© oncert”@ Schedule I affords high probability of maintaining a very necessary temporary camp on Oboe until Event No. 11 is ready for firing. The inclusion in Schedule I or Schedule II of shots with yields greater than 5 Mf at Bikini poses the problem, as at Eniwetok, of personnel safety in the atoll. This condition will exist on four events, 12, 13, 14, and 15 in Schedule I but on only one event in Schedule II. It is the opinion here that the firing of the 25-ho mr’ sevice at Bikint in the northern lagoon at Charlie or Fox/George could result Noe in the following damage: (1) Loss of the 300 foot commmications tower on Nan. / (2) Loss of the fireball photo towers on William and How.’ (3) Irreparable damge to Station 1512 and Station 1528 on George plus Station 1321 on Dog if fired at Fox/George. (4) Undesirable, but reparable, damage to Station 1320 on Dog if the shot is fired in the Fox/George region. i. (5) Loss of Station 1319 and Station 1200 on Charlie if the shot is . fired in this region. (6) Demolition of the Han Camp buildings.’ Schedule II affords uninterrupted periods for technical readiness for the first six shots in the Tere island complex. These shots ore small enough to warrant optinism as far as weather delays are concerned and the technical preparatio. period is not affected by simultaneous firing of large yield shots in the northern test areas. The entire period from 1 Mzy to 31 May under Schedule II can be utilized at Bikini for the inclusion of the DOD shots in the schedule with full assurance and reasonable guarantee of being able to conduct this pro- gram in uncontaminated areas as far as the proposed four diagnostic rocket launching sites to be manned during the UHA shots are concerned. This time can be extended to 8 June if one assumes that the possibile fallout interference from Event 12 does not constitute a major delay risk. From the UCRL viewpoint, the concept of operation at Taongi would be conducted in a manner involving an absolute minis of installations ashore on the islands or reef. It is our opinion that all the data required for diagnosing these shots could be obtained from a diagnostics and firing ship operating over a range of 15 to 20 miles from zero on the first four shots, and a greater range on the 25-40 MT yield shot. Data which would be obtained from equipment, some of which would be mounted on stabilized platforms on this ship, could include: WW
