 compare the doses based upon. the consumptions of Bikini and Eneu ground water. The 30, 50, and 70 year doses resulting from consumption of Bikini ground water range from 1 to 2 rem for bone marrow and 0.4 to 0.7 rem for whole body. This is a very Significant increase over the estimates resulting from consumption of cistern water. The estimates based upon consumption of Eneu ground water also (Table 10) exceed those based upon consumption of cistern water; the 30, 50 and 70 year integra] doses range from 0.2 to 0.4 -rem for mee gis;
